Dual Energy CT allows the generation of iodine perfusion maps. This is however not perfusion imaging in the classical sense but rather a static display of iodine based contrast agent in the lung parenchyma. Correlation of static dual energy CT (DECT) derived iodine maps with parameter maps derived from time resolved quantitative pulmonary perfusion MRI showed a high visual, although not statistically significant, correlation between the two modalities.
