Synopsis

DCE-MRI of endometrial cancer including 41 low-grade type I cancers without squamous differentiation (LG) and 39 with squamous differentiation (LG_w/SD), and 20 high-grade type II cancers (HG) was retrospectively evaluated. Significant difference in the time-intensity curves was found between LG and HG, and LG and LG_w/SD, whereas no significant difference was seen between HG and LG_w/SD. Curve type 3 (initial signal rise which is steeper than that of the myometrium) was more frequent in HG (60%) and LG_w/SD (77%) than in LG (34%). It should be recognized as a pitfall that HG and LG_w/SD may show similar early strong enhancement.
