多层螺旋CT诊断冠状动脉狭窄的准确性探讨

Accuracy of Multi-slice Spiral CT in Diagnosis of Coronary Artery Stenosis

目的探讨多层螺旋CT诊断在冠状动脉狭窄准确性的临床疗效。方法选择2016年11月—2018年1月到我院检查的冠状动脉狭窄患者72例作为研究对象。所有研究对象均进行多层螺旋CT成像、冠脉造影检查,结果以CAG为金标准,对图像结果进行狭窄程度评价。结果 72例冠状动脉狭窄患者均经冠状动脉造影检查最终确诊,确诊前所有患者均行多层螺旋CT检查,最终确诊70例,与冠状动脉造影检查诊断符合率为97.22%,与金标准比较,差异无统计学意义(P> 0.05);冠状动脉造影检查患者中,轻度狭窄34例,中度狭窄34例,重度狭窄4例;多层螺旋CT检查无狭窄、轻度狭窄、中度狭窄及重度狭窄率比较,差异均无统计学意义(P> 0.05)。结论将多层螺旋CT用于冠心病的患者检查中能对疾病做出早期诊断且准确性高,能有效检查出患者的病变情况,具有较大应用价值。

Objective To investigate the clinical efficacy and safety of multi-slice spiral CT in the diagnosis of coronary artery stenosis.Methods 72 patients with coronary artery stenosis who were examined in our hospital from November 2016 to January 2018 were selected as the study subjects. All the subjects underwent multi-slice spiral CT imaging and coronary angiography.The results were evaluated with CAG as the gold standard. Results 72 patients with coronary artery stenosis were finally diagnosed by coronary angiography.Before diagnosis,all patients underwent multi-slice spiral CT examination.70 patients were finally diagnosed.The coincidence rate with coronary angiography was 97.22%.There was no significant difference compared with gold standard (P>0.05).There were 34 cases of mild stenosis,34 cases of moderate stenosis and 4 cases of severe stenosis in coronary angiography.There was no significant difference in the rates of no stenosis,mild stenosis,moderate stenosis and severe stenosis in multislice spiral CT (P>0.05).Conclusion Multi-slice spiral CT can be used for the diagnosis of patients with coronary heart disease.It can diagnose the disease early and has high accuracy.It can effectively detect the lesions of patients,and the coincidence rate and accuracy are good.Effectively check the patient's lesions.
