Fig 3. Coronal curved multiplanar reformation of the second dynamic phase of the CE-MRA examination of the posterior spinal cord surface. The posterior median vein (black arrowheads), as well as 2 draining posterior radiculomedullary veins (thoracic vertebral levels 9 and 11), are displayed (black arrows). The great radiculomedullary vein, which is defined as the largest of the radiculomedullary veins, entered the epidural space at the level of the 11th thoracic segmental vein on the right side.
