目的探讨低场MRI对子宫腺肌症的诊断价值。方法回顾分析14例经手术病理证实的子宫腺肌症的低场MRI影像表现。结果14例中,弥漫性子宫腺肌症2例,表现为子宫体积增大呈类球形,T2WI子宫结合带弥漫性增厚,厚度13.2～35.0mm,平均16.5mm,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;其中1例患者T1WI与T2WI均可见散在点状高信号灶。局限性子宫腺肌症12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。结论低场MRI对子宫腺肌症诊断有重要价值,MRI表现具有特征性,能对子宫腺肌症作出明确诊断。
Objective To investigate the diagnostic value of low field MRI in adenomyosis. Methods Retrospective analysis of 14 cases of pathologically confirmed adenomyosis low field MRI image performance. Results In 14 cases, diffuse adenomyosis was found in 2 cases. The appearance of the uterus enlarged like a sphere. The thickness of T2WI uterine junction was diffusely thicker, with a thickness of 13.2-35.0 mm (average 16.5 mm) Clear; on the T1WI showed equal signal on the T2WI showed equal or slightly lower signal mixed with scattered spot-like high-signal stove; one case of T1WI and T2WI are scattered spot-like high signal. Limitations of adenomyosis in 12 cases, the performance of the uterus at the bottom or the limitations of the increase in the corresponding parts of the thickening of the junction zone, and myometrial demarcation is not clear; in the T1WI showed a signal was slightly lower on T2WI signal lesions The signal can be uneven, the central part may have multiple high-point signal. Conclusion Low-field MRI has important value in the diagnosis of adenomyosis. The MRI features are characteristic and can make a definite diagnosis of adenomyosis.
