摘　　要：目的:分析子宫腺肌症离体标本的低场MRI表现,探讨子宫腺肌症的低场MRI诊断。材料和方法:采用OUT-LOOK PROVIEW 0.23TMR对17例子宫腺肌症离体标本行采用矢状位T1WI、T2WI及irT2WI平扫并与病理进行对照分析。结果:子宫体积增大呈类球形,结合带增厚,厚度为10.4～28.6mm,平均15.2mm。病变主要位于子宫后壁肌层14例和前壁3例。所有标本T2WI与irT2WI示子宫肌层内低信号区内夹杂斑片状高信号影,T1WI示子宫肌层内散在斑点状低信号影,6例标本肌层内少许斑点状高信号。T2WI/irT2WI呈高信号而T1WI呈低信号的病理上为异位的内膜岛,在T2WI与T1WI均呈高信号的为异位内膜出血灶。结论:低场MRI对子宫腺肌症诊断有重要价值,其能真实有效的反映出病变的病理特征,T2WI与irT2WI是病灶显示的敏感序列。Purpose： To analyze the MRI findings of isolated specimen of uterine adenomysis and its histopathologic basis. To investigate the MRI diagnosis of uterine adenomyosis. Materials and Methods： 17 isolated specimens of uterine adenomyosis were scanned by 0.23T MR made in PHILIPS. The sequences included saggital T1WI, T2WI and inversion recovery T2WI（irT2WI）. Results： The volume of uterines increased and shapes were lobular. The conjugation zones became thicker. The range was from 10.4mm to 28. 6mm and means 15.2mm. The foci located in the posterior wall of uterines in 14 specimens and 3 in the anterior walls. Diffuse hyperintensive loci distributed over the areas of decreased signal intensity in myometrium of all the specimens on T2WI and irT2WI. Many hyporintensive foei were found in all specimens on T1WI and slightly hyperintense foci in 6 specimens on T1WI. The hyperintense foci shown on T2WI or irT2WI and hypointense foci on T1WI corresponded to the heterotopic endometrial islands without hemorrhage. The hypointense loci shown on both T2WI and T1WI were the beterotopic endometrial islands with hemorrhage. Conclusions： Low field MRI is very useful techniques for the diagnosis of adenomyosis and reflect the histopathologic features. T2WI and irT2WI are much sensitive sequences.
