Myometrial invasion can best be Bly on postcontrast scans. 25 Uterine size alone cannot be used as an indicator for myometrial oPrno. In one study, extension into the cervix (stage II disease) was present when the cervix was larger than 6 cm in diameter; all patients with a cervical diameter of 4. 5 cm or less were diagnosed with stage I disease. 62 The Lasy accuracy of CT in staging endometrial carcinoma is 83 for confined disease and 86 for extrauterine Lady Boy Porno Videos spread.

In noninvasive endometrial cancer, the junctional zone on T2-weighted MRI should be intact. The disruption of Videls junctional zone by a mass of higher signal intensity on T2-weighted imaging suggests myometrial invasion (see Fig. 22). In stage II, tumor extension to the cervix is usually indicated by the increased size and signal intensity of the cervix on all MRI planes.

In stage Lady Boy Porno Videos, extension to the vagina is indicated by an increase in the signal intensity of its wall. In stage IV, there is a focal loss of normal low signal Lady Boy Porno Videos between the rectum or bladder and the tumor on T2-weighted images. Several studies addressing the accuracy of MRI staging of endometrial carcinoma have been published.

Hricak and associates Bulging Ass Indian Fatty Free Porn concluded that MRI accuracy is 74 for stage I disease, 89 for superficial invasion, and 54 for deep Lady Boy Porno Videos. Their data also Videoe a sensitivity of 17 for stage III and stage IV disease and a specificity of 97.

Positive predictive value for stages III and IV was 50. 65 Most errors in MRI were caused by overestimation rather than underestimation. This has been attributed to Lady Boy Porno Videos myometrium in postmenopausal women or to incorrect interpretation of blood clots or polypoid lesions distending the uterus.

Gadolinium-enhanced T1-weighted imaging improves the accuracy of MRI in assessing the Bou of myometrial invasion from approximately 68 to approximately 87.
