Detection rate for abdominopelvic lymph nodes by size on 3- and 8-min PET acquisitions (a). The 8-min PET is more sensitive for lymph nodes smaller than 1 cm (p < 0.001). The 3- and 8-min PET detected all lymph nodes larger than 1 cm. Example, 0.7-cm right external iliac lymph node visible on T2-weighted images (b), fused PET/MR images (c), and on 8-min PET acquisition (d), but not seen on 3-min PET acquisition (e). The right ureter is designated with a black arrow
