减影CTA联合常规CTA对脑血管病的诊断价值

Subtraction CTA Combined with Conventional CTA on Cerebrovascular Disease Diagnosis Value

目的评估16层螺旋CT减影血管成像(SCTA)联合常规CTA(CTA)的图像质量和在诊断脑血管病中的临床价值。方法对临床怀疑脑血管病的82例患者的影像资料进行回顾性分析,对SCTA和CTA图像质量进行比较,评价SCTA联合CTA对脑血管病的准确性进行评估。结果图像质量优秀占78%(64/82),好占12.2%(10/82),一般占7.3%(6/82),差占2.5%(2/82)。82例中,发现脑血管病36例,诊断准确性达94.1%。结论减影CTA(SCTA)联合常规CTA(CTA)的重组图像质量高,对脑血管病有较高的诊断价值。

Objective Evaluation 16 layer spiral CT subtraction vascular imaging （SCTA） combined with conventional CTA （CTA） image quality and in the diagnosis of the clinical value of cerebrovascular disease. Methods Clinical doubt cerebrovascular disease in 86 patients were retrospectively analysis, image data to SCTA and CTA image qnality evaluation, compared SCTA joint CTA to evaluate the accuracy of cerebrovascular disease. Results Image quality excellent accounted for 78% （64/82）, 12.2% （10/82）, 7.3% （6/82）, and generally poor 2.5% （2/82）, The 82 patients, found that cerebrovascular disease （36 cases） and diagnosis accuracy of 94. 1%. Conclusion Subtraction CTA （SCTA） combined with conventional CTA （CTA） the restructuring of the image quality is high, to have higher cerebrovascular disease diagnosis value.
