  		Figure 1.  Confirmed adhesions between the uterus and loops of the small intestine and closure of the Douglas pouch due to endometriosis in a 23-year-old woman. Static T2-weighted image shows a retroflexed uterus. The intestinal loop adjacent to the anterior wall of the uterus lacks peristalsis focally and lacks the sliding fine movement relative to the anterior wall of the uterus (arrow), indicating adhesion to the uterus, in contrast to other intestinal loops that show active peristalsis (arrowhead). See Movie 4.

  		Figure 2.  Confirmed adhesions between the uterus and endometrial cyst and closure of the Douglas pouch due to endometriosis in a 39-year-old woman. Static T2-weighted image shows an endometrial cyst behind the retroflexed uterus.

  		Figure 3.  Static turbo spin-echo image shows a sustained uterine contraction in a 23-year-old healthy volunteer. No abnormality, excluding possible adenomyosis or leiomyoma, is seen.

  		Figure 4.  Confirmed endometrial carcinoma (stage Ib) in a 79-year-old woman. Static T2-weighted image shows that the endometrium is abnormally thick for a woman of this age. A tumor with low signal intensity protrudes from the posterior wall of the uterus, indicating corpus carcinoma. The junctional zone is well preserved at the site of the tumor, indicating no myometrial invasion.
