[摘要]意图 比较颅脑多排螺旋CT(MSCT)和CT腦灌注成像(CTPI)在外伤性充满脑肿胀(DBS)中的运用作用。办法 选取2015年1月~2016年10月收治的100例DBS患者作为研讨目标,运用GE light speed 64排螺旋CT机扫描,在伤后2~6 h熟行惯例MSCT查看和CTPI查看,72 h内再次复查CTPI。比较MSCT与CTPI的DBS检出率,剖析脑血流量(CBF)、脑血容量(CBV)、均匀经过时刻(MTT)和超清五颜六色图画与DBS预后的联系。成果 MSCT对DBS的检出率为88.0%,低于CTPI的96.0%(P<0.01)。医治后,患者的CBF、CBV呈升高趋势,初度查看与复查CBF、CBV、MTT值比较,差异有统计学含义(P<0.01)。定论 MSCT和CTPI在DBS中具有较好的运用作用,但CTPI可以有用点评患者的预后状况,经过超前五颜六色图画可直观查询和点评患者的病况改变,值得在临床中推广运用。

[Abstract]Objective To compare the application effect of brain multi-slice spiral CT (MSCT) and CT perfusion imaging (CTPI) in evaluation of traumatic diffuse brain swelling (DBS).Methods Altogether 100 cases of patients with DBS from January 2015 to October 2016 were selected as study object.All the patients were scanned by using GE light speed 64-slice spiral CT machine and underwent conventional MSCT and CTPI examinations at 2 to 6 hours after injury and CTPI re-examinations within 72 hours.The detection rate of DBS by using MSCT and CTPI were compared,cerebral blood flow (CBF),cerebral blood volume (CBV),mean transit time (MTT) and the relationship between ultra clear color images and prognosis of DBS were analyzed.Results The detection rate of DBS by using MSCT was 88.0%,significantly lower than that of CTPI (96.0%)(P<0.01);after treatment,CBF and CBV was increased,while MTT was decreased,the difference of CBF,CBV and MTT between initial examination and reexamination was statistically significant (P<0.01).Conclusion MSCT and CTPI have good application effect in evaluation of DBS,but CTPI can effectively assess the prognosis of patients.By using the color image,disease change can be directly evaluated and observed,which is worthy of clinical application.

跟着我国现代化进程的高速开展,各类工业和交通事故等导致的人身损伤逐年增多,仅颅脑外伤(traumatic brain injury,TBI)的发生率>100/10万[1]。TBI的特点是重型脑外伤逐年增多,充满性脑损伤(diffuse brain injury,DBI)是TBI常见的急症之一[2]。它可独自存在或与各种类型的TBI一起并存,因为DBI的医治困难,死亡率>60%,预后极差,也是影响重型TBI预后的重要因素之一[3]。因而,本次研讨旨在研讨多排螺旋(Multi-slice spiral CT,MSCT)和CT脑灌注成像(computed tomographic perfusion imaging,CTPI)在外伤性充满脑肿胀(diffuse brain swelling,DBS)中的运用价值,为DBS患者前期确诊和医治计划的挑选以及预后判别供给牢靠根据,找到一种“金规范”,为重型TBI的确诊供给一种新的思路和办法,现报导如下。
