T2 weighted imaging of the spine is commonly performed using Turbo Spin Echo (TSE) sequences, resulting in long scan times and vulnerability to motion artifacts. While the single-shot sequences such as HASTE could be used for rapid screening, their use is limited by poor spatial resolution and SAR limitations. We investigated the use of a variable flip angle HASTE (HASTE-VFA) sequence for ultrafast motion robust T2 weighted spine imaging and compared its performance to T2 TSE in 13 patients.
