This article reviews the evidence on focal incidental uptake including the incidence of malignancy, differential diagnosis and imaging criteria which can be used to further characterize it. The article focusses on PET rather than CT criteria. The strength of the evidence base is highly variable ranging from systematic reviews and meta-analyses to a virtual absence of evidence. Caution needs to be used when using standardized uptake values (SUVs) reported in other studies due to interpatient and institution observed variation in SUVs. There is sufficient evidence to permit specific suggestions on how to interpret the foci and recommend further management in the: pituitary (investigate when SUVmax &amp;gt;4.1), thyroid (investigate all), breast (investigate all), lung parenchyma (if focus of fluorodeoxyglucose without a CT nodule, no further investigations), colon (investigate all foci with SUVmax &amp;gt;5.9, urgently if SUVmax &amp;gt;11.4), adrenals (criteria depend on if patient has cancer) and prostate gland (investigate in males aged &amp;gt;50 years or &amp;gt;40 years if peripheral uptake or patient has other risk factors). There is some evidence to guide further management for the parotid gland, naso-orophaynx, oesophagus, pancreas, uterus and ovaries. There is insufficient evidence to guide management for the liver, spleen, kidneys, gallbladder, testis and bone, for these organs patient characteristics and other guidelines will likely be of more use in determining further management.<\/jats:p>","DOI":"10.1259\/bjr.20170774","type":"journal-article","created":{"date-parts":[[2017,12,15]],"date-time":"2017-12-15T11:35:26Z","timestamp":1513337726000},"source":"Crossref","is-referenced-by-count":35,"title":["Evidence-based
