PURPOSE To study the efficacy of the integration of functional magnetic resonance imaging (fMRI) and diffusion tensor imaging tractography data into stereotactic radiosurgery clinical practice. METHODS AND MATERIALS fMRI and tractography data sets were acquired and fused with corresponding anatomical MR and computed tomography images of patients with(More)
CyberKnife frameless image-guided radiosurgery has become a widely used system for parenchymal extracranial lesions. Gold fiducials are required for the planning and aiming of CyberKnife therapy. We report our initial experience and describe the technique of positioning tumor markers, under CT guidance. We conducted a retrospective review of 105 patients(More)
BACKGROUND Stereotactic radiosurgery/radiotherapy procedures are known to deliver a very high dose per fraction, and thus, the corresponding peripheral dose could be a limiting factor for the long term surviving patients. The aim of this clinical study was to measure the peripheral dose delivered to patients undergoing intracranial Cyberknife treatment,(More)
PURPOSE Pregnancy during radiosurgery is extremely rare in clinical practice. We report fetal dose results during CyberKnife radiosurgery for a brain tumor in pregnancy. METHODS AND MATERIALS A 26 year old pregnant woman with a rapidly growing deep-seated grade-III glioma was treated during the third trimester of gestation using CyberKnife. Ultrasound(More)
Palladium-103 is a low energy photon emitter available for permanent interstitial implantation. Pd-103 has energy and safety characteristics similar to Iodine-125, but its initial peripheral dose rate is approximately three times greater. This may provide improved control of rapidly proliferating tumors. At the Westchester Campus of New York Medical(More)
Intracoronary irradiation emerges as a promising method in a variety of restenosis prone coronary lesions. We report the acute and long-term clinical, angiographic, and ICUS follow-up of a patient who underwent a successful angioplasty with stent placement in a chronic coronary occlusion with adjuvant gamma-intracoronary radiation.
