This ensures a substantial reduction of radiation exposure to physicians and patients, and the number of interoperative rescans, and does not negatively impact the available space in the room. ...
Fluoroscopy can assist screw placement; however, it increases the operative time and radiation exposure to the surgeon and other operation theatre staff. ...
MOTION study will quantify new technology’s impact on radiation exposure In December, Cleveland Clinic vascular surgeons successfully completed the first surgical case in the MOTION clinical trial of a new non-radiation-based surgical navigation platform for endovascular aortic interventions. ...
Continuous guidance of surgical tools relative to any pre and intra-operatively acquired 2D and 3D datasets assures reduced operative time, less radiation, and enhanced precision. Why should you consider easyNav for C-arm integration? Calibration and Navigation of other surgical tools such as drill and screwdriver with Reduced X-ray radiation ...
These complex procedures have required increased fluoroscopy times, resulting in higher radiation dose exposure to both patients and operators. It has also necessitated the development and use of an increased number of various-shaped catheters, sheaths, and wires to cannulate target vessels. ...
At the cellular level, definitely there are radiopathological changes in brain, however, very contrastingly, at the organism level ethological data show a better learned behaviour in mice post tritiated water exposure.Keywords: mice brain, maze, tritium, tritiated water exposure, learning behaviour, purkinje cells, pyknotic, cerebellum, radiopathological change, Swiss albino ...
According to the data obtained in this study the effective dose estimated for all cardiologists was lower than the monthly limits recommended by International Commission on Radiological Protection (ICRP).Keywords: staff dose, interventional radiography, occupational exposure, effective dose, occupational exposure, radiation ...
Studies indicated that oral administration of sesamol (SM), 1 hour prior to whole body gamma-irradiation (2–6 Gy), significantly protected cellular DNA in various tissues of mice, as evident from alkaline comet assay. Whole body exposure of mice to a sub-lethal dose of 6 Gy gamma radiation resulted in oxidative damage in various tissues of mice, and ...
POLY MVA, a commercially available health supplement containing α-lipoic acid palladium complex, was evaluated for its potential to enhance the repair of radiation-induced DNA damage. Treatment of human peripheral blood leukocytes with POLY MVA immediately after radiation exposure enhanced the repair of cellular DNA as revealed by comet ...
6 Gy), significantly protected cellular DNA in various tissues of mice, as evident from alkaline comet assay. Whole body exposure of mice to a sub-lethal dose of 6 Gy gamma radiation resulted in oxidative damage in various tissues of mice, and radiation-induced peroxidative damage and depletion of antioxidants such as GSH, GPx in tissues such as ...
POLY MVA, a commercially available health supplement containing α-lipoic acid palladium complex, was evaluated for its potential to enhance the repair of radiation-induced DNA damage. Treatment of human peripheral blood leukocytes with POLY MVA immediately after radiation exposure enhanced the repair of cellular DNA as revealed by comet ...
The main aims of this work are to identify the social-demographic profile of the workers based on stratification variables such as gender, age, and tasks performed by the workers, and to evaluate the annual collective doses of workers with potential risk of ionising radiation exposure at the workplace during the years 2004?2008. In this context, the knowledge of ...
Whole-body exposure of mice to gamma radiation leads to depletion of tissue antioxidant defence and damages the haematopoietic and gastrointestinal systems in mice. Administration of ascorbic acid-2-glucoside (AsAG) at a dose of 100 mg/kg body weight could prevent the radiation-induced reduction of total White Blood Cell (WBC) count and decrease ...
A computational tool was developed with the aim of evaluating radiation exposure levels corresponding to patients and other exposed people, such as medical staff or chaperones, during typical nuclear medicine procedures. ...
Many radiation workers believe that occupational exposures have the potential to interfere with their normal reproductive function. In this study, a total of 621 radiation workers (336 females and 285 males) who worked in hospitals/clinics in seven different provinces were randomly selected. ...
Although it is likely to be the greatest risk of radiation induced cancer, it may not constitute the greatest risk of death. ...
A comparison was made with the doses calculated by several similar programs for calculating patients' organ doses and the effective dose in medical X-ray examinations.Keywords: Monte Carlo dose assessment, X-ray diagnostics, Monte Carlo simulation, low radiation, patient exposure, radiation exposure, X-rays, absorbed doses, voxel ...
Population exposure to diagnostic and therapeutic ionising radiation is likely to increase worldwide, and this has raised concerns about the stochastic effects of low doses of radiation exposure. ...
The non-cancer disease mortality (1950-1995) among 27 011 medical diagnostic X-ray workers was compared to that of 25 782 other medical specialists employed between 1950 and 1980 to provide evidence of human non-cancer disease death produced by protracted and fractionated exposure to ionising radiation and assess the resultant non-cancer disease death risk. ...
The general purpose Monte Carlo N-Particle Radiation Transport Computer Code (MCNP4C) was used to calculate the equivalent dose to the person or people accompanying patients who have been exposed to radiation that was scattered from the patient. ...
