Neuroinformatics
. 2025 Jan;
23(2):11.
PMID: 39841291
Blood flow velocity in the cerebral perforating arteries can be quantified in a two-dimensional plane with phase contrast magnetic imaging (2D PC-MRI). The velocity pulsatility index (PI) can inform on...

Radiologe
. 2019 Jun;
59(10):898-905.
PMID: 31172246
Background: It can be expected that the number of 7 T MRI systems for clinical use will increase in the future. On the other hand, almost no medical implant has...

Magn Reson Med
. 2017 Dec;
80(1):239-247.
PMID: 29194732
Purpose: A prerequisite for cardiac MR (CMR) imaging is adequate synchronization of image acquisition with the cardiac cycle. Electrocardiogram triggering may be hampered by electromagnetic interferences at high field strength....

Neuroimage Clin
. 2014 Nov;
6:93-9.
PMID: 25379420
Background: In Friedreich's ataxia (FA) the genetically decreased expression of the mitochondrial protein frataxin leads to disturbance of the mitochondrial iron metabolism. Within the cerebellum the dentate nuclei (DN) are...
