The purpose of this study was to compare the visualization of microbleeds with T2*-weighted imaging on 1.5T with dual echo T2*-weighted imaging at 7T and assess the reliability of the detection of microbleeds with the two field strengths. 3D dual echo T2*-weighted imaging at 7T results in detection of microbleeds in more patients, detection of a higher number of microbleeds better and more reliable detection of microbleeds compared to 3D T2*-weighted imaging at 1.5T.
