Vascular imaging is an important step in the assessment
of stroke; however, optimal evaluation of the neck
vasculature often requires multiple sequences. The
purpose of this study was to develop a non-contrast
method of evaluating the carotid arteries from the
aortic arch to skull base with excellent resolution in
acceptable time parameters. Inflow-enhanced inversion
recovery with fast spin echo readout (IFIR-FSE) was
combined with parallel imaging and compressed sensing
and compared to both contrast enhanced MRA and
time-of-flight MRA in volunteer patients. After the
image quality was optimized, patients were recruited to
demonstrate feasibility in the clinical setting.
