In-Depth Guide & Mathematical Methodology
🩺 PE Diagnostic Algorithm per ESC Guidelines
Wells ≤ 4 points (Improbable PE): High-sensitivity D-Dimer test. If negative, PE is ruled out safely. If positive, proceed to CTPA.
Wells > 4 points (Probable PE): Skip D-Dimer. Proceed directly to CT Pulmonary Angiography (CTPA) and initiate empiric anticoagulation if no contraindications.
