Recent developments on high-performance gradients allow MR signals to be encoded much faster than with clinical gradients, hence decreasing T2-related k-space apodization. As a consequence, the point spread function becomes taller and narrower, thus leading to improved actual resolution and higher signal intensity for components with rapid transverse relaxation. In the present work, these benefits are investigated with PSF calculations and demonstrated experimentally using a high-performance gradient. Data of short-T2 tissues (T2 < 1 ms) are acquired using the PETRA technique with different gradient strengths and compared using image subtraction.
