Fig. 7C —35-year-old woman with pelvic pain; images obtained at 3 T.
Unenhanced axial T1-weighted fat-saturated 3D fast spoiled gradient-recalled
echo image through pelvis (3.5/1.55; flip angle, 12°; bandwidth, 100 kHz;
imaging time, 22 seconds; field of view, 36 cm; slice thickness, 4 mm; matrix,
320 x 256). There is no visible difference in signal between images
A, B, and C. Voxel size is the same. Increased bandwidth (which
reduces signal) results in decreased TE (which increases signal due to less
T2* decay), and these effects counteract each other. However, breath-hold time
is shorter with longer-bandwidth acquisition, which results in less potential
motion artifact from breathing.
