MR of omental myelosynangiosis.

PURPOSE To describe MR findings in patients who have undergone omental transposition (omental myelosynangiosis) for spinal cord revascularization. METHODS Spin-echo MR images, without and with intravenous gadolinium, were obtained before and after surgery in three patients using a quadrature spine coil. Three-dimensional time-of-flight spinal MR angiography was also performed. RESULTS On ro...
