Fig 3. Precontrast (top row) and postcontrast (bottom row) axial sections at different locations through the thoracolumbar spine region showing several important vascular features (Ao, aorta, IVC, inferior vena cava; HV, hemiazygous vein). Blood vessels penetrating the spinal cord can be visualized in D and E (arrow). The epidural venous plexus is demonstrated in F. The artifacts due to the implantation of radio-frequency coil on the dorsal side are also visible. These images are acquired after administration of liposomal-Gd.
