FDG-PET/CT is the gold standard for the diagnosis and
the monitoring of large vessel vasculitis, but it causes
repetitive radiation exposure. The presented, novel,
isotropic-high-resolution three-dimensional T1w TSE
sequence (VISTA Volumetric ISotropic TSE Acquisition)
was evaluated in 23 patients with suspected large vessel
vasculitis and 25 controls. The study showed that the
navigated 3D black-blood MRI technique with peripheral
pulse unit triggering is able to diagnose large vessel
vasculitis of the thoracic vessels in 10-12 minutes scan
time. Future studies are necessary to evaluate VISTA-MRI
for monitoring of anti-inflammatory therapies and to
perform a comparison with PET/CT and ultrasound.
