abstract = {To prospectively evaluate non-contrast-enhanced 7-Tesla (T)
MRA for delineation of unruptured intracranial aneurysms
(UIAs) in comparison with DSA.Forty patients with single or
multiple UIAs were enrolled in this IRB-approved trial.
Sequences acquired at 7 T were TOF MRA and
non-contrast-enhanced MPRAGE. All patients additionally
underwent 3D rotational DSA. Two neuroradiologists
individually analysed the following aneurysm and image
features on a five-point scale in 2D and 3D image
reconstructions: delineation of parent vessel, dome and
neck; overall image quality; presence of artefacts.
Interobserver accordance was assessed by the kappa
coefficient.A total of 64 UIAs were detected in DSA and in
all 2D and 3D MRA image reconstructions. Ratings showed
comparable results for DSA and 7-T MRA when considering all
image reconstructions. Highest ratings for individual image
reconstructions were given for 2D MPRAGE and 3D TOF MRA.
Interobserver accordance was almost perfect for the majority
of ratings.This study demonstrates excellent delineation of
UIAs using 7-T MRA within a clinical setting comparable to
the gold standard, DSA. The combination of 7-T non-enhanced
MPRAGE and TOF MRA for assessment of untreated UIAs is a
promising clinical application of ultra-high-field MRA.•
Non-enhanced 7-T MRA allowed excellent delineation of
unruptured intracranial aneurysms (UIAs). • Image quality
at 7-T was comparable with DSA considering both sequences.
• Assessment of UIAs is a promising clinical application
of ultra-high-field MRA.},
