Preoperative Evaluation of Myometrial Invasion in Endometrial Carcinoma: Prospective Intra-individual Comparison of Magnetic Resonance Volumetry, Diffusion-weighted and Dynamic Contrast-enhanced Magnetic Resonance Imaging.

Aim: The purpose of this prospective study was to compare the diagnostic performance of diffusion-weighted (DWI) and dynamic contrast-enhanced imaging (DCE) and volumetric analyses in the preoperative assessment of myometrial invasion in patients with endometrial carcinoma.

Materials And Methods: Thirty-five patients with endometrial cancer underwent preoperative magnetic resonance imaging including DWI and DCE for evaluation of the depth of myometrial invasion and volumetric analyses [tumor volume (TV), uterine volume (UV), tumor to volume ratio (TVR=(TV/TU)×100)]. The results of the evaluations were compared to the histopathological examinations.
