Figure 3b. Appearance of the uterus in a 26-year-old woman after cesarean section at 31 weeks gestation. MR imaging was performed 8 days later for evaluation of cervical cancer. (a) Sagittal T1-weighted image shows a high-signal-intensity lesion (arrowheads) at the site of uterine incision, a finding consistent with a hematoma. (b) Sagittal T2-weighted image shows a bandlike appearance of the uterine incision (arrow) and the hematoma (black arrowheads). There are multiple dilated veins (white arrowheads) in the posterior wall.
