Lesson 1Integrating clinical context: risk factors, timing, pleuritic pain, oxygenation, biomarkers (D-dimer, troponin) and how they change diagnostic weightingThis bit shows how to mix scan results with patient details for breathing trouble, like risks, when symptoms started, chest pain on breathing, oxygen levels, and blood tests like D-dimer and troponin to narrow down what's wrong.
