BACKGROUND The Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED)
addressed the value of ventilation/perfusion scans in acute pulmonary embolism (PE). The …

To determine the sensitivities and specificities of ventilation/perfusion lung scans for acute
pulmonary embolism, a random sample of 933 of 1493 patients was studied prospectively …

To provide clinical diagnostic criteria for pulmonary embolism (PE), we evaluated 750
consecutive patients with suspected PE who were enrolled in the Prospective Investigative …

To assess the value of perfusion lung scan in the diagnosis of pulmonary embolism, we
prospectively evaluated 890 consecutive patients with suspected pulmonary embolism. Prior …

Pulmonary angiography is the most specific test available for the diagnosis of acute
pulmonary embolism. This technique can safely be performed in critically ill patients. In 367 …

AIM: To determine the validity of a normal pulmonary angiogram in the exclusion of
pulmonary embolism (PE), based on the safety of withholding anticoagulant therapy in …

The purpose of our study was to assess feasibility, safety and clinical utility of selective
pulmonary angiography in patients with suspected pulmonary embolism and a …
