Options:
- CT pulmonary angiography (CTPA)
- Ventilation–perfusion (V/Q) scan
- Compression venous Doppler ultrasound of the legs
- Conventional catheter pulmonary angiography
Correct answer: CT pulmonary angiography (CTPA)
Explanation: CT pulmonary angiography (CTPA) is the first‑line test in hemodynamically stable patients because it provides high sensitivity and specificity for PE. CTPA requires IV contrast and cross‑sectional CT acquisition.
