Yield of computed tomography pulmonary angiogram in the emergency department in cancer patients suspected to have pulmonary embolism

ABSTRACT

Objective/background: The use of computed tomography pulmonary angiography [CTPA] in the emergency department [ED] for patients suspected to have pulmonary embolism [PE] has been steadily rising in the last 2 decades. However, there are limited studies that specifically address the use of CTPA in the ED for cancer patients suspected to have PE. The objective of this study is to assess the rate of positive PE by CTPA in the ED in cancer patients and the variables that are associated with positive results:
