The role of radiomics in the detection of lymph node metastases

The authors of this retrospective analysis looked at the role that radiomics played when applied to contrast-enhanced computed tomography (CT) in detecting lymph node (LN) metastases in lung cancer patients compared to 18F-fluorodeoxyglucose positron emission tomography (PET)/CT as a reference. The authors determined that radiomics showed good discrimination power, regardless of the modelling technique, in detecting LN metastases in lung cancer patients.

Key points

• Radiomics applied to contrast-enhanced computed tomography is feasible in detecting lymph node metastases in patients with proven lung cancer.
• The least absolute shrinkage and selection operator (LASSO) classifier is suitable as a diagnostic tool applied to radiomics in this setting.
• Radiomics failed to improve clinical benefit as a prescreening tool.
