  • Title: Gastric visualization and image quality in radionuclide bone scanning: concise communication.
    Author: Wilson MA, Pollack MJ.
    Journal: J Nucl Med; 1981 Jun; 22(6):518-21. PubMed ID: 6453210.
    Abstract:
    In a 12-mo study period, there were 14 days identified when the stomach was visualized in routine bone imaging. On these days, 44% of the 110 patients imaged demonstrated this effect. Only the quality control, binding efficiency, and scan quality differed (p less than 0.005) when the study population was compared with a reference population of 162 patients. However, on the days when this effect was noted, there was a significant (p less than 0.001) linear correlation between the presence and degree of gastric visualization and the radiopharmaceutical incubation and quality control parameters. The study suggests a sporadic phenomenon that appears to result from partial oxidation of the agent during incubation, producing (a) different species of labeled diphosphonate that display altered affinity for bone (scan quality) and (b) free pertechnetate (gastric activity).
