Clinical Outcomes in Patients With Suspected Acute Pulmonary Embolism and Negative Helical Computed Tomographic Results in Whom Anticoagulation Was Withheld

Abstract

Our data support helical CT as a safe, definitive, minimally invasive test that is associated with a low 3-month risk of venous thromboembolism, and may be comparable to results of negative pulmonary angiography or low-probabililty ventilation-perfusion scan.
