CT has emerged as a potentially important diagnostic technique in pulmonary thromboembolism that can provide direct visualization of the obstructing embolus and its associated vascular and pleuroparenchymal sequelae. Although the role of contrast-enhanced CT in the diagnostic algorithm of pulmonary embolism has not been defined, patients at risk for pulmonary embolism frequently undergo thoracic CT as part of the assessment for other cardiopulmonary conditions. As such, CT may provide the first indication of clinically significant pulmonary embolic disease. This essay reviews the vascular, pleural, and parenchymal features of pulmonary thromboembolism observed on CT scans, describes the limitations of CT, and discusses the imaging features of pulmonary embolism that overlap other clinical conditions.
