• Optimized pulmonary computed tomography angiography (PCTA) for pulmonary embolism detection is a complex undertaking involving selection of contrast volume, injection timing, scanning parameters, and interaction with patient (breath-holding). • Breathing techniques and cardiac gating can optimize CTA image quality by decreasing various respiratory and motion artifacts. • The controversial clinical significance of small subsegmental pulmonary emboli. • The prognostic value of right ventricular function assessment. • The emerging technology of lung perfusion imaging using dual energy computed tomography. • New imaging techniques play an important role in guiding treatment decisions as well as future research investigations.  

• Review how to optimize CTA image quality with the strategic use of intravenous contrast, scanning parameters, breathing techniques, and electrocardiographic gating. • Review the value of different treatment possibilities of small subsegmental pulmonary embolism and recommendations to initiate anticoagulation. • Review approaches to right ventricular function evaluation. • Review the ability of new CT technologies to add new information (lung perfusion), improve spatial resolution, and reduce radiation dosage.
