High field MRI has introduced new challenges especially for body imaging with respect to B1 field non-uniformities. Parallel RF transmission allows for more homogeneous excitation, thus improving image quality especially for T2-weighted liver imaging at 3.0 Tesla. Therefore, we evaluated 52 patients in an intraindividual study design to determine the effect of parallel RF transmission on lesion detectability for T2-weighted imaging as compared to conventional MR imaging. Our data demonstrate a significantly higher detection rate of focal liver lesions using parallel RF transmission.
