MRI of spontaneous spinal cord infarction: serial changes in gadolinium-DTPA enhancement.

abstract：PURPOSE:Complex neurovascular lesions in children require precise anatomic understanding for treatment planning. Although 3DRA is commonly employed for volumetric reformation in neurointerventional procedures, the ability to reconstruct this data into CT-like images (3DRA-CT) is not widely utilized. This study demonstr...
