Tc-HYNIC-TOC) in thedetection of colorectal neuroendocrine neoplasms.
Methods:
99m
Tc-HYNIC-TOC imaging data of 122 patients with colorectal neuroendocri
ne neoplasms were analyzed retrospectively
including 26 in appendix
90 in rectum
3 in sigmoid colon
2 in transverse colon
1 in descending colon. Whole-body imaging and SPECT/CT imaging were obtained 2 h after intravenous injection of 370- 555 MBq
