''Radiation doses for computed tomography (CT) vary substantially across patients, institutions, and countries. Ionizing radiation is a known carcinogen, and CT radiation is associated with increased cancer incidence. Therefore, it is important to minimize ...'

''Large differences in radiation doses used for CT scans are mainly due to how the scanners are used by medical staff rather than differences in the patients scanned or the machines used, finds a study in The BMJ today. Setting more consistent dose ...'

''Extremely obese people are needing a far higher dose of radiation during x-ray examinations than people of normal weight, increasing their risk of cancer, new research has shown. The University of Exeter and Musgrove Park Hospital, Taunton, led the ...'

''There's a new modality in radiology, one that takes advantage of digital radiography (DR) and reflects the tenets of value-based medicine low cost, high information and low radiation dose to patients. The FDA has not cleared this modality, but ...'

''A concept for a novel X-ray microscope promises three-dimensional images of delicate objects like biological cells using a thousand times less damaging radiation than conventional methods. The novel microscope would allow to image whole cells at high ...'

''New injector technology for CT, MRI and angiography systems helps reduce dose and automatically records contrast used for the patient ...'

''Investigators of the COSMOS (Continuous Observation of SMOking Subjects) study show good compliance and patient survival outcomes using a 5-year low-dose computed tomography (LDCT) screening protocol in individuals at high-risk of developing lung cancer. ...'

''In showcasing the 510(k) pending Revolution CT* scanner, GE Healthcare introduces an ultrafast scanner with not only impressive image quality and reduced dose, but also technology that can capture a motion free image of the human heart in just one beat. ...'

''Philips (NYSE:PHG) landed 510(k) for its next-gen AlluraClarity, a live image X-ray system with lower radiation doses and more sophisticated software, according to a press statement. This imaging software, called ClarityIQ, will be offered as an ...'

''Dentists have been warned not to buy a handheld x-ray machine which exposes patients to 10 times the recommended dose of radiation. The cheap imported devices could also pose a significant risk to dentists and nurses, health officials said. The ...'
