[Lumbar MR myelography in the prone position: evaluation of nerve root sleeve delineation].
Although MR myelography is able to depict the subarachnoid space noninvasively, its ability to depict the nerve root sleeve is poor. The authors placed subjects in the prone position to increase the volume of spinal-fluid within nerve root sleeves and improve their depiction in MRM. MRM images of five normal volunteers taken in the supine and prone positions were visually correlated. Improved delineation of nerve root sleeves was obtained in all subjects.
