摘要
目的探讨联合应用CT灌注成像(CTP)和CT血管造影(CTA)技术对急性缺血性脑血管病(CVD)的临床诊断价值。方法20例临床怀疑急性CVD的患者进行CTP联合CTA扫描检查,扫描结束后,经CT灌注软件和3D血管软件进行评估。结果16例CTP检查发现脑梗死前期低灌注,其中13例位于大脑中动脉供血区,CTA检查13例中有11例可见相应责任血管的不同程度的狭窄,并结合CTA原始图像可准确的评估血管狭窄程度,其余3例位于大脑后动脉供血区,CTA未检出狭窄。4例患者检查未见明显异常。结论CTP及CTA联合应用于急性缺血性脑血管病的技术是值得推广的一项影像学检查新方法。
Objective To study the clinical diagnosis value of the combination application of CT perfusion（CTP） and CT angiography （CTA） in cerebrovaseular diseases. Methods 20 patients suspected of cerebrovascular diseases（CVD） were examined with CTP and CTA. All the CTA data were send to 3D post processing card for MIP, SSD and VR reconstruction. Perfusion data were analyzed by CT perfusion package. The absolute TTP, MTT, CBV, CBF values and the relative value between normal and pathological sides were calculated. Results Low perfusion which indicated the prophase of isehemia infarction were detected in 15 cases, 12 cases were located in MCA area, and 10 of them the stenosis of responsible arteries were demonstrated. The degree of the vessel stenosis can be evaluated exactly by CTA source images. Other 5 cases were located in the area of PCA and no positive detection in CTA examination. Conclusion Combined application of CTP and CTA can finish two examinations at the same time in the fast and economic way. Both the hemodynamics changing and the morphology of the vessels were demonstrated which providing omnidirectional
