"A ventilation/perfusion (V/Q) scan will show ventilation-perfusion mismatches. A high probability scan is defined as showing two or more unmatched segmental perfusion defects according to the PIOPED criteria."
"RVD:LVD (largest right ventricular transverse diameter to largest left ventricular transverse diameter) ratio >1 on standard axial or reconstructed four-chamber views 38; however, most accurate if measured from true short axis at plane of tricuspid (for RV) and mitral (for LV) valves"

"CT pulmonary angiography (CTPA) will show filling defects within the pulmonary vasculature with acute pulmonary emboli. When the artery is viewed en face (perpendicular to its length), the central filling defect (i.e., the thrombus) is surrounded by a thin rim of contrast, called the polo-mint sign."

"D-dimer (ELISA) is commonly used as a screening test in patients with a low- and moderate-probability clinical assessment; in these patients:"
"Westermark sign: regional oligaemia (10%); has the highest positive predictive value"
"Emboli may be occlusive or non-occlusive; the latter is seen with a thin stream of contrast adjacent to the embolus. Typically, the embolus forms an acute angle with the vessel, unlike chronic emboli. The affected vessel may also enlarge 9."

"While classical signs in isolation have limited value, multi-organ point-of-care ultrasonography combining cardiac, lung and venous ultrasound has a sensitivity >95% 42,43. In haemodynamic compromise, ultrasound is particularly useful as a triaging tool. Echocardiography may be of value to assess for the presence of severe right ventricular dysfunction 14:"
"Providing cardiopulmonary support is the initial treatment. Anticoagulation is provided in patients without a risk of active bleeding. Thrombolysis is an option with large emboli or a large clot burden. In some cases, embolectomy or placement of a vena cava filter is required."
