Barb, before undertaking ANY types of tests for ANYTHING, I believe that it is

important to get a complete explanation from the the doctor of what the test is

for, exactly what will be done, what, if any drugs will be used on you, what the

effects of those drugs and/or radiation might cause, and if there are any less

invasive or dangerous tests available?

 

Then I think you should be allowed at least one day to make up your mind as you

how you feel about getting any particular test.

 

When my cardio wanted to give me a nuclear stress test. I asked the questions.

After I heard what would be done and what the alternative was I opted for the

alternative and have had that test twice in the space of three years. I have not

been sorry since a regular stress test on a tread mill was non invasive. I was

not afraid of having a heart attack from the stress, because I never get an

atrial fibrillation attack from exercise. It usually happens when I'm sitting

down. We are all different, and we need to be proactive in our health care and

protecting ourselves from undue substances being introduced into our bodies,

from any source if possible.

 

These are just my feelings, and I'm not telling anyone that they should or

should not do what their doctor says. On the other hand, I do feel that a

patient is entitled to informed

consent about any type of diagnostic study or treatment.

which type.  I read there are two types.  The reason I'm looking into this is

doesn't make sense to me, since I thought it would be done in radiology.  It's

not a hospital, but a large medical group with lab and testing facilities on

site.  They have a radiology department.  I definitely want to avoid another CT

scan, especially since I read that a person with thyroid nodules will often be

found to have high thyroid hormone levels for the first time after being

injected with dye for a CT scan.  I had one last year, and posted my next blood

test here, which showed TSH over 8.

You probably already know this, but here are the two types of scans:

" There are two types of thyroid nuclear medicine tests. Both assess the health

of your thyroid, a gland in your neck that controls metabolism. A thyroid scan

produces a picture of the gland to help evaluate any lumps or inflammation, or

to investigate the cause of an overactive thyroid. A radioactive iodine uptake

test is performed to see if your thyroid is functioning normally and to

determine why thyroid hormone levels may be elevated. For both types of test, a

small amount of a weakly radioactive substance, known as a radionuclide, is

either injected into a vein or given to you as a pill

A thyroid scan is usually ordered when a physical examination or laboratory

finding suggests that the thyroid is enlarged. If laboratory tests show an

overactive thyroid, a radioactive iodine uptake test may be ordered at the same

time.

A radioactive iodine uptake test measures the amount of radioactivity in your

thyroid after you've been given a relatively small dose of radioactive iodine in

pill form. Your thyroid gland absorbs iodine and uses it to make hormones.

Therefore, the amount of radioactive iodine detected in your thyroid gland

corresponds with the amount of hormone your thyroid is producing. "

http://www.health.harvard.edu/diagnostic-tests/thyroid-scan.htm

It is my understanding that the above tests are done with a camera and a probe,

not x-rays.  Please correct me if I'm wrong.

All I was told is that I am scheduled for a scan, I will go in briefly, leave

for two hours, go back, and then leave again for four more hours.  Then I'm to

go back again.  They didn't say why.  I have not been told to avoid shell fish

or thyroid medication, which I've read the doctor might suggest before a scan. 

I was told to fast for 12 hours before going.  After leaving the first time

there is no food allowed for those two hours.  After leaving the second time, I

am allowed to eat before going back again in four hours.  Do you think this

indicates they are doing both types of scans?  I'm trying to avoid unnecessary

tests and any expense associated with them.

I'm sorry to be asking you this because I think my doctor should have given me

more information.  Which test do you think I need?  Why do you think a needle

biopsy has not been suggested?

Thanks again,

The radioactive iodine scan does not use a dye, so it does not have the

side effects you and Roni mentioned. It is a nuclear procedure, so the

facility may well be in the cardiology lab outside a hospital.

Neither of these is a CT scan, which uses a NON-radioactive form of

iodine as a dye. I was definitely referring to the uptake scan, which

uses minimal amounts of iodine. The imaging version uses a lot more, but

I doubt they would go to that for an initial assessment.

> ... It is my understanding that the above tests are done with a camera and a

The imaging version is done with a bank of gamma ray cameras. The uptake

test can use a single detector that is moved around. In both cases, the

radiation source is in your thyroid, while X-rays would come from an

external source. Both will have similar procedures and food

restrictions. Again, the imaging method would be more likely to be used

after a biopsy showed it to be necessary.

My son did the uptake test first, which indicated we needed to perform

biopsies at regular six month intervals. However, since he requires

blood thinners for a heart valve that was replaced, each biopsy would

have required admission to the hospital for nearly a week, while they

replace his Coumadin with heparin and then restored it. So, we opted to

just remove the thyroid entirely, so he would only have to go through

the heparin protocol once. This turned out to be a lucky decision, since

the nodules removed turned out to be malignant.

Afterwards, they used radioactive ablation to " mop up " any remaining

cells. This allowed them to use the gamma camera scan to look for any

hot spots. So, we have effectively done both nuclear procedures but not

the biopsy.

Thanks for sharing your feelings with me Roni. It sounds like you definitely

did the right thing for you.

I can't get in to see the endocronologist until 11-17, and my internist thought

I should have this scan before going there, to make sure it's okay to wait that

long for the appointment. That was after he told me he didn't think it was

Cancer. Then he said it wasn't Cancer, I think so I wouldn't bother him. As

Chuck has said, there is no way to know until the tests are done. The

internist's office scheduled the test based on the results of the ultrasound.

I'm not pleased with the fact that they don't seem to have time to talk with

anyone. After I had the original bloodwork, and received the message when I got

home that medication was being prescribed for Hypothyroidism, I asked a couple

of questions when I returned the call. When I had more questions, it was

suggested that I make another apointment with the doctor to discuss it, so I

did. That's when he told me it was a common problem, he treats it all the time,

and " There isn't going to be anything else, " when I suggested additional tests

might be in order. I told him my Dad and my maternal Grandmother had needed

surgery to have their thyroid removed, and he said that was because they were

overactive. He has no idea, because I don't even know, and there's no one left

to ask.

I'm considering going to the Mayo Clinic in ville for a diagnosis. My

Son only lives about an hour from there. I could drive up to his house, which

takes about two hours, and I'm sure he would go with me.

I appreciate your advice.

Thanks for the information Chuck. How is your son now? It sounds like you have

been through a lot with him. I sure hope he's doing well.

This is all so confusing to me. I think what you're saying is that if I do need

a scan, which I previously understood you to say was essential, it should be the

uptake scan. Is that right? You said it's the one your son had first which

determined he needed biopsies. So if they want to do both, I should refuse the

imaging version?

That sounds like a good idea. If you go there or where you are, please make sure

to find out exactly what is in your throat, whether or not it is cancerous, get

hard copies of all tests and finally ask what all the possible treatments are,

including thyroid therapy. Even if they say it is cancerous, give yourself a day

or two to digest the diagnosis and the other information so that you can make an

informed and less panicked decision (I'd feel panicked, but I know by now to

Hi again,

After asking about the two types of thyroid scans, I received this response from

you Chuck.

" The imaging version is done with a bank of gamma ray cameras. The uptake

test can use a single detector that is moved around. In both cases, the

radiation source is in your thyroid, while X-rays would come from an

external source. Both will have similar procedures and food

restrictions. Again, the imaging method would be more likely to be used

after a biopsy showed it to be necessary. "

This morning the department where the test will be done said the same amount of

iodine is required for both tests. According to them it wouldn't make any

difference if it was for one test or two. I will take the iodine pill, leave

for two hours, go back, and they will use the detector you mentioned to see how

much iodine has been taken up. Then I leave for another four hours, go back,

and they will use the detector again to see if more iodine has been taken up.

After that they plan to do a scan with a camera, so it appears they want me to

have both tests.

You also mentioned that the radiation source is in the thyroid Chuck. Because

the iodine is taken in pill form, it doesn't just go to the thyroid does it?

You mentioned the second test would be " more likely to be used after a biopsy

showed it to be necessary. " As you know I haven't had a biopsy Could they

possibly be doing this instead of a biopsy? Or maybe they prefer to do both

while I'm there, to prevent a trip back for a second test? Whatever the reason,

do you see any harm in having both? No doubt it will cost a lot more, but I

mean other than that.

I thought I read here that the scan takes more iodine than the uptake test, so I

specifically asked about that, and she insisted it was the same amount of iodine

for one or both.

My apologies for being so ignorant about all of this. Everyone's input is

welcomed and appreciated.

Thanks,

Barb

Thanks, he is doing well. We still have concerns about his heart. In his

life, he has had three open heart procedures. He still needs oxygen when

he sleeps or takes a bath, but otherwise his life is pretty normal.

If that is what they want to do, I would ask for an explanation. They

should compare the risks and benefits of any procedure for you.

I would be surprised if they chose the imaging procedure first, since

that is more of a preparation for surgery.

That is a surprise to me. They may have made the imaging more efficient.

The Am. College of Radiography guidelines I looked up said that the

uptake test dose is 0.2 to 0.4 millicurie, while the scan requires about

5 millicuries. Both may be contrasted with ablation, which is typically

50-100 millicuries.

That's two things you have mentioned that make me personally nervous about this

facility.

 

Barbara, is it possible for you to go to another imaging facility which might

possibly be doing

a more professional job? Also, I would ask the doctor why they want to do what

they want to do?

Are they prepping you for surgery even before all the tests are in?

Unfortunately, some doctors

think because they say something needs surgery, that's it. You are entitile to a

second opinion.

Chuck & Roni,

Thanks for replying. I don't feel good about any of this. I think the reason I

can't ask a doctor the questions I want to ask, is that I'm being scheduled for

these tests before seeing the endocronologist. So, there is no one to ask,

except the person I talked with in the cardiology department where the test is

scheduled to be done. The Internest said the test is essential, but I thought

it was just an iodine uptake scan, and from what you said Chuck, that does seem

necessary.

It seems to me like the thing to do first would be to see the endocronologist.

Then when he suggests testing, I could ask questions to determine if I need or

want the tests. I can't get in to see him until the 17th, and the tests are

scheduled for this Thursday. Of course if there's a possibility I have Cancer,

I need to find out ASAP. If I don't, then there is more time to make other

appointments and get other opinions.

Will the uptake test or the scan show if I have Cancer? Wouldn't a needle

biopsy do the same? I thought the purpose of a needle biopsy was to test for

Cancer, but it has not been mentioned by the internist. I definitely plan to

get a second opinion, but would like to have a first opinion before too much

more time passes. All I want to do is find out what's wrong with me, without

having any unnecessary or risky tests that might cause more problems.

I'm probably more upset over this than I should be, but I also have to go back

an have my pap test done over also, since I'm being told the sample didn't have

enough cells. They're saying this is not uncommon in women over 60, but it's

just something else to be concerned about.

Thanks so much for taking the time to read and answer my questions.

Wow Chuck! What you son has gone though doesn't sound anything like normal to

me. Poor guy! How old is he? Three open heart procedures and oxygen to sleep

or take a bath, indicates there is still much progress to be made. I hope and

pray that things will turn around for him, and he will be able to live a more

normal life, which isn't interrupted by surgeries and being hooked up to oxygen.

I apologize for answering this e-mail second. I was reading my e-mail backwards

(duh), so read it after Roni's.

I would love to ask for an explanation and comparison of risks to benefits as

you suggest, but as explained in my previous post, there is no one to ask. I

doubt the endocronologist's office would take the time, since I haven't seen him

yet, and he didn't order the tests. I don't want to talk to the internest about

it because I don't trust him.

Barb, I hope you don't think I'm being impertinent, but I think you

need in person support. Do you have a daughter or neice or good

friend that could go with you to these doctors and be there when

you ask questions and hear their answers? Maybe you have a son

who could do this for you. These things can get very overpowering

and speaking as a senior who also is alone, I can relate to that.

 

I wouldn't think the needle biopsy should be the first test. Perhaps

you could call the facility and ask for the chief radiologist and ask

him/her your questions. I'd have them written down in order first so

you don't forget anything. I know if I don't write them down I always

manage to forget something.

No, it shows whether the nodules are actively producing hormones or not.

Since the biopsy carries some risk of opening an otherwise enclosed

nodule, logic requires they rule out benign conditions before the biopsy.

Mike is 36. His first procedure was a pulmonary valvulotomy at 10 days.

He weighed five pounds after the procedure. His last heart surgery

replaced both his mitral and pulmonary valves. Last spring he had the

thyroidectomy followed by radioactive iodine ablation. He now seems to

be back to normal, although we still have to monitor his blood thinners

and potassium carefully.

He also had a spinal fusion for scoliosis when he was 12. That took over

nine hours.

I feel so bad for your son. He's gone through so much, and of course, you and

your wife, as his parents went through it all with him. I pray that he will be

healthy now and not need any more procedures. He's a brave kid.

 

I have a question, how do you monitor the potassium?

Thanks Roni. I don't think you're being impertinent, and appreciate your input.

I do have someone to go with me, if I just had a place to go, sit down, and talk

with a doctor. I already have a list of questions, and would love to ask them

and hear answers. I'm sure this is something I will be able to do when going

for a second opinion, but don't know how it's possible now. They are all so

busy, and it takes weeks or months to even get an appointment.

Your idea about calling and asking to speak with the chief radiologist is a good

one, and I'll give it a try. What I've experienced so far though, is that

doctor's don't return calls. It's either a nurse, a secretary telling me what

the doctor said, or someone else who isn't a doctor who calls back.

Chuck,

Your son sounds like a living miracle! I can't imagine how difficult it must

have been for you and your family to go through all those procedures. It's good

news that he seems to be " back to normal. " I pray he will continue to improve,

and be able to put all of this behind him.

He was getting a blood draw every other week for INR (thinner) and

potassium. His endo wants to look at another panel that includes

potassium every week for awhile. I'm not sure what he is fishing for, at

least not exactly. One of his cardiac issues force us to give him

whopping diuretics, so we have to work to keep the electrolytes up.

Normally, they take weeks between checks on the thinner, but his current

situation requires all of these to be monitored more frequently.

Well I think I mentioned that diuretics give me atrial fibrillation attacks the

next morning. Draining out that fluid so fast probably adversely affects the

heart, so it does make sense to me that the doctor is checking that. He sounds

like a good doctor.

One of the key indicators is how rapidly something is changing or

growing. They may be wanting a baseline image for that. However, the

ultrasound can also measure size, and it does not use ionizing

radiation. Also, if they can get two tests off one dose of iodine, then

they might as well get all the information they can get. My sources said

the uptake test required much less activity than the scan, so this

possible explanation would not have made sense before.
