Volumetric modulated arc radiosurgery for brain metastases from breast cancer: A single-center study.

Background: Whole-brain radiation therapy (WBRT) and stereotactic radiosurgery (SRS) are two treatment modalities commonly utilized to treat brain metastases (BMs).

Aim: The purpose of this study is to analyse retrospectively the local control and survival of patients with BMs of breast cancer (BC) treated via radiosurgery using Volumetric Modulated Arc Therapy (VMAT-RS).

Methods: 18 patients with 41 BMs of BC and treated by VMAT-RS were studied.

Antiseizure medication for brain metastasis-related epilepsy: Findings of optimal choice from a retrospective cohort.

Objective: To analyze the prevalence of antiseizure medication (ASM) in patients with brain metastasis-related epilepsy (BMRE) treated with radiosurgery and the relationship between ASM and psychiatric comorbidity.

Material And Methods: This is a cross-sectional observational design study with retrospective review of medical records of all patients with brain metastases treated with volumetric modulated arc therapy radiosurgery (VMAT-RS) between 2012 and 2018 in a tertiary oncology center. We included those patients with BMRE, analyzing the clinical and demographic data, with special attention to psychiatric comorbidities and the use of ASM.

Non fluoroscopic ablation of different arrhythmic structures in an electrophysiology unit. Assessment of efficiency and security.

Background: Electroanatomical mapping systems (EMS) reduce fluoroscopy dose for the ablation. Higher costs and longer procedure times are the drawbacks associated with EMS. Our objective was to validate the efficiency of the EMS.

Machine Learning Techniques Applied to Dose Prediction in Computed Tomography Tests.

Increasingly more patients exposed to radiation from computed axial tomography (CT) will have a greater risk of developing tumors or cancer that are caused by cell mutation in the future. A minor dose level would decrease the number of these possible cases. However, this framework can result in medical specialists (radiologists) not being able to detect anomalies or lesions.

Ionizing Radiation Measurement Solution in a Hospital Environment.

Ionizing radiation is one of the main risks affecting healthcare workers and patients worldwide. Special attention has to be paid to medical staff in the vicinity of radiological equipment or patients undergoing radioisotope procedures. To measure radiation values, traditional area meters are strategically placed in hospitals and personal dosimeters are worn by workers.

Volumetric-modulated Arc Therapy Lung Stereotactic Body Radiation Therapy Dosimetric Quality Assurance: A Comparison between Radiochromic Film and Chamber Array.

Introduction: The aim of this work is to verify the use of radiochromic film in the quality assurance (QA) of volumetric-modulated arc therapy (VMAT) lung stereotactic body radiation therapy (SBRT) plans and compare the results with those obtained using an ion chamber array.

Materials And Methods: QA was performed for 14 plans using a two-dimensional-array seven29 and EBT3 film. Dose values per session ranged between 7.

Results of 1 year of clinical experience with independent dose calculation software for VMAT fields.

It is widely accepted that a redundant independent dose calculation (RIDC) must be included in any treatment planning verification procedure. Specifically, volumetric modulated arc therapy (VMAT) technique implies a comprehensive quality assurance (QA) program in which RIDC should be included. In this paper, the results obtained in 1 year of clinical experience are presented.
