To extract accurate image-derived input functions from dynamic brain positron emission tomography images (DBPIs) using independent component analysis (ICA). ⋯ We have proposed a technique for estimating image-derived input functions using independent component analysis without blood sampling. The results of our method were highly correlated with those from standard blood sampling, and more accurate than those of other methods proposed previously.

Errors in medicine are being increasingly highlighted. There is potential for harm in nuclear medicine. ⋯ 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.
