摘 要:低剂量螺旋CT(LDCT)是20世纪肺癌筛查的新手段,具有辐射低、无创、快速等特点,且已有临床试验表明,使用LDCT进行肺癌早期筛查可降低高危人群的死亡率。但LDCT筛查带来的假阳性率高、过度诊断等问题也引起了关注与争议。全文就LDCT筛查的现状及前景加以综述。 |

Abstract:Low dose spiral CT seanning is a new approach of screening for lung cancer with advantages of low radiation,non-invasiveness and time-saving.Studies have shown that screening with low dose spiral CT can reduce the mortality of lung cancer in high-risk populations;however,there are still some controversies such as high false positive rate, and issues of overdiagnosis. This article reviews the current status and prospect of low does spiral CT in screening and early detection of lung cancer. |
