Tumor Scan with Pentetreotide


File: Tumor_Scan_with_Pentetreotide.pdf

Indium-111 pentetreotide is a [IN-111 DTPA-D-Phe] conjugate of octreotide, a somatostatin analog that binds to somatostatin receptors. This octapeptide concentrates in neuroendocrine and some non-neuroendocrine tumors containing somatostatin receptors.
