Lesson 1Integrating clinical context: risk factors, timing, pleuritic pain, oxygenation, biomarkers (D-dimer, troponin) and how they change diagnostic weightingDis part explain how to mix imaging with patient story for acute dyspnea, bringing in risk factors, when symptoms start, pleuritic pain, oxygen levels, and blood tests like D-dimer and troponin to fine-tune we diagnosis chances.
