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。
We used ELSCINT2400 whole body CT scanner, continuous scan of 205 cases of chest scan, coronary artery calcification found in 44 cases, accounting for 21.5%. Fifty-five cases of coronary artery calcification were not found in patients under 40 years old. Among the 155 patients over 40 years old, the detection rate of coronary calcium increased with age, of which 58 cases were diagnosed as coronary heart disease and 40 cases were coronary artery calcification. Heart disease, 4 cases of coronary calcification. Focus on the relationship between coronary calcium and coronary heart disease, the sensitivity, specificity and positive predictive values were 69%, 96% and 91%. Although CT is not sensitive to detect coronary artery calcification, but it shows a higher probability of coronary heart disease, it should still be considered as an important non-invasive examination.
