Purpose: The approximately 4.7 times higher signal at 7 T compared with that at 1.5 T may improve image quality of clinical MR-angiograms and should therefore provide a superior visualization of intracranial arteries and aneurysms. The purpose of this study was to determine whether 7 T ToF-MR-angiography is superior to 1.5 T ToF-MR-angiography in the detection and evaluation of intracranial aneurysms. Materials and Methods: 10 patients with suspected or known intracranial aneurysms underwent 7 T ToF-MRA (Magnetom 7 T, Siemens, Erlangen, Germany), 1.5 T ToF-MRA (Magnetom Espree or Sonata; Siemens, Erlangen, Germa…
