The simultaneous ventilation and perfusion radionuclide scanning is the most

embolus. The aim of this investigation is to reveal areas of ventilation-perfusion
mismatch. Another method to detect blockage of the pulmonary artery or its
branches is the pulmonary angiogram/angiography and especially CT.
