The resolution of images increases when the magnetic field of the MRI increases: 1 mm resolution at 1.5 tesla, 0.5 mm at 3 tesla, 0.2 mm at 7 tesla. However, as the intensity increases, inhomogeneity of the zones becomes greater and results in a loss of visibility in certain areas. Thus, conventional 7-Tesla birdcage MRIs antennas applied to the head experience a loss of contrast characterized by “the appearance of inhomogeneous areas in three anatomical regions of the brain: the cortex and both temporal lobes,” Redha Abdeddaim, research lecturer at the Fresnel Institute of the University of Aix-Marseille told Bioworld MedTech. Redha Abdeddaim is one of the co-inventors of this new technology for the ultra-high field MRI antenna.
