目的 :观察冠状动脉钙化 (CAC)的 CT表现及临床意义。方法 :对 2 0 8例胸部 CT图像及临床资料作分析。结果 :2 0 8例胸部CT图像中发现 CAC 63例 (30 .3% )。 40岁以上者 ,CAC检出率随年龄的增加而增加 ,不同年龄组 CAC率差异有显著性 (P<0 .0 1 )。 56例诊断冠心病者 ,41例有 CAC (73.2 % ) ;1 0 2例无冠心病者 ,2 2例有 CAC(2 1 .6% ) (P<0 .0 1 )。结论 :CT能及早发现 CAC,这对冠心病的诊治提供了有力的依据。
Objective: To observe the CT findings and clinical significance of coronary artery calcification (CAC). Methods: Twenty-eight cases of chest CT images and clinical data were analyzed. Results: There were 63 cases (30.3%) of CACs found in 208 cases of chest CT images. The detection rate of CAC increased with the increase of age over 40 years old, there was significant difference in CAC rate among different age groups (P <0.01). Fifty-six patients with coronary heart disease were diagnosed as having CAC (73.2%) in 41 patients; 102 patients without coronary heart disease and 22 patients with CAC (21.6%) (P <0.01). Conclusion: CT can detect CAC early, which provides a strong basis for the diagnosis and treatment of coronary heart disease.
