Figures
- FIG 1.
Illustration of the hips elevated with the assistance of a foam wedge, and the head elevated on pillows, allowing contrast to pool in the thoracic spine.
- FIG 2.
Examples of CVFs seen on CTM. Axial image from CTM obtained with the patient in the right lateral decubitus position (A) shows venous contrast opacification, indicating the presence of a CVF in a segmental spinal vein (white arrow). Axial image from CTM performed with the patient in the prone position (B) shows contrast opacification of the internal epidural venous plexus within the spinal canal (white arrow), also diagnostic of a CVF.
- FIG 3.
Examples of equivocal CVFs requiring adjudication. Axial (A) and sagittal (B) images from CTM in a single subject show subtle increased attenuation of a foraminal vein and adjacent segmental spinal vein (white arrows); this increased attenuation was judged to represent a CVF after a consensus read. Axial (C) and sagittal (D) images from CTM in a second subject whose faint increased attenuation posterior to the perineural diverticulum (black arrowhead) and anterior to the same diverticulum (white arrowhead) was judged to be not definitive enough to diagnose as a CVF following consensus read.
