MRI of Uterine Leiomyomas: Report of 15 Cases
Abstract:bjective: To evaluate the value of MRI in diagnosing uterine leiomyomas.Materials and Methods: 15 patients were examined by a 0.35T super conducted MR imaging system, T 1 and T 2 weighted imaging were performed on both axial and sagital planes. The MRI features of 35 lesions in 15 patients with uterine leiomyomas were analysed by comparison with surgical and pathological findings retrospectively.Results: 87.5% lesions can be found on MRI images, including 10 from sub serosa, 23 from myometrium and 2 from endometrium. The accuracy of MRI localization is 88.6%. The signal intensity of most tumors (33) on T 1WI is iso to hypo intensity, only 2 is hyper intensity; while the signal intensities of all lesions on T 2WI are hyper than skeletel muscles and lower than myometriums, the changing patterns (changes on different echos of T 2 weighted imagings) are similar to that of skeletel muscles.Conclusion: MRI is a cha racteristic and the best methods for the diagnosis of uterine leiomyomas.
