“TRU-SCAN MRI” IN CLINICAL PRACTICE –
A RADIOLOGIST’S PERSPECTIVE

Case Study #6: Position Related Disc Herniation
Seated image (left) shows disc bulging at C4/5, 5/6 and 6/7. Placing the patient in the seated, extension position shows a C4/5 disc herniation with compression on the thecal sac and cervical cord.

Case #6

The remaining 10% of the changes I see are in the thoracic spine. The percentages I have presented are in part a result of the ordering patterns of treating physicians. I interpret many more cervical than thoracic MRI’s. These percentages are probably skewed further because we encounter many cases I may not otherwise see (in that the patients have been pre-selected for imaging on our TruScan MRI by referring clinicians).

My experience so far allows me to state without hesitation that there is tremendous value in imaging patients in different positions, especially with regard to spine imaging. Please take the time to review a small portfolio of real patients from my radiology practice and see for yourself. Until a large scientific study is performed, we will have to base medical decisions on the information we have available. I believe the proof is in the MRI images and the pictures speak for themselves.

Case Study #7: Instability and Disc bulging - Seated vs. Standing
Seated image (left) shows forward subluxation of L4 on L5 and disc bulge at the L3/4. The standing view, however, shows herniation at L3/4 level. Sometimes differences are seen between sitting and standing.
