| 目的分析肝海绵状血管瘤的MRI表现并探讨最佳扫描方案。方法收集28例经MRI诊断的肝海绵状血管瘤,分析其MRI表现。男16例,女12例,年龄36～68岁。均无明显临床症状。MRI用0.5T超导型机,常规T1加权及T2加权扫描后,再行重T2加权成像,TR=4000～6000ms,TE=140～180ms.18例行Gd DTPA增强扫描,9例为动态增强扫描。结果多发病灶12例,单发16例。瘤体在SET1加权像上呈低信号,在T2加权像上呈明显高信号,在重T2加权像上亦呈明显高信号,边缘均清楚锐利。 |

| Purpose To analyse MRI manifestations of cavernous hemangioma of liver and discuss proper MR pulse sequences. Methods 28 cases of cavernous hemangioma of liver diagnosed by MRI were analysed. There were 16 male and 12 female patients. The age ranged from 36 to 68 years. MR Scan was performed on a 0.5T superconducting imager. Heavily T2 weighted images (TR/TE=4000～6000ms/120～180ms) were obtained after routine T1WI and T2WI sequeuces. Gd DTPA contrast enhanced scan was performed in 18 cases including 9 dymamic scan. Results There were 12 cases with multiple lesion and 16 cases with single lesion. The tumor appeared hypointense on T1WI and markedly hyperintense on T2WI, it still appeared markedly hyperintense on heavily T2WI.The margins of tumor were clear and sharp. On enhanced scan, the lesion showed obvious and lasting enhancement. Centripetal progressive enhancement was found in cases with larger lesion.Conclusion Heavily T2WI and Gd DTPA contrast enhanced scan were diagnostic for cavernous hemangioma of liver. |
