目的分析64排螺旋CT在神经系统疾病诊断中的优势。方法以90例确诊神经系统疾病患者作为研究对象,48例行头部常规扫描,28例行数字减影血管造影联合行头颈内CT血管造影(CTA),14例行脑灌注成像,均行脑电图与64排螺旋CT,就脑电图与64排螺旋CT诊断符合率及不同检查方式的效果进行比较。结果 64排螺旋CT诊断脑血管病符合率、合计符合率高于脑电图,差异均具有统计学意义(P<0.05);64排螺旋CT诊断神脑血管病、颅内占位性病变、帕金森病、偏头痛,均达到100%;相较于其他震荡技术,64排螺旋CT颅后窝骨伪影显示率更高,图像清晰,不受扫描角度影响(14 VS12),多发血管瘤、畸形病灶检出率高(3 VS 2),对动脉狭窄显示更清晰,可发现活动性斑块(2 VS 0),可快速测定脑灌注血流速度,敏感度较高,耗时更短。结论 64排螺旋CT是诊断神经系统疾病,特别是颅内器质性疾病、循环障碍相关疾病的重要技术,对于炎症、神经元相关病变也有一定诊断价值。
Objective To analyze the advantages of 64-slice spiral CT in the diagnosis of neurological diseases. Methods Totally 90 patients with diagnosed neurological diseases were enrolled in this study. 48 patients underwent routine brain scans, 28 underwent digital subtraction angiography (CTA) and 14 cerebral perfusion imaging Electrocardiogram and 64-slice spiral CT, EEG and 64-slice spiral CT diagnosis of coincidence rate and the effect of different examination methods were compared. Results 64-slice spiral CT diagnosis of cerebrovascular disease coincidence rate, the total coincidence rate higher than that of EEG, the difference was statistically significant (P <0.05); 64-slice spiral CT diagnosis of cerebrovascular disease, intracranial space-occupying lesions, Parkinson’s disease and migraine, all achieved 100%. Compared with other concussion techniques, 64-slice spiral CT posterior cranial fossa artifact showed a higher rate, clear images, not affected by the scan angle (14 VS12), multiple hemangiomas , A high detection rate of deformity lesions (3 VS 2), the stenosis of the arteries showed clearer, found active plaques (2 VS 0), rapid determination of cerebral perfusion blood flow velocity, high sensitivity, shorter time-consuming . Conclusion 64-slice spiral CT is an important technique for the diagnosis of neurological diseases, especially intracranial organic diseases and circulatory disorders. It also has certain diagnostic value for inflammation and neuron-related diseases.
