We describe the use of sparse data sampling and
constrained iterative reconstruction to provide a
comprehensive contrast-enhanced brain exam. Data
acquisition is performed with a 3D Cartesian radial
trajectory that is amenable to retrospective definition
of the temporal resolution. Multiple image
reconstructions are performed to obtain all salient
pieces of information desired from a contrast enhanced
brain exam. We demonstrate that pre- and post-contrast
anatomical T1-weighted images, dynamic angiography,
quantitative permeability mapping, and quantitative
perfusion mapping can all be achieved simultaneously -
with high spatial resolution and full brain coverage.
