First Clinical Experience on Ultra-High Field MRI in Patients with Multiple Sclerosis: Comparison of 1.5 T and 7.0 T

Purpose: The purpose of this study was to investigate the potential of high resolution imaging of MS lesions in vivo comparing 7 T with conventional 1.5 T in detecting white and gray matter lesions. Materials and Methods: Twelve patients with clinically definite relapsing remitting MS (mDD 5 years, mEDSS 2.8) were scanned on a 7 T whole-body scanner (Magnetom 7 T, Siemens) with a 8-channel phased-array, transmit receive head coil (Rapid Biomedical GmbH, Würzburg, Germany) and on a 1.5 T Avanto (Siemens) with a 12-channel phased array head coil. The imaging protocol consisted of high-resolution axial PD + T2-TSE,…
