Clinically, the dominant radionuclide is 18F, which has a half-life of approximately two hours. It is produced by proton bombardment of a stable oxygen-18 (18O) enriched water target, thanks to nuclear reaction 18O(p,n)18F. Thus, 18O-H

Webexample). This conversion factor is frequently called the system sensitivity. PET Conversion Factor 1) Usually uses tomographic imaging of a uniform cylinder of a given activity density. 2) Image reconstruction requires same attenuation compensation and scatter correction as that used for the patient. SPECT Conversion Factor WebScintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by external detectors (gamma cameras) to form two-dimensional images in a …
