摘要:
The aim of this article is to review the magnetic resonance (MR) findings of pelvic floor descent and pelvic organ prolapse in women. In addition, a detailed grading system of pelvic organ prolapse and pelvic floor relaxation based on dynamic MR imaging is presented. The technique described here uses very fast MR sequences, is reproducible and easily learned by radiologists and technologists, is well accepted by patients, and provides as much information as traditional projectional X-ray imaging. Reference points are the pubococcygeal line and puborectalis muscle sling. The grading system is based on degree of organ prolapse through the hiatus and the degree of puborectalis descent and hiatal enlargement.

摘要:
Ultrafast magnetic resonance imaging (MRI) sequences have changed the use of MRI to evaluate fetal abnormalities. Currently, the best application is the evaluation of suspected brain abnormalities found on ultrasound. MRI differentiates the various types of fetal ventriculomegaly. Superior posterior fossa visualization allows differentiation of Dandy-Walker malformation from a large cisterna magna. Anomalies of the corpus callosum can be seen. MRI also is valuable in the evaluation of fetal giant neck masses for planning delivery of the baby and surgery for life-threatening airway obstruction. In the chest, MRI differentiates masses such as diaphragmatic hernia, cystic adenomatoid malformation, and sequestration, and it aids in planning fetal surgery because MRI directly visualizes the position of the lung, liver, and bowel.

摘要:
Magnetic resonance imaging (MRI) is gaining momentum for staging gynecologic malignancies. MRI staging is an adjunct to clinical and surgical staging in women with cervical or endometrial cancer, respectively. For women with possible adnexal pathology, MRI is useful for lesion characterization. In patients with ovarian cancer, MRI determination of disease extent helps treatment planning, either as a surgical roadmap or to identify nonresectable patients.

摘要:
Magnetic resonance imaging (MRI) of the pelvis can characterize a wide variety of ovarian lesions. We discuss MRI strategies for identification and characterization of ovarian neoplasms and correlate MRI findings with lesion gross pathological and histopathological structure.
