摘　　要：目的:探讨低剂量螺旋CT对胸部健康体检的价值。方法:采用低剂量螺旋CT对1 953例参加健康体检者行胸部扫描,观察肺部、心血管、胸壁(软组织、骨骼)及上腹部的病变。结果:1953例被检者,304例检出肺内非钙化结节,其中21例诊断为肺癌,早期肺癌20例(95%);全部被检者冠状动脉钙化阳性者275例,阳性率为14.1%;胸主动脉钙化阳性者371例,阳性率为19.0%;胸椎骨质增生56例,胸椎压缩骨折8例;乳腺癌1例;脂肪肝23例,肝囊肿10例。结论:采用低剂量螺旋CT胸部体检,不仅可以检出早期肺癌,还可以检出冠状动脉和主动脉钙化斑块、胸壁病变及上腹部病变。一次胸部CT筛查可以检出多脏器具有临床价值的疾病。Objective： To evaluate the thorax screening examined by low-dose spiral computed tomography. Methods： One thou- sand nine hundred and fifty-three individuals underwent thorax scanning with low-dose spiral computed tomography. I.esions of lung, vessels, chest walt（soft tissue and bone）, upper abdomen were studied. Results： Among 1953 cases, 304 cases were found with noncalcified pulmonary nodules （NCN）, 21 cases（6.9% ） had a nodule-associated malignancy, 20 cases（95%） were found to be early-stage lung cancers;275 cases were detected with coronary artery calcification, positive rate was 14.1%; 371 cases with aortic calcification, positive rate was 19.0%. We also found 56 cases with hyperostosis of thoracic vertebrae, 8 ca ses with compression fracture of thoracic vertebrae, 1 case with breast cancer, 23 cases with fatty liver, 10 cases with hepatic cyst. Conclusion： Low dose spiral computed tomography can not only detect early-stage lung cancers, but also find coronary artery calcification, aortic calcification, and diseases of chest wall, upper abdomen. One thorax CT examination has the potentiality to be used as a comprehensive screening tool for many organ diseases with clinical significance.
