【摘要】 目的 探查SPECT脑血流灌注显像和CT、MRI脑显像在脑损伤后症候群患者中的应用价值。方法 126例有脑损伤后症候群的患者均用^99mTc-ECD行SPECT脑血流灌注显像;同时,其中80例行CT显像,其余46例行MRI显像。结果 126例患者中,SPECT检查阳性113例,阳性率为89.7％;CT和MRI检查阳性52例,阳性率为41.3％,二者差异明显（P<0.01）。结论SPECT脑血流灌注显像检查脑损伤后症候群的灵敏度高于CT或MRI,而CT或MRI在定位和微小病灶探查立优于SPECT,临床运用中应进行有机地结合。更多还原

【Abstract】 Objective To explore the application value of brain blood flow perfusion imaging with SPECT and that ofbrain imaging with CT and MRI. Methods 126 patients of posttraumatic brain syndrome were detected by brain blood flow perfusion imaging of SPECT with 99mTc-ECD. 80 cases of them examined simultaneously by CT scanning and the remainder 46 cases by MR imaging. Results There were 113 cases of the positive findings by SPECT with positive ratio of 89.7 percent, while 52 cases of positive findings by CT scan and MR imaging existed with positive ratio of 41.3 percent, a significant difference between them (P<0.01).The positve ratio of MRI was 63.0 percent and that of CT scan 28.8 percent. Conclusion Brain blood flow perfusion of SPECT is more sensitive than brain CT scanning or MR imaging in detecting the posttraumatic brain syndrome.However,CT and MRI are superior to SPECT in the brain location of small lesions.更多还原
