摘要
目的对比分析64排CTA技术与DSA血管成像,探讨64排螺旋CT在心血管疾病中的诊断价值。方法在我科行CTA冠脉成像患者中,随机选择57例患者的影像资料,与DSA介入血管造影对比,进行回顾性分析。结果 57例患者共191支血管,CTA发现102支冠状动脉狭窄,其中LAD38支,D122支,LCA17支,LMA15支,RCA10支。其中管腔狭窄>50%者89支,管腔狭窄>75%者47支,管腔完全闭塞者18支。CAG检查发现114支冠状动脉狭窄,LAD40支,D125支,LCA21支,LMA17支,RCA11支。其中管腔狭窄>50%者95支,管腔狭窄>75%者51支,管腔完全闭塞者18支。两者相比在各血管支狭窄及狭窄程度上CAG均较CTA检出率高,但是差异不显著,不具有统计学意义(P>0.05)。结论 64排螺旋CT作为一种无创性的影像诊断技术,提高了可疑冠心病患者的检出率,此检查有较高的诊断准确性,可作为评价、筛查冠状动脉狭窄的一种无创检查方法。
Objective Purpose Comparative analysis of 64 - slice CTA and DSA angiography techniques to explore the 64 - slice spiral CT in the diagnosis of cardiovascular diseases. Methods Randomly selected 57 patientsimage data in CTA Inspection, intervention angiography compared with DSA, retrospective analysis. Results 57 patients were 191 vessels, CTA found that 102 coronary artery stenosis, which LAD 38 arteries, D1 22 arteries, LCA 17 arteries, LMA 15 arteries, RCA 10 arteries, stenosis 〉 50% 89, stenosis 〉 75% were 47, lumen occlusion 18. CAG examination revealed 114 coronary artery stenosis, LAD 40 arteries, D1 25 arteries, LCA 21 arteries, LMA 17 arteries, RCA 11 arteries, stenosis 〉 50% 95, stenosis 〉 75% were 51 ,lumen occlusion 18. When comparing the two in the arteries narrow and the degree of stenosis on CTA CAG than detection rate, but the difference was not significant, was not statistically significant （ P 〉 0. 05 ）. Conclusion 64 - slice spiral CT as a noninvasivc diagnostic imaging technology to improve the detection rate of patients with suspected coronary artery disease, this check has a high diagnostic accuracy, as the evaluation, screening for coronary artery stenosis of a non-invasive screening method.
