It is well known that the prognosis of endometrial cancer is related to the degree of myometrial invasion. But practically, preoperative evaluation of the myometrial invasion is very difficult. We aimed to clarify whether the degree of myometrial invasion in stage I endometrial canser could be evaluated by MRI. The maximum transverse diameter of the tumor to that of the uterine body: T/U was calculated in each of 15 cases. The degree of myometrial invasion was confirmed pathologically, including 7 cases less than 1/2 and 8 cases more than 1/2 of myometrial cancer invasion. We found that T/U more than 0.3 indicates the likelihood of cancer invasion in more than 1/2 the myometrium by ROC curve analysis. It is sugested that the simple T/U parameter is useful in stage I endometrial cancer involving myometrial invasion.
