| 目的 分析子宫腺肌病的MRI 和DSA 特征,提高对其影像学表现的认识。方法 27 例子宫腺肌病, TUAE 术前行MRI 和DSA 检查。MRI 检查采用SE T1 、Tubor-SE T2WI 和SE T1WI 增强成像,造影剂为Gd-DTPA ,剂量0. 1mmol/ kg 体重,对不同成像序列的MR 信号及相关特征进行分析。双侧子宫动脉超选造影,对不同时相的DSA 表现进行分析。结果 27 例子宫体积均有增大,19 例结合带为局限性或弥漫性增厚,平均(36. 11 ±10. 50) mm ,子宫腺肌瘤8 例,体积大小平均为(155. 70 ±81. 86) mm3 ,85 %的病例在低信号病变内出现高信号灶( T2WI) ,有明显强化。27 例腺肌病子宫动脉分支均有不同程度增粗、增多、延长,9 例有增生血管,与纡曲、增粗的螺旋动脉同时参与供血。结论 子宫腺肌病具有典型的MRI 和DSA 征象,常规MRI 能够做出明确的诊断,DSA 则能够为其诊断提供更多的信息。 |

| Objective To analyze the MRI and DSA feature of uterine adenomyosis , and further understand it simaging apperance. Methods MR imaging and DSA were performed in 27 cases of uterine adenomyosis before TUAE. MR imagingconsisted of T1-weighted spin-echo sequence obtained before and af ter cont rast material administ ration (0. 1 mmol/ kg of bodyweight of gadolinium dimeglumine) , T2-weighted Turbo spin-echo sequences. On different sequence , MRI signal intensityand relative features of the adenomyosis were analyzed. Superselective angiography was performed in bilateral uterine arteryand the DSA appearances in different periods of time were analyzed. Results All the 27 cases showed uterine enlargment .The junctional zone thickened focally or diffusely in 19 cases , the average thickness was (36. 11 ±10. 50) mm. Eight casesshowed adenomyoma with the average volume of (155. 70 ±81. 86) mm3 . Bright foci , which indicated the vivid enhancement , was seen in the abnormal fields of low signal intensity on T2-weighted images in about 85 % of paients. Uterine arteriograms in 27 cases showed spiral arteries enlarged and lengthened in different degrees. Neogenetic arteries , which providedthe blood supply together with the enlarged and sinuous arteries simultaneously , were found in 9 adenmomyoma caes. Conclusion Both typical MRI and DSA fetures were found in adenomyosis patient s. Definite diagnosis can be made based on theconventional MR imaging , and DSA can provide more useful information for the diagnosis. |
