Cardiac inflammation/infection imaging with 18F-FDG has been very useful in guiding patient management in conditions such as cardiac sarcoidosis, myocarditis, device infections, and prosthetic implant-related infections. Various protocols have been described to suppress normal myocardial glucose uptake. Certainly, there is need for standardization of protocols but adaptation of protocol to suit individual patient needs is also equally important. In the current article in this issue, Alexandra Clément et al have shown that a 7-day ketogenic diet can be used as an alternative method in mice models. This may work well in humans who are unable to fast.
