No report has been found to compare the capability for lung cancer screening among pulmonary MR imaging with ultra-short TE (UTE), low-dose CT (LDCT) and standard-dose CT (SDCT). We hypothesized that pulmonary MR imaging with UTE has a similar potential to detect pulmonary nodules and evaluate Lung-RADS classification and can apply lung cancer screening as well as CT. The purpose of this study was to compare the capability for lung cancer screening among pulmonary MR imaging with UTE and both dose CTs.
