Ankle Injuries in Children Don't Always Need an X-Ray

2015 23 Jul

Emergency physicians can safely reduce x-rays in children with injured ankles by as much as 23 percent, resulting in cost and time savings for patients, according to Canadian researchers who conducted a cost analysis of the Low Risk Ankle Rule (LRAR). The findings are reported in the journal Annals of Emergency Medicine . "Currently, x-rays are ordered... Read more

Studies Linking Cancer to Medical Imaging Radiation 'Flawed'

2015 02 Jul

Studies purporting to show a link between cancer and medical imaging radiation are flawed because of their reliance on an unproven statistical model, according to a report published in the journal Technology in Cancer Research & Treatment . “Although radiation is known to cause cancer at high doses and high-dose rates, no data have ever unequivocally...

Ensuring Radiation Safety in Clinical Trials

2015 18 Jun

Radiation experts in the UK have drawn up a new system to streamline approval process for setting up clinical trials involving radiotherapy and other forms of ionising radiation, such as PET scans. The new system provides a standardised way of assuring that exposure to ionising radiation during clinical trials remains within safe limits, while also... Read more

BIR Response to AMRC 'Choosing Wisely' Initiative

2015 28 May

The British Institute of Radiology (BIR) supports the Academy of Medical Royal Colleges work programme on the “ Choosing Wisely ” initiative to encourage doctors to consider the value of treatments and avoid “over medicalising” patients.   The BIR agrees that, for a range of reasons inappropriate clinical interventions are made which are not evidence...

Can EHR Decision Support Reduce Child Radiation Exposure?

2015 09 May

Risks associated with ionising radiation exposure are greater in children due to their longer life span and greater radiosensitivity. The good news is that according to researchers the risk can be significantly reduced with just a little bit of education. The finding is from a new study, “Point-of-care estimated radiation exposure and imaging guidelines... Read more

'Compressed Sensing': Reducing Radiation to One-Sixth

2015 28 Jan

A new mathematical discovery may reduce the number of measuring points to one-sixth of the present level, meaning reduced exposure to radiation and faster medical imaging diagnostics. The theory called compressed sensing enables compressive sampling without having to look at the raw data first, according to physicists at the University of Oslo (UiO)... Read more

Microwave Imaging: Better, Safer, Cheaper

2014 19 Dec

New research suggests that a cheaper, better and safer way to look for signs of breast cancer may be with microwaves. Neil Epstein, a NSERC CREATE I3T postdoctoral fellow at the University of Calgary in Canada and his colleagues -- engineering professor Paul Meaney of Dartmouth College's Thayer School of Engineering and Keith Paulsen, director...

#RSNA14: Many Chest X-rays In Children Are Unnecessary

2014 03 Dec

According to a study presented this week at the annual meeting of the Radiological Society of North America (RSNA), researchers at the Mayo Clinic have found that many children receive chest x-rays that may be unnecessary and have no clinical benefit.     "Chest x-rays can be a valuable exam when ordered for the correct indications," said Ann...

Proper Use of Cardiac Stress Imaging Could Cut Healthcare Costs

2014 23 Oct

Researchers from the New York University Langone Medical Center (New York, NY, USA) found that overuse of cardiac stress testing using advanced imaging technology has led to increasing healthcare costs in the US and unnecessary radiation exposure for patients. Their study, believed to be the first comprehensive investigation of trends in cardiac stress... Read more
