Comparison of 7  T and 3 T vessel wall MRI for the evaluation of intracranial aneurysm wall

Conclusions7  T provides better visualization of intracranial aneurysm wall with higher sharpness than 3 T. 3 T overestimates the wall thickness relative to 7 T. Aneurysm wall thickness is positively correlated with aneurysm size. 7 T MRI is a promising tool to evaluate aneurysm wall in vivo.Key Points•7  T provides better visualization of intracranial aneurysm wall with higher sharpness than 3 T.•3  T overestimates the wall thickness comparing with 7 T.•Aneurysm wall thickness is positively correlated with aneurysm size.
