“…Kinematic images demonstrating organ mobility at MRI can be obtained by a cine-mode display of many images obtained by ultrafast imaging techniques such as fast imaging with steady-state precession (FISP), half Fourier acquisition single-shot turbo spin echo (HASTE), single-shot fast spin echo (SSFSE), and others [50]. MRI using single-shot fast spin-echo images displayed in a cine mode in 52 women with gynecological disorders was able to predict adhesions with a sensitivity of 73% and a specificity of 87% [51]. These results were significantly better than initial reports published in 1989 with a sensitivity of 48% (14/29) [52].…”

Endometriosis corresponds to ectopic endometrial glands and stroma outside the uterine cavity. Clinical symptoms include dysmenorrhoea, dyspareunia, infertility, painful defecation or cyclic urinary symptoms. Pelvic ultrasound is the primary imaging modality to identify and differentiate locations to the ovary (endometriomas) and the bladder wall. Characteristic sonographic features of endometriomas are diffuse low-level internal echos, multilocularity and hyperchoic foci in the wall. Differential diagnoses include corpus luteum, teratoma, cystadenoma, fibroma, tubo-ovarian abscess and carcinoma. Repeated ultrasound is highly recommended for unilocular cysts with low-level internal echoes to differentiate functional corpus luteum from endometriomas. Posterior locations of endometriosis include utero-sacral ligaments, torus uterinus, vagina and recto-sigmoid. Sonographic and MRI features are discussed for each location. Although ultrasound is able to diagnose most locations, its limited sensitivity for posterior lesions does not allow management decision in all patients. MRI has shown high accuracies for both anterior and posterior endometriosis and enables complete lesion mapping before surgery. Posterior locations demonstrate abnormal T2-hypointense, nodules with occasional T1-hyperintense spots and are easier to identify when peristaltic inhibitors and intravenous contrast media are used. Anterior locations benefit from the possibility of MRI urography sequences within the same examination. Rare locations and possible transformation into malignancy are discussed.

“…Recently, MR imaging with kinematic display was reported to provide new information about ileus due to intestinal adhesion and obstruction in adult [5,6]. Imaging while breath-holding may be sufficient for a study within a time interval of approximately 15 to 20 s. This breath-hold study can be repeated several times in one session in adults.…”

Abnormalities in gastrointestinal movement underlie various symptoms in the pediatric population. Although fluoroscopic, manometry, and ultrasonography remain important tools for studying gastrointestinal movement, none can depict the whole gastro-intestine full-size without radiation. The purpose of this study was to evaluate whether kinematic water selective excitation MR imaging (WATS-MR cine) could reveal gastrointestinal movement in childhood. Thirty-six patients (age: 3 to 17 years; 15 male and 22 female) underwent dynamically balanced first field echo (FFE) imaging with a thick slice of water selective excitation without breath hold. The WATS-MR cine was taken at three different times (preprandial, immediately postprandial, and 30-min postprandial) for sequential 5 min. Images were displayed in a cine mode at 10 times the normal speed, and the motion of water in each organ was evaluated. Movement of the stomach, small intestine, and colon could be observed together in a field. This study made it possible to evaluate both preprandial and postprandial gastrointestinal water movement. WATS-MR cine is useful for visualizing gastrointestinal water movement in accessible children older than 6 years without sedation. A cine mode at 10 times the normal speed provided characteristic images reflecting gastrointestinal water movement abnormalities in pediatric patients.
