【摘要】 目的探讨超薄多层螺旋CT和脑灌注成像在急性颅脑外伤(TBI)早期诊断中的临床应用价值。方法收集2010年12月~2012年10月我院收治的200例急性颅脑外伤患者检查资料,均于伤后6 h内行超薄多层螺旋CT(MSCT)和CT脑灌注成像(CTP)检查,全部病例于伤后2~3 d动态复查MSCT明确诊断,将数据进行回顾性分析,采用卡方检验评价。结果在MSCT与CTP这两种检测方法中,CTP在脑挫裂伤、硬膜下血肿和脑内血肿的诊断中优于超薄MSCT(P<0.05),并且病灶周围低灌注区域大于超薄MSCT。结论 CTP对于急性颅脑外伤早期和微小损伤的诊断优于超薄MSCT,同时可以反映脑组织的灌注情况,具有可靠的临床价值。更多还原

【Abstract】 Objectives To discuss the value of ultrathin multi-slice spiral CT and perfusion imaging in traumatic brain injury( TBI). Methods The clinical data of 200 patients with traumatic brain injury during December 2010 to October 2012,both in 6 hours after injury within conventional ultrathin multi-slice spiral CT( MSCT) and computed tomographic perfusion( CTP),all the cases in2 to 7 days after injury dynamic review of conventional ultrathin multilayer spiral CT or MR,were analyzed retrospectively. Results Between ultrathin multi-slice spiral CT and CTP checking methods,CTP in cerebral contusion and laceration,subdural hematoma and intracerebral hematoma associated with intracerebral hematoma in the diagnosis with statistical difference,better than the ultrathin multi-slice spiral CT( P < 0. 05),and the Hypo-perfusion area around focus was bigger than Ultra-thin MSCT. Conlusion CTP has better diagnosis in early acute traumatic brain injury and small damage,rather than the ultrathin MSCT diagnosis,with response to the perfusion situation of brain tissue at the same time,has reliable clinical value.更多还原
