Fig. 4B. —Postcontrast fat-saturated axial images of 56-year-old man
with hypopharyngeal cancer. Volumetric interpolated breath-hold examination
(VIBE) image (TR/TE, 4.3/2.0; flip angle, 15°) (A) and spinecho
T1-weighted image (497/17.0) (B) of hypopharynx show tumor located at
left pyriform sinus (arrows). Lesion is relatively unclear on VIBE
image. In this case, overall image quality and tumor conspicuity were
evaluated as being better on spin-echo T1-weighted image than on VIBE image.
VIBE image was scored as 4, whereas spin-echo T1-weighted image was scored as
5. Artifacts were scored as 4 on both VIBE and spin-echo T1-weighted
images.
