| ## Dataset description |
|
|
| The NLST investigated whether low-dose CT screening could reduce lung cancer mortality in high-risk individuals. Between 2002–2004, 53,454 participants were randomized to three annual screenings with either low-dose CT or chest radiography. This dataset includes low-dose CT scans from 26,254 subjects and histopathology images from 451 subjects, enabling research on early detection and screening efficacy. |
