Fig. 3From: Dosimetry methods and clinical applications in peptide receptor radionuclide therapy for neuroendocrine tumours: a literature reviewExample of time-activity curve fitting. Optimal curve fitting using all five time points is represented by the solid black line. The dash-dot line demonstrates what happens if an early time point is not performed; the maximum activity is underestimated. An overestimation of activity in the tail of the curve could occur when a late time point is omitted (dotted line). Adapted from [37]Back to article page
