Pulmonary ventilation imaging in asthma and cystic fibrosis using oxygen‐enhanced 3D radial ultrashort echo time MRI
A previous study demonstrated the feasibility of using 3D radial ultrashort echo time (UTE) oxygen‐enhanced MRI (UTE OE‐MRI) for functional imaging of healthy human lungs. The repeatability ofExpand

Utility of Percentage Signal Recovery and Baseline Signal in DSC-MRI Optimized for Relative CBV Measurement for Differentiating Glioblastoma, Lymphoma, Metastasis, and Meningioma
BACKGROUND AND PURPOSE: The percentage signal recovery in non-leakage-corrected (no preload, high flip angle, intermediate TE) DSC-MR imaging is known to differ significantly for glioblastoma,Expand

Three‐dimensional pulmonary perfusion MRI with radial ultrashort echo time and spatial–temporal constrained reconstruction
We assess the feasibility of spatial–temporal constrained reconstruction for accelerated regional lung perfusion using highly undersampled dynamic contrast‐enhanced (DCE) three‐dimensional (3D) radial MRI with ultrashort echo time (UTE). Expand
