Lesson 1Integrating clinical context: risk factors, timing, pleuritic pain, oxygenation, biomarkers (D-dimer, troponin) and how they change diagnostic weightingHere we show how to mix scan pictures with patient details like risks, when symptoms started, chest pain on breathing, oxygen levels, and blood tests like D-dimer and troponin to make better guesses on what's wrong.
