Can a penalized-likelihood estimation algorithm be used to reduce the injected dose or the acquisition time in (68)Ga-DOTATATE PET/CT studies?
BACKGROUND: Image quality and quantitative accuracy of positron emission tomography (PET) depend on several factors such as uptake time, scanner characteristics and image reconstruction methods. Ordered subset expectation maximization (OSEM) is considered the gold standard for image reconstruction....
