MRI Safety w VNS Lead Still In Body
Hello Everyone!rn:-)rnrnPlease forgive me in advance for making any newbie mistakes here. I am new and appreciate your kind correction of any errors that I might make.rnrnI am a patient with many, many illnesses. In 2006, I was in the deepest depths of depression and could not see any other way to treat it, other than the newly approved (then) Vagus Nerve Stimulator (VNS) for depression.rnrnNeedless to say, it did not help at all and, after over 2 years of VNS therapy, my doctor and I agreed to turn it off. (It makes the neck muscles move when it is stimulating the vagus nerve, which can get annoying after a while.)rnrnWhen I got the VNS implanted, I was told that I would never be able to have an MRI done, except with special equipment, called a transmit & receive coil. This wasn't a problem because my hospital, Olympia Medical Center, here in Los Angeles, had one of these.rnrnHowever when they upgraded their equipment in the years following my implant, they no longer had a transmit & receive coil for the new machine, and I could not find any place in LA that did have this coil.rnrnNow, since I have so many illnesses in my life, the possibility that I will need an MRI in the future is great. Therefore, I called and spoke with the assistant of the Neurosurgeon at USC Keck Medical Center that implants VNS, and he could therefore remove the VNS.rnrnHowever, the assistant said that, while he could remove the VNS device itself, he would probably have to leave the lead to the vagus nerve in the body because of it's attachment to the nerve has probably grown in at this point.rnrnMy question is this: Will I be able to safely have MRIs in the future with this lead still in my body? At this point, I am thinking that I might have to have MRIs of my brain (Parkinson’s disease, exotropia), wrist (Carpal Tunnel Syndrome), C-spine (prior to doing occipital nerve blocks). Do you have any other comments or suggestions on my situation?rnrnThank you very much for your kindest consideration of my post. I look forward to hearing back from you, and I will await your replies. rnrnBest regards,rnrn~Antonio Dominionrn:-)

What does this mri report mean
Small developing vertical cleft along the radial side of the membranous TFC disc fibers, best seen on image 11 series 5. There is no evidence of contrast transit into the distal radioulnar joint. The remainder of the TFC disc is intact and grossly unremarkable.
Intact intrinsic ligaments. There is no widening of the intervals. There is no contrast in the midcarpal compartment.
Increased interstitial signal within the ECU tendon is likely due to tendinopathy and a developing longitudinal split. The remaining tendons are grossly unremarkable.
Normal caliber median and ulnar nerves.
Minimal generalized wrist osteoarthrosis with minimal to mild chondromalacia, small intraosseous cysts and minimal osteophytosis.

ACR Compliance Question
In 2010, we submitted a knee for our MSK module in our ACR accreditation. Over the past three years, a few new radiologists have come on board, and the preferred knee protocol has changed. But we've continued using the sequences that were submitted to ACR in order to be compliant. At this point, we have three different sequences that NONE of our radiologists care about... and it's basically adding time to each procedure without being beneficial to the patient. But we HAVE to perform those scans.

We are currently getting re-accredited - but we are submitting a wrist this time for the MSK module. Once we get approved, can we drop the unnecessary sequences in the knee and be compliant since we will be using the submitted sequences in the wrist?

6-1.5T MAGNETS, DIFFERING GRADIENTS
I assume that you mean a t2 fat suppressed sequence. Differing gradient strengths have only an indirect effect on these images. The fat saturation sequences require additional pulses which take time to execute; stronger gradient systems can execute these pulses faster.

If you see different results, it can be caused by a number of factors; if you can describe the differences, that would be helpful. Generally speaking, the quality of the magnet homogeneity makes a big difference. If the small FOV scans (wrist) look different from magnet to magnet, that's probably not the cause.

You should ask your MRI applications specialist about this, and pay attention to the TE and bandwidth. Are the FOV and number of steps the same?

SPAIR movement artefact
Dear all,
When scanning wrists in our Avanto MR always the penultimate slice in the transversal series shows a movement artefact. This happens with all patients and always the penultimate slice. We found out that using regular fat saturation this does not occur, with SPAIR (which is preferable because of the frequent susceptibility artefacts in arms/wrists) however it happens all the time. The simple solution for our radiology staff is to use normal fat saturation instead of SPAIR, however we are intriged by this problem and were hoping that anyone also experienced this problem and maybe found an explanation.
Because it happens in only 1 slice we are suspecting some kind of interference of the slice selection pulse with the SPAIR pre-pulses.
Any input is appreciated,
thanks in advance, Matthijs
