Insulinoma on mri sag localizer6/15/2023 Routine MRI sequences were obtained, including axial T1- and T2-weighted images, and axial T1-weighted images with fat saturation before and after intravenous administration of gadolinium. MRI was performed using a 1.5 Tesla scanner (GE Healthcare, Little Chalfont, UK). MDCT imaging was performed using a 64-slice multi-detector CT scanner (GE Healthcare, Milwaukee, WI, USA). In our study, CEUS were performed by doctors with >10 years’ experience. Patients were excluded if they had other severe diseases, such as kidney, heart, or liver failure, if they were allergic to contrast agents, or if they were pregnant. The inclusion criteria were age >18 years, insulinoma, no allergy to contrast agents, and biochemically proven endogenous hyperinsulinemic hypoglycemia. All study participants provided written informed consent prior to therapy. The present study was approved by the Ethics Committee of Chinese PLA General Hospital. Other causes of hypoglycemia were excluded. Symptomatic hypoglycemia with elevated plasma insulin and C-peptide levels were confirmed by prolonged supervised fasting and/or glucose tolerance test. Clinical histories and relevant biochemical results were obtained from chart reviews. Insulinomas were confirmed by glucose tolerance test and imaging data. This was a retrospective study including patients with insulinomas identified at a single center (Chinese PLA General Hospital) between November 2013 and October 2014.
