目的:探究减影CTA血管成像技术应用于颅内血管疾病的临床诊断的作用。方法:随机抽取210例经佛山市南海区第三人民医院初步诊断为头部动脉血管病变的患者经CT血管造影检查后,分别采用传统CTA重建(对照组)和减影CTA重建(观察组)方式,利用盲法来分析两组图像质量并诊断。结果:观察组总体上临床作用明显优于对照组,差异具有统计学意义(P<0.05)。结论:减影CTA技术有着较高的安全性、无创性、方便性等特点,能够较为形象地显示颅内动脉血管的病况,是一种准确率较高的诊断技术。
Objective: To investigate the clinical application of subtracting CTA angiography in the diagnosis of intracranial vascular diseases. Methods: Totally 210 patients who were diagnosed as head artery disease by the Third People ’s Hospital of Nanhai District of Foshan City were randomly selected by CT angiography and reconstructed by conventional CTA (control group) and CTA (observation group) Way, using blind method to analyze two groups of image quality and diagnosis. Results: The overall clinical effect of observation group was better than that of control group, the difference was statistically significant (P <0.05). Conclusion: Subtraction CTA has the characteristics of high safety, non-invasiveness and convenience. It can display the status of intracranial arterial blood vessels more vividly and is a diagnostic technique with higher accuracy.
