Noncontrast-enhanced MRA with investigational version of
IFIR FSE can be obtained for evaluation of arteries from
aortic arch to skull base with compressed sensing (CS)
and parallel imaging ARC within a short period time.
Thirty-seven patients with possible cerebrovascular
diseases were studied. Reduction of imaging time of MRA
with acceptable image quality can be made with ARC 3x2
or ARC 3x1+CS. This technique can be used as a screening
method for neck arteries additional to MRI and MRA of
the head. Further optimization of sequences for ARC and
CS may be required for reduction of imaging time.
