Lesson 1CT features a primary lung malignancy: spiculated nodule, mass, cavitation, central vs peripheral locationReviews hallmark CT appearances a primary lung cancers, includin nodule an mass morphology, margins, cavitation, an location, an explains how dese features relate to histologic subtype, aggressiveness, an potential resectability.
Solid, subsolid, and ground-glass nodulesSpiculation, lobulation, and marginsCavitation and air bronchograms in tumorsCentral versus peripheral tumor patternsEndobronchial and perihilar massesCT clues to histologic subtypeLesson 2Reporting structure: Technique, Findings, Impression, an Recommendations tailored to lung cancerExplains how to structure lung cancer CT reports, detailin technique documentation, organized description a thoracic findings, clear impression statements, an specific, evidence-based management recommendations fi referrers.
Essential CT technique documentationOrganizing lung and mediastinal findingsDescribing nodules, masses, and invasionStandardized language for impressionsActionable recommendations and follow-upCommunicating uncertainty and limitationsLesson 3Staging basics pon CT (TNM elements visible pon CT) an when to recommend PET/CT or biopsyIntroduces CT-based TNM concepts fi lung cancer, detailin visible T, N, an M features, common staging pitfalls, an when CT findings should prompt PET/CT, tissue sampling, or referral to a multidisciplinary tumor board.
CT assessment of primary tumor T stageNodal disease patterns relevant to N stageDetecting distant metastases on CTCommon CT staging pitfalls and trapsIndications for PET/CT after CTWhen to recommend biopsy or bronchoscopyLesson 4Pulmonary metastases vs primary tumor: radiologic distinctionsCompares CT appearances a pulmonary metastases wid primary lung cancers, highlightin distribution, number, morphology, an ancillary findings dat favor one diagnosis over di odda, an discussin di role a clinical context.
Typical patterns of pulmonary metastasesSolitary metastasis versus primary cancerCalcified and hemorrhagic metastasesLymphangitic carcinomatosis featuresRole of known extrathoracic malignancyWhen imaging cannot distinguish originLesson 5Imaging anatomy a lungs, mediastinum, an pleura pon CTProvides a focused review a normal CT anatomy a lungs, mediastinum, an pleura, usin axial, coronal, an sagittal planes to build a mental map dat supports accurate localization an characterization a thoracic abnormalities.
Lobar and segmental lung anatomyHilar and mediastinal compartment layoutMajor airways and bronchial treePulmonary arteries and veins on CTPleural reflections and recessesUsing multiplanar reformats for anatomyLesson 6CT acquisition protocols an contrast phases fi chest imagingDetails chest CT acquisition choices fi lung cancer workup, includin slice thickness, reconstruction kernels, contrast timin, an special protocols such as high-resolution an angiographic studies dat influence lesion detection an characterization.
