Reston, Virginia The imaging time window of 64Cu-DOTATATE positron emission tomography/computed tomography (PET/CT) for patients with neuroendocrine neoplasms can be expanded from one hour to three hours post-injection, according to new research published in the January issue of the
Journal of Nuclear Medicine. In a head-to-head comparison of scans performed at the two time intervals, there were no significant differences in the number of lesions detected, and tumor-to-normal tissue ratios remained high in all key organs.
