Radiotracer uptake
Tīmeklisin striatal radiotracer accumulation (Laruelle et al. 1997a). In rodent experiments similar changes in the in vivo bind-ing of [3H]raclopride and other low affinity radiotracers to the striatal regions as a result of pharmacologically-in-duced increases or decreases in the levels of extracellular dopamine have been observed (Ross and Jackson 1989a; Tīmeklis2024. gada 8. apr. · Within the framework of the ex vivo studies Trencsényi and colleagues experienced apparently elevated (p ≤ 0.01) radiotracer uptake and T/M ratios in case of the BxPC-3 tumors compared to the other organs. This phenomenon reflects the outstanding PGE2 binding potential of [68 Ga]Ga-NODAGA-RAMEB.

Cells loss from the substantia nigra in PD results in dopamine expending in the striatum, with putamen being affected [ 69 , 70 ].
A radioactive tracer, radiotracer, or radioactive label is a chemical compound in which one or more atoms have been replaced by a radionuclide so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products. Radiolabeling or radiotracing is thus the radioactive form of isotopic labeling. In biological contexts, use of radioisotope tracers are sometimes called radioisotope fe… Tīmeklis2016. gada 1. sept. · We anecdotally observed an increased accumulation of 99mTc-tetrofosmin in the stomach of myocardial perfusion patients when their uptake phase coincided with preparation of hamburgers in an adjacent room for gastric emptying studies on other patients.
