MSCT、MRI对肝肾错构瘤的诊断价值

MSCT,MRI HAMARTOMA OF THE LIVER AND KIDNEY IN THE DIAGNOSIS

目的:研究动态CT增强扫描对错构瘤的定性价值。方法:随机选择11例错构瘤患者,先行薄层扫描(3.0～5.0mm)平扫,再静脉注入对比剂(优维显)100mL后,对其进行动态扫描。结果:CT平扫肿瘤内部见钙化及脂肪密度(CT值为-90左右)及软组织密度,CT增强后脂肪部分无变化,软组织部分明显强化,在MR上T1、T2均表现混杂密度信号,行脂肪抑制技术信号明显减弱。结论:动态CT增强及MRI对错构瘤的鉴别诊断有较高价值。

Objective： To study the dynamic enhanced CT scan of the right or wrong angiomyolipomar qualitative value. Methods： 11 cases of hematoma patients at random,the first step is to take,TLC （3.0 - 5.0mm） scan thesecond step take,intravenous injection of contrast medium（Ultravist） 100mL, the last step is to have their dynamic scan. Results ：The CT scan sees calcification within the tumor and fat density（ CT value of about - 90） and soft tissue density, CT enhanced after the fat part of the change, some of the soft tissue sig- nificantly enhanced MR in the T1 ,T2 showed mixed signal intensity, the fat Suppression significantly weakened signal. Conclusion：Dynatmic enhanced CT and MRI right or wrong in the differential diagnosis hamartoma of a higher value.
