摘　　要：目的 研究单心跳心脏成像技术与血管内超声(IVUS)鉴别诊断冠脉狭窄和斑块性质的临床价值。方法 选取2022年7月到2023年3月我院冠心病患者96例,入院后先行256排CT检查,在一个月内行IVUS检查。以IVUS检查结果作为标准,比较两种检查方式对冠脉狭窄程度评估;分析IVUS与CT对斑块面积/管腔重构指数/偏心指数的相关性,IVUS与CT对斑块性质的相关性。结果 96例患者共评估1144个节段,324个狭窄, IVUS显示无狭窄、轻、中、重度狭窄分别为24例、108例、148例、44例,CT成像分别显示4例、112例、 152例、56例。两种检查方式对冠脉狭窄程度判断无统计学意义(P>0.05),所示的冠脉狭窄程度呈正相关(r=0.426)。两种检查方式的平均斑块面积、血管重构指数与斑块偏心指数比较,无统计学意义(P>0.05)。IVUS在324个病灶斑块中显示112个软斑块、124个纤维斑块、88个钙化斑块,单心跳心脏CT显示116个软斑块、140个纤维斑块、68个钙化斑块。两种检查方式在辨别冠脉斑块成分上无统计学意义(P>0.05),显示的斑块成分呈正相关(r=0.712)。结论 单心跳心脏成像技术对冠脉狭窄程度的检查结果准确性较高,反映病变血管内部情况,IVUS与斑块偏心、对血管重构及冠脉斑块性质的诊断结果具有相关性,可作为高危人群筛查首选方式。Objective To evaluate the clinical value of single heartbeat cardiac imaging with intravascular ultrasound(IVUS)for the differential diagnosis of stenosis a nd plaque of coronary arteries.Methods Ninety-six patients with coronary artery disease from July 2022 to March 2023 were selected.All patients underwent volumetric 256-row computed tomography(CT)examinations after admission and IVUS examination within one month of admission.With the IVUS findings as the standard,the two examination modalities were compared for the assessment of the degree of coronary stenosis.Parameters lesions including plaque area,reconstruction index and eccentricity index were measured and compared under CT.Then the correlation with the property of carotid plaque and the IVUS was discussed.Results A total of 1,144 segments were assessed in 96 patients,and the stenosis was considered in 324 segments.IVUS revealed no,mild,moderate,and severe stenosis in 24,108,148,44 patients,and CT imaging showed no stenosis in 4 cases,mild stenosis in 112 cases,moderate stenosis in 152 cases,and severe stenosis in 56 cases.The assessment of the coronary stenosis degree yielded no statistical difference between two examination modalities(P>0.05).The degree of coronary artery stenosis showed a positive correlation between the two examination methods(r=0.426).The plaque area,reconstruction index and eccentricity index demonstrated in two examination modalities showed no statistical difference(P>0.05).IVUS showed 112 soft plaques,124 fibrous plaques,88calcified plaques in 324 lesions.The single heartbeat cardiac imaging showed 116 soft plaques,140 fibrous plaques,and 68 calcified plaques.The property of carotid plaque shown in two two examination modalities showed no statistical difference(P>0.05).The plaque components shown in two examination modalities were positively correlated(r=0.712).Conclusion Single heartbeat cardiac imaging has a high accuracy of findings on the degree of coronary artery stenosis,and can directly reflect the internal conditions of t
