Fig. 1From: MRI-assessed tumor-free distance to serosa predicts deep myometrial invasion and poor outcome in endometrial cancerSchematic overview of the different measurements marked on an axial oblique slice of the uterus. The myometrial wall is colored pink, tumor is gray and the endometrium/uterine cavity is light blue and the boundary between the myometrium and endometrium is delineated with a dotted black line. APD (blue arrow): maximum anteroposterior tumor diameter. MW (orange arrow): presumed thickness of the myometrial wall. DOI (green arrow): absolute depth of myometrial tumor invasion in the region exhibiting proportionally deepest invasion. TFD (pink arrow): tumor-free distance to serosa in the area exhibiting deepest invasion or shortest distance to serosa. The conventional dichotomous imaging parameter, iDMI, myometrial invasion of ≥ 50% of the myometrial wall is determined by DOI relative to MWBack to article page
