title: [Assessment of magnetic resonance imaging in preoperative staging of endometrial carcinoma].
abstract: 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.
  
  
  CONCLUSIONS
  MRI is useful in assessing the depth of myometrial invasion and accurate staging in patients with endometrial carcinoma.
