[Magnetic resonance imaging in the diagnosis and staging of endometrial carcinoma]

The value of magnetic resonance imaging (MRI) in the diagnosis and staging of endometrial carcinoma was studied in 43 cases of clinically suspected endometrial carcinoma and 7 normal women. All of the 43 cases showed abnormal endometria measured by MRI, among which were pathologically proven 40 cases of endometrial carcinoma, 2 cases of endometrial polyps and 1 case of adenomyosis. This suggested that MRI showed a high susceptibility in the diagnosis of endometrial carcinoma, and a lack of specificity. MRI could predict myometrial invasion, its accuracy being verified by surgico-pathological findings in 11 of 13 cases. MRI staging was correct in 10 of the 13 primarily operated cases, and only half of the clinical staging was in conformity with surgical staging. The results suggest that MRI is useful in the staging of endometrial carcinoma and therefore is of value in the choice of treatment planning, although it is not yet an ideal diagnostic aid to detect small metastatic pelvic lesions.
