| 摘 要： | 我们使用ＥＬＳＣＩＮＴ２４００型全身ＣＴ扫描机，连续对２０５例胸部进行平扫检查，发现冠脉钙化４４例，占２１．５％。５０例４０岁以下者未发现冠脉钙化；１５５例４０岁以上者，冠脉钙化检出率随着年龄增加而增加，其中５８例诊断冠心病，４０例有冠脉钙化；９７例无冠心病者，４例有冠脉钙化。着重探讨冠脉钙化与冠心病的关系，其灵敏度、特异度及阳性予告值分别为６９％、９６％及９１％。ＣＴ检出冠脉钙化虽不很敏感，但却能说明发生冠心病的机率较高，因而仍应将它视为一种重要的非损伤性检查方法。

| Abstract: | CT scans without contrast enhancement of the chest in 205 consecutive cases were re-viewed and 44 cases(21.5%)of coronary artery calcification(CAG)were found.There were not CAC in 50 patients under 40 years old.The detection of CAC increased with aged over 40 years old. There were 40 cases of CAC in 58 patients with coronary arteriosclerotic heart disease(CAHD)and there were 4 cases of CAC in 97 patients without heart disease. We studied the relation between CAC and CAHD. The result shown that CAC has positive linear correlation to CAHD. Its sensitivity,specificity and positive prodictive value was 69%,96%and 91% respectively. CAC was not a very sensitive but high specificity suggested that high proba-bility of CAHD. CT is one of the important nontraumtic methods to detect CAC. |
