MRI Features and Diagnostic Value in Adenomyosis / 实用放射学杂志

ABSTRACT

Objective To analyze MRI features and diagnostic value in adenomyosis.Methods Clinical and MRI data of 31 cases of adenomyosis confirmed by pathology were retrospectively analyzed.Turbo FSE T2WI,SE T1WI,and sagittal Turbo FSE T2WI examination were performed in all cases,10 of them were added to anatomic and sagittal fat-suppression(FS) T2WI scan.MR features of adenomyosis were analysed.Results In 19 cases of diffuse uterine adenomyosis,11 cases mainly showed diffusely thichened junctional zone of posterior wall.12 cases were focal uterine adenomyosis,the lesions located at posterior wall in 7 cases,front wall in 4 cases and bottom part in 1 case.28 cases displayed hypointensive masses like the intensity of junctional zone on T2WI and vesicular hyperintensive foci were found within the hypointensive lesions.The lesions in 21 cases were similar to that of myometrium on T1WI,9 of them displayed vesicular hyperintensive foci.Focal round-like junctional zone low signal intensity lesion in myometrial layer was found in 3 cases.Conclusion MRI can clearly determine the size and site of adenomyosis.FS is the valuable examination way.
