In recent preclinical studies, Wong, Mahakian, Rygh and colleagues provided useful comparisons of 64Cu-labelled liposomes, 64Cu-labelled albumin and [18F]FDG, showing that the liposomes were superior to [18F]FDG in detecting small tumours and revealing heterogeneities within tumours, especially when imaging after 18-24 h [[67], [68], [69]]. Here, ALB is linked to neoplasm.
