August 4, 2014 — A two-step decision tree analysis, incorporating Donabedian’s model, is a feasible process to evaluate and distill the many available quality standards, guidelines, recommendations and indicators in order to update national and international quality standards for radiation therapy, according to a study published in the July/August 2014 issue of Practical Radiation Oncology (PRO).

radiation dose management in medical imaging

Patient radiation dose safety has become the latest buzzword. With the emerging regulations and mandates, technologies and best practices, the radiation safety information pool has become convoluted with disparate and conflicting information. With numerous opinions and interpretations on radiation safety trends, best practices, regulation updates and studies, healthcare providers as well as the general public are experiencing difficulties filtering the true message in managing patient radiation dose away from the industry noise. Healthcare providers are constantly reviewing and assessing regulations, best imaging processes and the emerging technologies (automated dose management systems and dose management CT devices) promising to decrease or eliminate the chance of another sentinel event.

New research published in June issue of Global Heart (the journal of the World Heart Federation) show that there are no significant differences in the incidence or severity of atherosclerotic disease (narrowing of the arteries with fatty deposits) between ancient and modern people, showing that atherosclerosis is not just a disease of modern times. The journal included three articles [1,2,3] on the finding of the HORUS Study, which used CT scans from ancient mummies to compare arterial calcification caused by HORUS atherosclerosis.

August 4, 2014 — New technology in the form of a magnetically assisted remote-controlled catheter (MARC), which could allow physicians to see and assess brain tissue more clearly while treating a stroke, may hold promise, according to study authors who released their findings at the 11th annual meeting of the Society of NeuroInterventional Surgery (SNIS) in Colorado Springs, Colo.

Carestream Health has shipped more than 9,000 DRX detectors since launching the Carestream DRX-1, a wireless X-ray detector that quickly and affordably retrofits existing X-ray rooms or portable diagnostic imaging systems from computer radiography (CR) to digital radiography (DR) technology, or powers new DR rooms and mobile systems.

Anxiety regarding inconclusive cancer screening test results among some patients is real and is only natural. However, as evidenced by Gareen et al, published July 25 in Cancer, the incidence and effects of anxiety associated with false positive or other results of computed tomography (CT) lung cancer screening exams are far less than claimed by some in the medical community.
