Use of18F-DOPA PET/MRI for the Detection and Localization of Focal Forms of Hyperinsulinism
Washington University School of Medicine
Summary
The purpose of the study is to provide access to 18F-DOPA PET to patients at Washington University and assess the utility of 18F-DOPA PET/MRI as a preoperative tool to detect and localize focal lesions in the pancreas that are causing hyperinsulinism.
Description
Congenital hyperinsulinism (CHI) is a clinically and genetically heterogeneous disorder that is the most common cause of permanent hypoglycemia in infants and children. More than 50% of the medically-unresponsive patients have focal disease. Which is characterized by a distinct region of Beta-cell hyperplasia in the pancreas, due to a somatic loss of a gene that regulates cell proliferation. Resection of the involved region cures most cases of focal HI. Therefore, preoperative identification and localization of focal HI lesions is useful for diagnostic confirmation and surgical guidance of pat…

Inclusion Criteria: 1. Patients with confirmed hyperinsulinemic hypoglycemia, diagnosed by elevated insulin levels during hypoglycemia and/or response to glucagon stimulation. 2. Subjects who failed pharmacological therapy with diazoxide or octreotide. 3. Subjects with signed informed consent by themselves or their parents or legal guardians. 4. Patient's Endocrinologist has determined that the patient cannot be safely managed with standard medical therapy (failed) and surgery is recommended to prevent future episodes of severe hypoglycemia and preserve brain function.

Interventions
- Drug18F-Fluoro Dopa PET/MRI Imaging
The purpose of this research study is to provide access to an imaging study of the pancreas that uses 6-\[18F\]-Fluoro-L-3,4,-dihydroxyphenylalanine (18F-DOPA)positron emission tomography (PET) and assess the accuracy of this 18F-DOPA-PET/MRI test on distinguishing what part of the pancreas is affected in patients with Hyperinsulinism.
