Purpose: This study tests the hypothesis that the absence of deep venous thrombosis (DVT) on lower extremity color-flow venous duplex examination (LECFD) combined with a non-high-probability ventilation/perfusion (V/Q) scanning result rules out pulmonary embolus (PE). The use of LECFD as a diagnostic aid for PE is based on data that show that 90% of PE originate from lower extremity DVT, …

7/17/2004 · I therefore believe that the key factor in the diagnosis of pulmonary embolism is clinical assessment with clinical pretest probability. In patients with high clinical pretest probability and signs and symptoms consistent with a large pulmonary embolus, a chest CT should be the diagnostic imaging technique of choice, with a view to doing venous ultrasonography if the chest CT is non-diagnostic.
