Lesson 1CT features of primary lung malignancy: spiculated nodule, mass, cavitation, central vs peripheral locationReviews hallmark CT appearances of primary lung cancers, including nodule and mass morphology, margins, cavitation, and location, and explains how these features relate to histologic subtype, aggressiveness, and potential resectability.

Typical patterns of pulmonary metastasesSolitary metastasis versus primary cancerCalcified and hemorrhagic metastasesLymphangitic carcinomatosis featuresRole of known extrathoracic malignancyWhen imaging cannot distinguish originLesson 5Imaging anatomy of lungs, mediastinum, and pleura on CTProvides a focused review of normal CT anatomy of lungs, mediastinum, and pleura, using axial, coronal, and sagittal planes to build a mental map that supports accurate localisation and characterisation of thoracic abnormalities.
