An Intrapatient Comparison of 99mTc-HYNIC-TOC with 68Ga-DOTA-TATE for Imaging Abilities of Gastroenteropancreatic Neuroendocrine Neoplasms

#1051

Introduction: Imaging with 68Ga-labled somatostatin analogs provides some advantages over SRS imaging, and has therefore recently become more poprlar.

Aim(s): The aim of this study was to compare the imaging abilities of the recently developed somatostatin analog, 99mTc-HYNIC-TOC with 68Ga-DOTA-TATE in gastroenteropancreatic neuroendocrine neoplasm patients

Materials and methods: Approved by the Beijing cancer hospital ethics committee, thirty-four GEP-NEN patients(17 men, 17 women; age range, 23–75 y; middle age, 51 y) with histologically proven were enrolled in the study. The time interval between the studies using each tracer was less than two weeks.
