摘要
目的:总结顺磁造影在脑转移瘤诊断中的重要价值。材料和方法:脑转移瘤30例,均经病理和临床证实,全部病例均做了GD-DTPA顺磁造影。使用03T永磁MR仪,做常规平扫及造影扫描。结果:脑转移灶单发14例,多发16例,其中发生在幕上24例,幕下6例,兼有2例。病灶最大径02～7cm,平均28cm。发现病灶数:T1WI44个,T2WI54个,顺磁造影为124个。结论:顺磁造影发现的脑转移瘤病灶明显多于非增强MRI,并且能分清病灶与瘤周水肿的界限,从而明确其发生的部位、数目、形态和大小,结合其临床和影像学特征,容易作出正确诊断。
Objective:To summarize the important value of contrast enhancement MRI in cerebral metastasis.Materials and Methods:30 cases of cerebral metastasis which were confirmed by pathology and clinical diagnosis;The contrast enhancement MRI were taken in all of those cases.The 0 3T permanent magnet MRI system was used in this study.Results:There were single metastasis 14 cases,multiple metastasis 16 cases;The largest diameter is from 0.2cm to 7cm averaging 2.8cm.The appearance of tumor is 44 tumors by T1WI,54 tumors by T2WI,124 tumors by contrast enhancement MRI.Conclusion:Contrast enhancement MRI is ahead of noncontrast MRI and have high value to diagnose the surrounding edema,position,shape,size and number of the tumors.
