FIG 1. A 38-year-old-man with a left-sided vagal paraganglioma.
A, PC magnitude image (26/9/2/20° [TR/TE/excitations/flip angle]) shows good tumor visualization (large arrow).
B, PC image shows feeding vessels (arrowheads), but ghost artifacts from pulsatility of vessels degrades the image.
C, 2D TOF axial source image (28/5.1/2/60° [TR/TE/excitations/flip angle]) only shows feeding branches from the ascending pharyngeal artery (arrowheads), but the margins of the tumor are only poorly visualized (large arrow).
D, 3D TOF axial source image (25/6.9/1/20° [TR/TE/excitations/flip angle]) shows good visualization of the tumor (large arrow) and also nicely depicts the feeding branches from the ascending pharyngeal artery (arrowheads).
