In Vitro	Depreotide, complexed with technetium-99m to form (99m)Tc-depreotide, binds somatostatin receptors (SSTRs) with high affinity to SSTRs 2, 3, and 5[1].
In Vivo	99mTc-depreotide (sodium chloride 0.9% w/v solution; i.v.; single dose) shows a optimal image interpretation with SPECT images (Single Photon Emission Computed Tomography) between 2 and 4 hours following injection[2].
