The last few years have witnessed extraordinary advances in medical imaging. The new digital methods, such as CT or MRI, share the common characteristic of providing three-dimensional volume data. The urgent need for efficient techniques for visualizing volume data has recently been recognized not only in diagnostic medicine, but also in computer-assisted(More)
UNLABELLED It is unknown whether model of renarrowing after beta-radiation for in-stent restenosis (ISR) is influenced by the type of geographic miss (GM). METHODS In 166 ISR treated with Galileo, serial quantitative coronary angiographic analysis was done. Minimal lumen diameters and lengths were measured for (1) stent, (2) peri-stent subsegments(More)
BACKGROUND The aim of our study was to test the impact of acute lumen overdilation on neointimal hyperplasia and late lumen size after vascular brachytherapy for in-stent restenosis (ISR). METHODS Forty-seven ISR lesions located in 47 coronary arteries in 44 consecutive patients underwent beta brachytherapy with serial intravascular ultrasound studies.(More)
INTRODUCTION Vascular brachytherapy reduces recurrence after treatment of in-stent restenosis. However, there are still failures. The aims of the study were to investigate the relationship between two distinct dose prescriptions and the calculated dose delivered versus binary angiographic restenosis. METHODS AND MATERIALS Fifty-five lesions in 47 patients(More)
AIM The incidence of restenosis within stented segment after intravascular brachytherapy with recommended dose prescription protocols is up to 25%. Therefore, we designed a randomized trial comparing recommended dose prescription protocol with dosing adjusted for the source-to-target distance. METHODS Fifty-one in-stent restenosis (ISR) lesions in 48(More)
