An Intrapatient Comparison of 18FDG And 68Ga-DOTA-TATE PET/CT Imaging in Patients with Gastrointestinal Neuroendocrine Neoplasm

#1826

Introduction: 18FDG-PET/CT was the most widely used functional imaging for cancer, while 68Ga-DOTA-TATE PET/CT could evaluate the SSTR expression of NEN.

Aim(s): This study aimed to assess the value of 18FDG and 68Ga-DOTA-TATE PET/CT in Gi-NEN patients and illustrate the correlation between glucose metabolism, SSTR expression and differentiation of tumor.

Materials and methods: 36 patients (27 males, 9 females, age: 27-77 years) with definite histological diagnosis of Gi-NEN who underwent 18FDG and 68Ga-DOTA-TATE PET/CT in two weeks were involved in this retrospective study. All the patients had primary lesions or metastases. G/F= (68Ga-SUVmaxlesion/68Ga-SUVmax normal liver) / (18F-SUVmaxlesion/18F-SUVmax normal liver)
