“…As displayed in Table 2, several studies have reported high TIO detection rates with 68 Ga-DOTA-TATE PET/CT, ranging from 83% to 100% (6,7,15,20,(23)(24)(25)(26)(27). Zhang et al (8) and Yu et al (22) reported similar high sensitivity, specificity, and accuracy in the detection of TIO. In contrast, several studies demonstrated a similar high diagnostic accuracy of 68 Ga-DOTA-NOC and 68 Ga-DOTA-TOC for the localization of TIO (4,5,11,28,29).…”
