Figure 8a. Persistent disease 4 months after radiation therapy. (a) Sagittal T2-weighted fast spin-echo MR image (3,500/75) shows an inhomogeneous high-signal-intensity mass (arrows) in the uterine cervix and invasion of the posterior wall of the urinary bladder. (b) Sagittal T2-weighted fast spin-echo MR image (3,500/75) obtained 2 months later shows that the mass (arrows) has the same signal intensity.
