The incidence rate of cerebrovascular diseases is increasing year by year, but the accuracy of clinical diagnosis is not high enough to cause disease. Many patients cannot effectively diagnose and treat the disease at the early stage. CT perfusion imaging (CTP) and CT angiography (CTA) were used to diagnose cerebrovascular diseases. In this paper, 26 cases of patients with acute cerebrovascular disease in our hospital from June to August 2020 were selected as the research objects. According to the diagnosis method voluntarily chosen by patients, 6 cases were only detected by CT perfusion imaging, 8 cases were only detected by CT angiography, and the remaining 12 cases were diagnosed by CT perfusion imaging and CT angiography. Then, according to the diagnosis results of the CT image of the patients with cerebrovascular disease, these samples were followed up after 3 months, 6 months, and 9 months, and more accurate diagnosis results were obtained. The study showed that, after 3 months of CT detection, the sensitivity of patients with CTP detection was 67%, that of patients with CTA detection was 72%, and that of patients with combined detection was 83%. After 6 months of CT detection, the sensitivity of patients with CTP detection was 75%, that of patients with CTA detection was 79%, and that of patients with combined detection was 93%. After 9 months of CT detection, the sensitivity of patients with CTP detection was 86%, that of patients with CTA detection was 89%, and that of patients with combined detection was 99%. Therefore, the use of CTA combined with CTP joint detection of acute cerebrovascular disease imaging technology can effectively improve the diagnostic accuracy of patients.
脑血管疾病的发病率逐年上升，但临床诊断的准确率还不够高，导致很多患者在疾病早期无法得到有效诊断和治疗。CT 灌注成像（CTP）和 CT 血管造影（CTA）被用于诊断脑血管疾病。本文选取我院 2020 年 6 月至 8 月收治的 26 例急性脑血管病患者为研究对象。根据患者自愿选择的诊断方法，6 例仅行 CTP 灌注成像检查，8 例仅行 CTA 检查，其余 12 例行 CTP 灌注成像和 CTA 联合检查。然后，根据脑血管病患者 CT 图像的诊断结果，对这些样本进行 3 个月、6 个月和 9 个月的随访，得出更准确的诊断结果。研究表明，CT 检测 3 个月后，CTP 检测患者的灵敏度为 67%，CTA 检测患者的灵敏度为 72%，联合检测患者的灵敏度为 83%。CT 检测 6 个月后，CTP 检测患者的灵敏度为 75%，CTA 检测患者的灵敏度为 79%，联合检测患者的灵敏度为 93%。CT 检测 9 个月后，CTP 检测患者的灵敏度为 86%，CTA 检测患者的灵敏度为 89%，联合检测患者的灵敏度为 99%。因此，采用 CTA 联合 CTP 联合检测急性脑血管病成像技术可以有效提高患者的诊断准确率。
