Update on gastrointestinal radiopharmaceuticals and dosimetry estimates

Semin Nucl Med. 2012 Mar;42(2):138-44. doi: 10.1053/j.semnuclmed.2011.11.001.


The gold standard technique for measuring gastric emptying is scintigraphy using radiolabeled test meals. Recently, a standardized radiolabeled solid meal has been proposed and adopted by many centers. There is still a need for alternative meals, and several such meals with demonstrated radiolabel stability have been evaluated in small numbers of subjects. Updated radiation dosimetry associated with these meals has been calculated for adult males and adult females with normal gastrointestinal transit as well as transit abnormalities.
