AbstractRecent studies have supported the use of low-dose computed tomography (LDCT) of the chest as a screening tool for lung cancer. Several professional organizations have now included LDCT screening in high-risk populations in their guidelines. The United States Preventive Services Task Force has added LDCT to its lung cancer-screening guidelines as of December 2013. Recently, the Centers for Medicare and Medicaid Services acknowledged that the evidence for LDCT lung cancer screening is adequate, provided that eligibility criteria are met. As widespread use of LDCT is anticipated, the radiation dose associated with LDCT needs to be optimized. The American College of Radiology-Society of Thoracic Radiology collaboration and the National Comprehensive Cancer Care Network recently provided some guidelines for LDCT utilization for lung cancer screening. There are several scanning and image reconstruction techniques that can be used for reducing radiation dose in LDCT lung cancer screening. This review article presents protocols and guidelines for use of LDCT in lung cancer screening and describes our early experience in implementing LDCT at our institution.
