目的：探讨神经外科术后患者颅脑感染CT和MRI的诊断价值及对照研究。方法收集整理本院2009年1月至2012年12月神经外科颅脑手术后发生颅内感染的患者80例的临床资料，所有患者均进行西门子MRI、CT设备进行常规检查2～3次，分析对比MRI和CT分别对神经外科术后颅脑感染者诊断的准确率及不同发病阶段的诊断阳性率。结果 CT图像结果显示，正常图像41例（51.3%），异常图像39例（48.7%）；MRI图像结果显示，正常12例（15.0%），异常68例（85.5%）。MRI组图像诊断阳性率显著高于CT组，两组患者比较差异具有统计学意义（P均＜0.05）。CT组早期异常者32例（40.0%），后期异常者15例（18.8%）；MRI组早期异常者72例（90.0%），后期异常者18例（26.3%），MRI组对处于不同时期的颅脑损伤患者图像诊断阳性率显著高于CT组，两组患者比较差异具有统计学意义（P均＜0.05）。结论 CT及MRI对于神经外科术后患者颅脑感染的诊断有很大的帮助，同时MRI检查可以更好地协助颅脑感染者的诊断，提高患者的诊断阳性率。

Objective To investigate the diagnostic value of CT and MRI in patients with neurosurgical infection after brain infection. Methods Total of 80 patients after neurosurgery craniotomy intracranial infection were collected from January 2009 to December 2012 in our hospital. Siemens MRI and CT equipment for routine checks for 2-3 times;MRI, CT diagnostic accuracy, in respectively neurosurgical postoperative brain infection were done in the 80 cases and the characteristics of different stages were analyzed. Results The CT images showed that normal image were 41 (51.3%) cases, abnormal image were 39 (48.7%) cases. The MRI images showed that normal 12 (15.0%) cases, MRI abnormalities 68 (85.0%) cases. MRI imaging diagnostic yield was significantly higher than the CT group (P < 0.05). The early abnormalities and latter abnormalities in CT group were 32 (40.0%) cases and 15 (18.8%) cases respectively, they were all lower than the MRI group which were 72 (90.0%) cases and 18 (26.3%) cases, the diagnostic yield of MRI image at different periods of brain injured patients were significantly higher than the CT group (P<0.05). Conclusions CT and MRI could effectively diagnose brain infection for patients after neurosurgery, while MRI examination could better assist in the diagnosis of brain infection, improve the patient’s diagnostic yield.
