<prompt> All the following test results can exclude pulmonary embolism, EXCEPT:CT pulmonary angiogram: NormalPerfusion scan: NormalD-Dimer Test: PositiveNone of the above  <response>: Test results that confirm or exclude pulmonary embolism adapted from Kearon Diagnostic for pulmonary embolism 85 probability of pulmonary embolism Computed tomography CT pulmonary angiogram: Intraluminal filling defect in a lobar or main pulmonary aery Intraluminal filling defect in a segmental pulmonary aery and moderate or high CPTP clinical pre-test probability. Ventilation-perfusion scan: High probability scan and moderate or high CPTP Positive diagnostic test for deep vein thrombosis with a non-diagnostic ventilation-perfusion scan or CT pulmonary angiogram Excludes pulmonary embolism 2 probability of progressive venous thromboembolism during 3 months follow-up CT pulmonary angiogram: Normal Perfusion scan: Normal D-dimer test: Negative test which has high sensitivity 95 and low or moderate CPTP Negative test which has moderately high sensitivity 85 and low CPTP Non-diagnostic ventilation-perfusion scan or suboptimal CT pulmonary angiogram and normal venous ultrasound of the proximal veins and Low CPTP or Negative D-dimer test which has moderately high sensitivity 85 or Normal repeat venous ultrasound scans of the proximal veins after 7 and 14 days Ref: Kearon C.
