    It sounds like you know your physics. I can tell you that even a good 1.5 tesla image can occasionally be misleading as compared to a 3.0 image. I am sure the 7.0 newest images will overshadow even current technology.

    The other problem with stand-up MRIs is the capture time. Images can contain significant motion artifact as the patient cannot stay in one position for any extended length of time, especially if they are in pain. I am sure there are acceptable images produced by the Fonar machine but many studies I have seen have needed to be repeated if surgical consideration is needed.

    I am enjoying your lively discussion and would like to provoke more thought on the topic of standup MRI. Putting motion artifact aside and making all other things (Magnet strength and technician skill etc.) equal, Dr. Corenman, and MRI4u do you think there is value or an advantage in performing a standup MRI as opposed to a traditional. Also would you see a benefit in a true standing weight bearing MRI, verus a seated at either 90 degrees or reclined position versus the traditional supine position. I look forward to your replies. -George

    My issue is, I have to trust the MRI images implicitly to be absolutely accurate in performing surgery. The good news is that these images have to correspond with the history and physical examination and if they don’t make sense, I can have other tests performed to confirm the findings. There are times the Fonar images can be used for surgical planning but I have seen times that a more precise scan is necessary.

    The only time that I think an MRI scan needs to include motion images is in the rare case of a hydraulic disc causing radiculopathy. This is a disc that bulges posteriorly with load and the bulge reduces with unloading. Flexion/extension X-rays will not diagnose this disorder. However, this type of disc can be diagnosed with a discogram. I see this type of disc about once every two years so ordering a motion MRI for every radiculopathy case would not be cost effective as the necessity for possible repeat scanning.
