(author), Steinbach, O.C. (author), de Groot, J. (author)Introduction: The efflux transporters P-glycoprotein (P-gp, ABCB1) and breast cancer resistance protein (BCRP, ABCG2) are expressed at the blood-brain barrier (BBB), and can limit the access of a wide range of drugs to the brain. In this study we developed a PET-CT imaging method for non-invasive, quantitative analysis of the effect of ABCB1 and...article 2015

(author), Sterenborg, H.J.C.M. (author)Objectives: To validate near-infrared (NIR)-based optical spectroscopy measurements of hepatic fat content using a minimally invasive needle-like probe with integrated optical fibers, enabling real-time feedback during percutaneous interventions. The results were compared with magnetic resonance spectroscopy (MRS) as validation and with...article 2012

Läppchen, T. (author), Vlaming, M.L.H. (author), Custers, E. (author), Lub, J. (author), Sio, C.F. (author), DeGroot, J. (author), Steinbach, O.C. (author)In recent years, [ 18F]gefitinib PET has successfully been employed for a number of applications ranging from oncology to in vivo studies of drug transporter proteins. We here report a reliable, automated procedure for routine synthesis of this radiotracer on an Eckert and Ziegler modular system. The 3-step radiosynthesis followed by preparative...article 2012
