| Abstract: | Computed tomographic (CT) pulmonary angiography (CTPA) has become the de facto clinical gold-standard for the diagnosis of pulmonary embolism (PE) due to its high sensitivity and specificity. Direct detection or exclusion of PE and diagnosis of various other diseases that mimic symptoms of PE can be accomplished in a single exam. In addition, CTPA allows rapid risk assessment by providing a number of predictive markers for accurate risk stratification and patient management. This article reviews the current role of routine CT techniques and recently introduced dual-energy CTPA for the diagnosis of PE as well as the role of CT for the assessment of right ventricular dysfunction in the setting of acute PE. |
