FIG 3. A 38-year-old-man with a left-sided vagal paraganglioma. Slightly anteroposterior, oblique MIPs are presented. A muscular branch from the vertebral artery adds to the extensive vascularization of this tumor.
A, 3D PCA MIP (26/9/2/20° [TR/TE/excitations/flip angle]) hardly shows a branch from the occipital artery (arrow) as tumor feeder. The muscular branch from the vertebral artery is not at all visible.
B, 2D TOF MIP (28/5.1/2/60° [TR/TE/excitations/flip angle]) not only shows supply from the occipital artery (arrow), but a small feeding branch from the vertebral artery (arrowhead) also is depicted.
C, 3D TOF MIP (25/6.9/1/20° [TR/TE/excitations/flip angle]) shows more clearly than the 2D TOF MIP vascularization from the occipital artery (arrow) as well as from the vertebral artery (arrowhead).
