Abstract

Purpose: Our goal was to investigate the usefulness of dynamic MRI with the turbo-FLASH technique in estimating myometrial invasion by endometrial carcinoma. Method: Forty six patients with endometrial carcinomas were evaluated with pathologic correlation. Dynamic MRI was performed with the rapid administration of Gd-DTPA using the turbo-FLASH technique. Results: The inner muscle layer showed more rapid contrast enhancement effects than the outer muscle layer even after menopause. Contrast-to-noise ratio between the inner muscle layer and endometrial carcinoma was maximum at ~50 s after administration of Gd-DTPA. In postmenopausal women, the accuracy in estimating myometrial invasion with T2-weighted images, contrast-enhanced T1- weighted images, and dynamic MRI was 66.7, 77.8, and 92.6%, respectively. Conclusion: Dynamic MRI with the turbo-FLASH technique is considered to be a useful imaging method for the estimation of myometrial invasion by endometrial carcinoma, especially in postmenopausal patients.
