This study proposes the use of a neurovascular coil with
an appropriately optimized T1w-SPACE for vessel wall
imaging of intracranial and extracranial arteries in one
scan. The sequence combined good blood suppression
(through DANTE) and improved T1 contrast (through a
flip-down pulse) to improve image quality. An optimized
refocusing pulses flip angle series for T1w-SPACE and
a good neurovascular coil increased the SNR needed for
high spatial resolution. The method covers a volume of
212mm x 159mm x 40mm with an isotropic spatial
resolution of 0.6mm in 7.5min. The patient study showed
that the method would be clinically relevant.
