Quantification of perfusion parameter from dynamic CE-perfusion MRI at 3T system may be more difficult than that at 1.5T system, and contrast media concentration may have larger influence to measurement error of perfusion parameter on a 3T system. We hypothesized that a bolus injection protocol with appropriately small contrast media volume can provide accurate pulmonary perfusion parameter on dynamic CE-perfusion MRI at a 3T system. The purpose of this study was to determine the appropriate contrast media volume for quantitative assessment of dynamic CE-pulmonary MRI, when compared with dynamic CE-area-detector CT (ADCT) for quantitative evaluation of perfusion within whole lung.
