A 75-years old male with suspicion of insulinoma—^99mTc-GLP1scintigraphy.

<p>^99mTc-GLP1scintigraphy revealed the focus of insulinoma in the pancreas—patient was disqualified from surgical excision of the tumor due to severe heart failure. The study was performed with dual-head, large field of view E.CAM gamma camera with low-energy high resolution (LEHR) collimators and images were evaluated with CT examination imposed by software fusion. A. Fusion of GLP-1 receptor imaging and CT—axial slice, B. CT—axial slice.</p

A 77-year old female—^99mTc-GLP1-SPECT/CT.

<p>^99mTc-GLP1-SPECT/CT (Single Photo Emission Computed Tomography/Computed Tomography) revealed bifocal insulinoma (one focus is well visible on the border of the pancreatic body and tail, T/nT (Target/non-target) ratio 3.4; the second one is smaller, less visible in the pancreatic tail, T/nT ratio 1.7). Lesions were not detected by other diagnostic methods. Histopathology confirmed two foci of insulinoma: 9 mm and 2 mm in diameter. A. GLP-1 receptor imaging—MIP (<i>Maximum Intensity Projection</i>), B. Fusion of GLP-1 receptor imaging and CT—axial slice, C. CT—axial slice.</p
