Fig. 3From: The value of CT shape quantification in predicting pathological classification of lung adenocarcinomaTwo-dimensional schematic diagram and actual tumor measurement diagram of GGN. (a) Two-dimensional schematic diagram, we chose angle A (77.03°) and angle B (60.55°) as the big angle (BiA) and the small angle (SmA), respectively. Then, we obtained the BiA/SmA ratio (77.03°/60.55°), which was approximately 1.2722. (b) Actual tumor measurement imageBack to article page
