| MRI 1w/kg sequences Siemens Avanto FIT |
I have recently been asked to build protocols for Spines and extremities that are 1 watt per kilogram SAR. In speaking with Applications at Siemens they inform me that I can only change certian parameters to help lower SAR but it will all be dependent upon each patient and which sequences are running. I need to present to our MRI QA commitiee if we can or if we cannot do 1w/kg SAR as we are determining if we can scan cochlear implants? Does anyone have any ideas or solutions?
Thank You
Will R.

| Crash cart requirements for contrast |
We are an outpatient surgical center with an MRI department and on-site physicians and we frequently have contrasted exams. What are the MRI department-specific requirements for the crash cart? We currently have a fully loaded crash cart that is honestly stocked with a lot of medications we would never administer even during a reaction. So in an effort to cut restocking costs, what are we REQUIRED to have on hand? And which organization would govern that? (The ACR white paper on MRI safety doesn't seem to cover this topic.)

'Max. SAR per second - Whole Body (Normal, 1st Controlled, 2nd Control)'

| Max. SAR per second - Whole Body (Normal, 1st Controlled, 2nd Control) |
Hello fellow imaging technologists & professionals!
I'm involved in the development of a new type of cardiovascular medical device.
This device employs MRI technology/scans to power, guide, and control the medical devices and their active elements.
I conducted some research into the following question, "How much x-ray energy is allowed within a human every sec from a MRI machine?"
With regards to SAR rates, I understand that these are the upper-limits for the various settings for a full-body scan:
Normal setting: Whole body SAR - 2
1st Level Controlled: Whole body SAR - 4
2nd Level Controlled: Whole body SAR - >4
Would you agree with these calculations that I performed, and if not, why? And what would be a better way to calculate this?
For WHOLE BODY SAR:
-SO IF IN NORMAL MODE FOR MRI, THE MAX. ALLOWABLE SAR IS "2" OVER A 6 MIN. PERIOD, THEN
-6 MIN. = 360 SECONDS
-2 / 360 = 0.00555
FOR 1ST LEVEL CONTROLLED:
-SO IF IN 1ST LEVEL CONTROLLED FOR MRI, THE MAX. ALLOWABLE SAR IS "4" OVER A 6 MIN. PERIOD, THEN
-6 MIN. = 360 SECONDS
-4/ 360 = 0.01111
Other questions -- What is the difference between normal setting, 1st conrolled and 2nd controlled?
What is the clinical purpose of these various settings?
Any insights that you would be willing to share in regards to the above would be greatly appreciated!
I was trained and registred as a diagnostic echocardiographer, specializing in cardiovascular ultrasound, therefore I need help with MRI information/specifications. I am now focusing on the medical device field, but this technology/device happens to be highly dependent on MRI technology.
Any help from the group would be greatly appreciated!!
Thanks & regards,
Clifford Thornton

| What am I looking at? |
My wife has had severe back pain for months and the insurance finally allowed us to get an MRI. Can anyone tell me what we are looking at here? and maybe a guess at a diagnosis? Our doctor is on vacation and we won't have an answer for about another week. http://imgur.com/a/spxfp Thank you in advance!
