Figure 10 (A-D): Iodine map (DECT-CTPA) in an 83-year old female with chronic pulmonary thromboembolism. (A and C) Axial and coronal color-coded iodine map overlay generated from pulmonary arterial phase shows multiple wedge-shaped perfusion defects peripherally in bilateral hemithorax. (B and D) Axial and coronal colour –coded iodine map overlay of subsequently acquired aortic phase; shows uniform distribution of iodine bilaterally suggestive of homogenous arterial perfusion (through systemic collaterals), filling previous areas of pulmonary perfusion defects
