Nuclear medicine maladministrations in New South Wales are uncommon, with approximately 8-9 incidents per 100 000 procedures. Most maladministrations are the consequence of incorrect radiopharmaceutical dispensing. All those which involved diagnostic radiopharmaceuticals resulted in no immediate adverse effects from the radiation exposure.
An 18-year-old woman underwent an (111)In octreotide scan for evaluation of a possible insulinoma. This showed mildly increased radiopharmaceutical uptake involving the right lung base. The patient reported a productive cough for 5 days before the octreotide scan. A chest radiograph was taken, which showed increased airspace opacification in the right lower lobe, corresponding to the uptake seen on the octreotide scan. After a course of oral antibiotics, the patient's chest symptoms improved and the radiograph opacification resolved, confirming the diagnosis of community-acquired pneumonia. This case stresses the need to correlate scan results with the patient's presentation and symptoms to avoid false-positive data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
