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.
目的
评估T2加权磁共振成像（MRI）在子宫内膜癌患者术前肌层浸润深度评估及分期中的应用价值。
方法
对33例子宫内膜癌患者术前行MRI检查，并将病理结果与MRI检查结果进行对比。
结果
T2加权磁共振成像对子宫内膜癌分期的总体准确率为84.85%（28/33）。区分Ⅰa期、Ⅰb期和Ⅰc期的准确率为84.62%（22/26）。肌层浸润定位（Ⅰc期与Ⅰa +Ⅰb期之间）的准确率为96.15%（25/26）。病理证实的3例宫颈浸润患者均经MRI准确评估。
结论
MRI有助于评估子宫内膜癌患者的肌层浸润深度及准确分期。
