Rapid MRI detection of vertebral numeric variation.

OBJECTIVE

Vertebral column variation is a common, often overlooked finding on traditional spine MRI. Standard localizers do not image the entire neuroaxis, masking variation. The purpose of this study was to use a subminute automated spine survey iterative scan technique (ASSIST) to evaluate 207 patients undergoing thoracic spine MRI.

CONCLUSION

We found variation in 7.7%, with 69% of these cases going unreported. To enhance patient care and decrease medicolegal implications, we recommend ASSIST be performed on all thoracic and lumbar examinations, with variations documented.
