Eur Radiol: How does the size of the nodules found in lung CT screening affect the frequency of screening?

Lung cancer screening (LCS) by low-dose computed tomography ( LDCT) can diagnose lung cancer (LC) early , thereby significantly reducing LC mortality.

Lung cancer screening (LCS) by low-dose computed tomography ( LDCT) can diagnose lung cancer (LC) early , thereby significantly reducing LC mortality.

The effect of annual screening depends on the individual risk assessment of LC.

Recently, a study published in European Radiology reported the distribution of Lung-RADS v1.

Subjects were selected retrospectively in the Multicenter Italian Lung Testing (MILD) trial based on the National Lung Screening Test ( NLST) standards.

Subjects were selected retrospectively in the Multicenter Italian Lung Testing (MILD) trial based on the National Lung Screening Test ( NLST) standards.

Among 1248 subjects who met NLST, the frequency of LC occurrence was 1.

Based on the results of LDCT at baseline, the kaplan-meier curve for the diagnosis of LC within 3 years.

    In summary, this study is the first to use semi-automatic software to segment the nodule volume on thin-layer LDCT to analyze the distribution of Lung-RADS v1.

    The nodule volume obtained by semi-automatic software segmentation can stratify the LC risk of Lung-RADS v1.
