Effect of erlotinib therapy on parent fractions. Comparison of mean (Ā±SD) arterial parent fractions of [11C]erlotinib with and without erlotinib therapy (a). Correlation of V T change and arterial parent fractions change at 60Ā min postĀ injection (b). Arterial blood SUV, i.e., activity normalized to injected dose and patient weight, in patients off and on therapy (c). Abbreviations: V T volume of distribution, SUV standardized uptake value, Eā without erlotinib therapy, E+ with erlotinib therapy
