急性缺血性脑卒中ct灌注显像与临床表现的关系
目的 探讨CT灌注成像(CTP)对缺血性卒中急性期的诊断价值,并观察影像学检查与临床的相关性. 方法 31例急性半球梗死者在发病24 h内行头颅CT和CTP检查,同时进行美国国立卫生院神经功能缺损评分(NIHSS),其中18例在发病后12~72 h内行头颅MRI+弥散成像(DWI), 25例于发病后14~80 d复查CT,同时进行NIHSS评分. 结果 24 h内CT和CTP诊断敏感度分别为25.8%和90.3%, 6 h内CTP诊断敏感度88.2%.DWI上高信号的范围与局部脑血容量(CBV)的缺损程度间有相关关系;最初NIHSS评分与灌注缺损面积及灌注缺损程度无相关关系,而最终NIHSS评分与DWI异常面积和梗死面积有相关关系. 结论 CTP对超早期半球缺血有诊断价值,能发现缺血半暗带,可成为急性半球缺血的常规检查.最终的神经功能缺损与DWI异常面积和最后梗死面积相关。
