磁敏感加权成像在创伤性颅脑损伤中的应用与研究

摘要

目的 探讨高分辨率磁敏感加权成像(SWI)在创伤性颅脑损伤检查中的应用价值.方法 将近年来收治的创伤性颅脑损伤患者根据临床格拉斯哥昏迷评分(GCS)分为轻度及中重度脑外伤.所有患者行CT平扫、常规MRI(T2WI、FLAIR)和SWI检查,观察统计各方法 所示患者脑内病灶的数量、部位,并进行统计学分析和比较.结果 所有患者中,SWI共检出病灶数1 364个,FLAIR、T2WI、CT分别检出病灶数为827、564、204个,SWI检出病灶数高于其他各种检查,差异均有统计学意义(均P =0.000);从浅部、深部至后颅窝,SWI检出病灶数均高于其他各种检查,差异有统计学意义(P=0.000);SWI检出的病灶数与GCS评分有明显相关性(P=0.000).结论 SWI技术简便易行,在创伤性颅脑损伤检查中可以准确、客观地检测出颅内病灶的数目和部位,对评估损伤的严重程度有重要的补充价值,较常规MRI与CT平扫具有明显的优势.%Objective Of high-resolution susceptibility weighted imaging (SWI) examination in traumatic brain injury in the application. Methods Nearly years the traumatic head injury were based on clinical patients with a Glasgow coma scale (GCS) into mild and moderate to severe brain injury. All patients were done CT and regular MRI (T2WI, FLAIR) and SWI check, observation statistics each method shows the number of patients with brain lesions, site, and the statistical analysis and comparison. Results All patients, SWI lesions were detected a number 1364, FLAIR, T2WI, CT were detected lesions number is 827, 564, 204, SWI detection number higher than other all sorts of check lesions, the difference was statistically significant (P = 0.000); From shallow and deep to the posterior fossa , SWI detection lesions are higher than the number of other inspection, the difference was statistically significant.( P= 0.000); The number of lesions on SWI Was correlated with GCS score (P= 0.000). Conclusion SWI technology is very easy, in traumatic head injury in check, objectively can accurately detect the intracranial lesions and the number of parts, to evaluate the severity of the damage have important added value, compared with conventional CT and MRI has advantage.
