Abstract:
Objective To evaluate the clinical value of low field strength MRI in judging the invasion of myometrium of endometrial carcinoma in staging Ⅰ.Methods 32 cases with endometrial carcinoma approved to be clinical staging Ⅰ pathologically were evaluated by MRI before operation.The staging results of MRI were compared with pathologic results and analysed with statistic methods.Results According to 1988 FIGO staging the staging of the lesions was further carried out,including stage Ⅰa in 6,stage Ⅰb in 18 and stage Ⅰc in 8 cases.Compared with pathologic results,the sensitivity and specificity of MR in evaluating myometium invasion were 92% and 83% respectively,the staging accurate rate was 78%.Conclusion The endometrial carcinoma stage Ⅰ can be staged further by low field strength MRI,MRI has significant advantage in estimating the invasion of myometrium.
