Ancient mummified samples have ultra-short T2* which decreases with increasing field strength. Here, image quality and T2* relaxation times are compared for different tissues of a mummified hand between a clinical 3T and a preclinical 9.4T system using a 3D UTE sequence. Although T2* is shorter at 9.4T, image quality was superior to 3T, justifying the benefits of ultra-high fields (UHF).
