T2-weighted (T2W) iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) V fast spin echo (FSE) imaging can provide good uniformity of fat suppression, but the clinical efficiency is not evaluated. The purpose of this work was to evaluate the clinical efficiency of T2W IDEAL FSE imaging of the cervical spine, compared with conventional fat-saturated T2W FSE, including quantitative measurements of SNR and SNR efficiency and qualitative scoring of diagnostic image quality and fat suppression.
