Ultra-high field MRI at 7T holds great potential but also presents significant challenges, often necessitating extensive calibration times to achieve spatially heterogeneous B1+/ΔB0 profiles. This talk explores the development of novel methodologies to address such challenges in cardiac and spinal cord imaging. It includes the creation of calibration-free parallel transmission techniques to eliminate conventional time-consuming calibration routines and covers broadband excitation to compensate for local ΔB0 variations or chemical shifts. Moreover, the presentation delves into respiration-related ΔB0 variations in mid- to lower spinal cord regions, providing essential insights for advancing spinal cord imaging techniques at ultra-high fields.
