Abstract:
Objective To investigate the MR features of uterine leiomyomas and evaluate its diagnostic value. Methods Twenty six patients with probable uterine leiomyomas underwent preoperative ultrasound, T 1 weighted spin echo and T 2 weighted fast spin echo MR examinations. Among them, 11 cases were performed with dynamic contrast enhancement. Comparative analysis between MRI findings and pathologic results was done. Results MRI diagnosis in all cases was consistent with the results given by surgery and pathology, except 2 being pathologically proven as endometrial polyp or inflammatory pseudoplasma. The diagnostic accuracy of MRI was 92%, while the accuracy of ultrasound was 85%. The difference between the number of lesions detected by two modalities had statistical significance (89% for MRI vs 69% for ultrasound, ? 2=17.86, P
