摘　　要：目的:探讨在胸部健康体检中,对可疑病变进行数字化断层融合(digital tomosynthesis,DTS)检查的意义。方法:搜集健康体检者1 000例分为2组,其中青年组500例,老年组500例。1 000例健康体检者均先行胸部数字化X线摄影检查(digital radiography,DR),对可疑病变进行DTS检查,分析肺阳性病变的检出率。结果:1 000例体检者当中,胸部DR发现可疑病变110例,其中青年组8例,老年组102例;对可疑病变进行DTS检查,发现结节92例,其中青年组4例,老年组88例;对92例肺结节患者行CT检查,癌性结节为89例。结论:在健康体检当中,对可疑病变及时进行DTS检查,能够及时发现病变,为患者的早期诊断与治疗提供重要依据。Objective To investigate the significance of digital tomosynthesis（DTS）for suspicions lesions in the physical examination of the chest.Methods Totally 1 000 physical examinees were divided into two groups,with 500 younger ones in one group and the remained 500 ones in the other.The examinees underwent examination with digital X-ray radiography,and then the suspicious cases went through DTS examination to analyze the detection rate of pulmonary positive results.Results There were 110 suspected cases found by digital X-ray radiography,including 8 young ones and 102 old ones.The suspected cases went through DTS examination,and totally 92 nodules were found including 4 ones in the young persons and88 ones in old persons.CT examination found 89 carcinomatous nodules in the 92 ones.Conclusion DTS examination can detect the lesion of the physical examinee,and lays a foundation for early diagnosis and treatment.
