本文搜集经组织学证实的１５例颅内转移瘤病例，采用Ｇｄ－ＤＴＰＡ增强和增强后磁化传递对比技术（ｍａｇｎｅｔｉｚａｔｉｏｎｔｒａｎｓｆｅｒｃｏｎｔｒａｓｔ，ＭＴＣ）相结合的方法，初步探讨了ＭＴＣ在检测脑转移瘤中的价值，发现：（１）ＭＴＣ在低磁场强度下对Ｇｄ－ＤＴＰＡ增强有协同作用；（２）两者结合可进一步发现和明确常规ＳＥ序列成像上没有或可疑的病灶，从而可提高检出率，防止漏检。
This article collected 15 cases of histologically confirmed intracranial metastases, the use of Gd-DTPA enhanced and enhanced magnetizationtransfercontrast (MTC) combination of methods to explore the value of MTC in the detection of brain metastases, The results showed that: (1) MTC had a synergistic effect on the enhancement of Gd-DTPA under low magnetic field strength; (2) The combination of the two could further detect and confirm the absence of or suspicious lesions on routine SE sequences, thereby improving the detection rate and preventing Missing inspection.
