1. To describe the CT findings of chronic thromboembolic disease at Dual CT angiography 2. To provide a differential diagnosis of pulmonary embolism and focal iodine defects in perfusion maps of dual CT 3. To explain that Dual-energy CT offers a “one-stop” assessment of anatomy and perfusion in CTEPH  

1. Introduction 2. Dual energy CT pulmonary angiography technique 3. CT angiography features    a. Direct signs    b. Indirect signs       i. Related to pulmonary hypertension       ii. Related to systemic collateral supply 4. Dual-Energy CT imaging    a. Parenchymal findings    b. Virtual non contrast findings       i. Calcifications       ii. Tumoral uptake    c. Iodine maps of dual CT 5. Other imaging techniques    a. Digital Angiography. Correlation with dual source pulmonary angiography    b. Pulmonary scintigraphy. Correlation with iodine maps 6. Differential Diagnosis    a. CT angiography       i. Acute embolism       ii. Proximal interruption of the pulmonary artery       iii. Non thrombotic embolism       iv. Arteritis       v.
