Entropy Proposed as a Third Pillar for Lung Nodule Risk Assessment

A new study in AJR proposes using entropy—a measure of tissue heterogeneity—as a third pillar alongside size and morphology for lung nodule risk stratification. (Exact findings not reported in source.)

• Entropy quantifies internal heterogeneity of nodules and may complement traditional size and morphology assessment.
• The study design, sample size, and primary results are not available from the provided source.
• Full validation status and clinical impact remain unknown based on the abstract alone.
