Synopsis

Keywords: High-Field MRI, BrainWe present single channel universal GRAPE pulses for optimized T1 and T2 weighted (fluid suppressed) imaging on clinical ultra-high field systems. B0 and B1 inhomogeneities are effectively mitigated while no pulse calculations are necessary during the imaging session. Compared to a parallel transmission set-up SAR estimation is less complex, and with more established history of safe use, it makes this approach a promising tool for clinical applications such as lesion detection.
