Re: Can Surfers ever have MRI'S again?

[Guest guest]

The devices cause artifact on MRI's which include the area of the

hips. No danger to you. There is nothing left to examine on MRI of

the hips. Pelvic MRI might be compromised (images). Mri of Lumbar

spine is more limited in the lower area. Otherwise, no problem.

The MR will not damage the resurfacing devices.

All I know is that M in (MRI) stands for Magnetic Imaging and we now

have hips full of metal....sounds scarey.

Peg,

I had an MRI of my lumbar spine about 6 months post op. I was

concerned at first but I was told there was no danger. It was

prescribed by a neurologist, and I cleared it with my OS (Dr. Gross)

first. What does your OS say?

Hi Lynda. I did some research on this because I sleep on a magnetic

mattress pad and discovered that metal implants are required by law

to be non-magnetic. Dr. De Smet saw no harm in my using the pad and

neither did Dr. S at JRI. Therefore, I can see why there would be no

danger as far as the magnetic part of the imaging process goes.

Sorry, I must reply to this misleading and unfounded statement.

NOTE: I AM A RADIOLOGIST USING MRI DAILY.

THE RESURFACING DEVICES ARE COBALT-CHROMIUM-MOLYBDENUM and are not

significantly ferromagmetic. Even steel containing orthopedic

implants are anchored and are safe.

Here is a statement from the website: www.mrisafety.com

" Orthopedic Implants, Materials, and Devices

Most of the orthopedic implants, materials, and devices evaluated for

ferromagnetism are made from nonferromagnetic materials and,

therefore, are safe for patients undergoing MR procedures.

Only the Perfix interference screw used for reconstruction of the

anterior cruciate ligament has been found to be highly ferromagnetic.

Because this interference screw is firmly imbedded in bone for its

specific application, it is held in place with sufficient force to

counterbalance it and to prevent movement or dislodgement.

Notably, the presence of the Perfix interference screw causes

extensive image distortion during MR imaging of the knee. Therefore,

one of the other nonferromagnetic interference screws that are

available should be used for reconstruction of the anterior cruciate

ligament if MR imaging is to be utilized for subsequent evaluation of

the knee.

Patients with the orthopedic implants, materials, and devices

indicated in The List have undergone MR procedures using MR systems

operating with static magnetic fields up to 1.5-T without incident. "

HERE IS AN EXAMPLE OF ONE DEVICE WHICH IS A COBALT CHROMIUM ALLOY

WHICH WAS SPECIFICALLY TESTED:

" Fixation staple (cobalt- chromium alloy)

DONNA:

The MRI machines are hundreds to thousands of times more powerful in

terms of magnetic force than your mattress pad. For example, a 1.5T

(Tesla) MRI unit can easily pull a steel object such as a 1 pound

wrench with considerable force from 8 feet away. Several years ago,

an experimental 4.0T MRI machine at the University of Pennsylvania

pulled apart a floor polishing machine which was brought into the

room after hours by a cleaning worker. MRI is not safe for cardiac

pacemakers, cochlear (ear) implants or your credit card. (pun

intended, not only expensive but will erase it too!)

For this reason, such objects are kept away from the examination

areas, warning signs are posted and workers are trained regarding MRI

safety. Oxygen tanks and other devices are now available which are

not ferromagnetic (aluminum for example).

THE RESURFACING IMPLANTS ARE SAFE WITH ANY MRI EXAMINATION. SOME

ORTHOPEDIC DEVICES CAUSE ARTIFACTS WHICH INTERFERE WITH THE QUALITY

OF THE MRI IMAGES. COMMON EXAMPLES ARE PLATES AND SCREWS USED IN

SOME TYPES OF SPINAL FUSION.

THESE SAME DEVICES CAUSE ARTIFACTS WHICH DEGRADE THE QUALITY OF CT

EXAMS BECAUSE OF SCATERRING OF THE X-RAY BEAM. THE NEWER SCANNERS

CAN OVERCOME THIS WITH THINNER IMMAGING SLICES and IMPROVED

PROCESSING SOFTWARE.
