Clinical outcomes after investigation for pulmonary embolism using CT angiography and venography.

Background: The diagnosis of pulmonary embolism (PE) still requires long work-up periods and multiple tests.

Objective: We aim to assess clinical outcomes after a negative investigation using a combined protocol of CT pulmonary angiography and CT venography (CTA/CTV) as a sole diagnostic test in unselected patients with suspected PE.

Methods: This retrospective cohort study enrolled consecutive patients with suspected PE who were investigated with a combined CTA/CTV protocol.
