Cerebrovascular disease is increasing rapidly because of its high morbidity and high mortality, which is a serious threat to human health. For the early diagnosis and treatment of diseases, the CT vascular noise combined with high-resolution magnetic resonance angiography in acute cerebral apoplexy vascular disease is adopted. 150 patients with ischemic stroke were selected, which were admitted to the Department of Radiology, Huizhou Central People’s Hospital, from January 2020 to December 2020. All patients accepted digital subtraction angiography (DSA), magnetic resonance angiography (MRA), and CT angiography (CTA) examination. Results. There were 76 cases of aneurysm in DSA examination, accounting for 46%; 69 cases with pulsating stenosis, accounting for 50.67%; and 5 cases of moyamoya disease, accounting for 3.33%. The number and proportion of cases of the above diseases in MRA examination were (75, 69, 71; 53.33%, 45.67%, 4%), and those in CTA examination were (71, 76, 3, 47.33%, 50.67%, 2%). Relative to the DSA gold standard, the sensitivity, specificity, and false positive rate of MRA were 81.51%, 95.19%, and 2.1, respectively, and those of CTA were 95.78%, 79.17%, and 11.0, respectively. The number of cases and accuracy of detection of cerebral aneurysms by MRA were (75, 96.57%), and those by CTA were (71, 91.2%), which was not statistically considerable, . For the number of cases and the detection accuracy of cerebrovascular malformations, MRA was (38, 92.68%) and CTA was (37, 90.24%), which was not statistically considerable, . Conclusion. The detection sensitivity and accuracy of MRA were better than those of CTA, while specific CTA was superior to MRA. The differences between the two detections were substantial (), while the sensitivity and false positive rate were not remarkably different (). Therefore, the combination of the two detections was of great significance to the diagnosis and treatment of stroke and other vascular diseases.

CT血管造影联合高分辨率磁共振血管造影对急性脑卒中血管病变的诊断价值

脑血管疾病因其发病率高、死亡率高而迅速增加，严重威胁人类健康。对于疾病的早期诊断和治疗，急性脑卒中血管病采用CT血管噪声结合高分辨率磁共振血管造影。选取2020年1月至2020年12月惠州市中心人民医院放射科收治的缺血性脑卒中患者150例。所有患者均接受了数字减影血管造影（DSA）、磁共振血管造影（MRA）和CT血管造影（ CTA) 考试。结果. DSA检查动脉瘤76例，占46%；搏动性狭窄69例，占50.67%；烟雾病5例，占3.33%。MRA检查中上述疾病的病例数和比例分别为（75、69、71；53.33%、45.67%、4%），CTA检查的病例数和比例分别为（71、76、3、47.33%、50.67%、 2%）。相对于DSA金标准，MRA的敏感性、特异性和假阳性率分别为81.51%、95.19%和2.1，CTA分别为95.78%、79.17%和11.0。MRA检测脑动脉瘤的病例数和准确率为（75, 96.57%），CTA为（71, 91.2%），在统计学上不显着，. 对于脑血管畸形的病例数和检测准确率，MRA为（38, 92.68%），CTA为（37, 90.24%），在统计学上并不显着，. 结论。MRA的检测灵敏度和准确度优于CTA，而特异性CTA优于MRA。两次检测之间的差异很大（)，而灵敏度和误报率没有显着差异(）。因此，两者结合检测对脑卒中等血管疾病的诊治具有重要意义。
