目的探讨子宫腺肌病的MRI表现及MRI扫描的诊断价值。方法对19例经手术病理证实的子宫腺肌症患者行MRI检查并回顾性分析。结果19例中,弥漫性子宫腺肌症11例,子宫壁结合带弥漫性增厚,结合带与肌层分界不清;在T1WI上表现为等信号,在T2WI上表现为等或略低信号,混杂有散在多发点状高信号灶。局限性子宫腺肌症8例,表现为子宫体部或底部局限性增大,相应部位结合带增厚,与肌层分界不清,在T1WI上呈等信号,T2WI上呈略低信号,病灶信号可不均匀,中央部可有多发点状高信号。结论MRI能对子宫腺肌症作出明确诊断,矢状位T2WI是显示病变的最佳扫描序列。
Objective To investigate the MRI findings of adenomyosis and the diagnostic value of MRI. Methods Nineteen patients with pathologically confirmed adenomyosis underwent MRI examination and retrospective analysis. Results In 19 cases, diffuse adenomyosis was found in 11 cases, diffuse thickening of the uterine wall junction band, unclear boundary between the junctional band and the muscular layer, equal signal on T1WI and equal or slightly lower signal on T2WI , Mixed with scattered spot-like high signal stove. Limitations of adenomyosis in 8 cases, showing the limitations of the uterus or the bottom of the body increased, the corresponding part of the thickening of the junction zone, and myometrial demarcation between the was showed on the T1WI equal signal was slightly lower signal on T2WI lesions The signal can be uneven, the central part may have multiple high-point signal. Conclusion MRI can make a definite diagnosis of adenomyosis, and the sagittal T2WI is the best scanning sequence to display the lesions.
