Despite its high potential in significant scan time
reduction and its immense popularity, MRI applications
of compressed sensing (CS) have yet to reach daily
clinical usage. With a modest acceleration factor and
with a careful selection of the intended application,
the CS can be fully implemented on todays clinical MR
scanners. The current work successfully demonstrates
this with the Time-of-Flight application (TOFu),
achieving factor of 2 scan time reduction (net
acceleration 3.8) over the conventional intracranial TOF
(acceleration factor of 2 from parallel MRI) without
compromises in image quality.
