The cover image shows peptide-targeted SPECT/CT imaging of gliomas. Radiolabeled (indium, ¹¹¹In) CooP peptide was injected into the tail vein of intracranial U87MG tumor-bearing mice. Two hours after injection, accumulation of the ¹¹¹In-conjugated CooP peptide was detectable using the SPECT/CT whole-body imaging device in brain tumors (mouse on left), while no control peptide could be detected in the tumors (mouse on right). For details, see article by Hyvönen et al., on page 996.
