CT pulmonary angiography has become the standard of care for assessment of patients with pulmonary embolism (PE). There are many exciting new applications of Dual-energy CT (DECT) for advanced imaging of PE. The capability of the DECT to use diagnostic information from both 80 and 140 kVp datasets optimizes the contrast-to-noise ratio within vessels and facilitates detection of peripheral endoluminal clots. Low-kV dataset increases vascular enhancement. A number of predictive markers are established for risk stratification and to evaluate the prognosis in acute and chronic PE. DECT is capable of iodine mapping of the pulmonary parenchyma, to show segmental defects in iodine distribution in areas corresponding to embolic vessel occlusions. Diagnostic scans and lung perfusion scans are routinely reconstructed and several available image reconstruction techniques are available for DECT imaging to enhance detection and management of PE.

1. Basic principles of spectral CT and available techniques of DE data acquisition. 2. Image processing and reconstruction of DECT data. 3. Clinical application of DECT for diagnosis and management PE. 4. Sample cases 5. Advantages of DECT imaging over other imaging modalities for diagnosis of PE. 6. Limitations of DECT imaging such as the effects on image quality and radiation dose.
