For dynamic contrast-enhanced pulmonary perfusion MRI, spatial resolution is usually compromised for full lung coverage and high temporal resolution making it difficult to detect structural abnormalities (e.g. pulmonary emboli or interstitial lung disease) on the same scan. This work demonstrates a method to simultaneously acquire both perfusion images and co-registered high-resolution structural images using breath-held 3D radial UTE in healthy subjects.
