Objective To make a thorough inquiry about the characteristics and diagnostic value of low-field MRI imaging in the diagnosis of uterine myoma. Methods Retrospective analysis of MRI data of 76 patients in our hospital with uterine fibroids identified by surgery from December 2014 to January 2016. And the distribution, enhancement degree and type of the malignant transformation of the patients were analyzed and classified. Results In 76 cases, the patients with muscle wall fibroids patients accounted for 39.5% of the total, the type of film account for 39.5% and the number of submucosal myoma accounted for 21.1% of the total. The image of MRI scanning display that the signals of T1 weighted is isointense. And then the signals of T2 weighted is low. The signal is less uniform and the boundary is fuzzy. And the size is 5.7×4.5×7.4cm. In enhanced scan, the lesions in the anterior wall of the uterus increased obviously, and the boundary was not clear, and the degree of enhancement of the lesion was less than that of the surrounding normal muscle wall. The results confirmed by pathology shows that the total detetion rate of the patients with uterine myoma is 90% or more. Conclusion In the judging the patients with uterine myoma, MRI scanning and enhanced scan can give accurate location, thus it can be used in the field of uterine myoma detection for further promotion and application.
