OBJECTIVE: To evaluate the usefulness of T2-weighed magnetic resonance images (MRI) in preoperative assessment of the depth of myometrial invasion and the staging of patients with endometrial carcinoma.
METHODS: 33 cases of endometrial carcinoma were examined by MRI before operation, and the pathological findings were compared with MRI findings.
RESULTS: The overall accuracy of T2-weighed magnetic resonance images in staging endometrial carcinoma was 84.85% (28/33). The accuracy for distinguishing stages I a, I b and I c was 84.62%(22/26). And the accuracy for localization of myometrial invasion (stage I c between stages I a + I b) was 96.15%(25/26). All the 3 cases with cervical invasions confirmed by pathological findings were accurately assessed by MRI.
CONCLUSION: MRI is useful in assessing the depth of myometrial invasion and accurate staging in patients with endometrial carcinoma.
