Dose determination using alanine detectors in a mixed neutron and gamma field for boron neutron capture therapy of liver malignancies

2011

IntroductionBoron Neutron Capture Therapy for liver malignancies is being investigated at the University of Mainz. One important aim is the set-up of a reliable dosimetry system. Alanine dosimeters have previously been applied for dosimetry of mixed radiation fields in antiproton therapy, and may be suitable for measurements in mixed neutron and gamma fields.Materials and MethodsTwo experiments have been carried out in the thermal column of the TRIGA Mark II reactor at the University of Mainz. Alanine dosimeters have been irradiated in a phantom and in liver tissue.ResultsFor the interpretation and prediction of the dose for each pellet, beside the results of the measurements, calculations …

On the applicability of [18F]FBPA to predict L-BPA concentration after amino acid preloading in HuH-7 liver tumor model and the implication for liver…

Abstract Introduction In recent years extra-corporal application of boron neutron capture therapy (BNCT) was evaluated for liver primary tumors or liver metastases. A prerequisite for such a high-risk procedure is proof of preferential delivery and high uptake of a 10 B-pharmaceutical in liver malignancies. In this work we evaluated in a preclinical tumor model if [ 18 F]FBPA tissue distribution measured with PET is able to predict the tissue distribution of [ 10 B]L-BPA. Methods Tumor bearing mice (hepatocellular carcinoma cell line, HuH-7) were either subject of a [ 18 F]FBPA-PET scan with subsequent measurement of radioactivity content in extracted organs using a gamma counter or injecte…
