PURPOSE Recurrent stenosis or occlusion by intimal hyperplasia occurs in up to 40% of patients with tantalum stent implantations in femoropopliteal arteries and greatly restricts their usefulness. We evaluated the effect of prophylactic endovascular radiotherapy on stenosed/occluded stents. METHODS We investigated prophylactic endovascular radiotherapy(More)
PURPOSE Percutaneous transluminal angioplasty (PTA) with or without stent implantation is the accepted standard in the therapy of occlusive arterial disease. Despite improvements in the technique and medical equipment, there is still a restenosis rate of up to 40%. A high-dose-rate afterloading technique to avoid vascular stenosis or occlusion after PTA and(More)
In this presentation BANG polymer-gel dosimetry using magnetic resonance imaging (MRI) is applied to densely ionizing radiation such as carbon ion beams. BANG polymer-gels were irradiated with monoenergetic 12C ions at an energy of 205 MeVu(-1). The irradiation of the gels with doses up to 100 Gy were performed at the radiotherapy facility of the GSI,(More)
