Single-photon emission computed tomography in neurotherapeutics [PDF]

open access: yesNeuroRX, 2005
The measurement of regional cerebral blood flow (rCBF) by single-photon emission computed tomography (SPECT) is a powerful clinical and research tool. There are several clinical applications now documented, a substantial number under active investigation, and a larger number yet to be studied.

111 In-pentetreotide SPECT CT Value in Follow-up of Patients with Neuro-Endocrine Tumors

open access: yesOman Medical Journal, 2014
Carcinoid tumors are relatively rare and can occur in the thorax, abdomen, or pelvis. Functional imaging in the form of Indium-111 pentetreotide scanning is widely used for identification of these tumors and it exploits the fact that the vast majority of

Ga/Lu-labeled DOTA-TATE shows similar imaging and biodistribution in neuroendocrine tumor model

open access: yesTumor Biology, 2017
Somatostatin receptors are overexpressed in neuroendocrine tumors, whose endogenous ligands are somatostatin. DOTA-TATE is an analogue of somatostatin, which shows high binding affinity to somatostatin receptors.
