Physiological expression of pancreatic somatostatin receptors in 99mTc-HYNIC-TOC scintigraphy.

Purpose: To describe the frequency of head and/or pancreas uncinate process uptake of 99mTc-HYNIC-TOC, to study its nature, and analyze its diagnostic value.

Materials And Methods: Retrospective evaluation of 47 consecutive 99mTc-HYNIC-TOC examinations was conducted. Head and/or pancreas uncinate process uptake was considered to be physiological in patients with normal CT at the same episode and in follow-up.
