NUS invention may lead to safer, cheaper x-ray imaging

2018 31 Oct

Scientists from the National University of Singapore (NUS) have developed novel lead halide perovskite nanocrystals that are highly sensitive to x-ray irradiation. When used as a scintillator material in x-ray imaging, these nanocrystals can reduce the required radiation dose to deliver higher resolution imaging. A crucial part of x-ray imaging... Read more

Mitigating radiation risk in medical imaging: expert opinion

2018 29 May

In medical imaging, the level of radiation dose and risk is varied but is generally low. Despite the low magnitude and high uncertainty of this risk, its possibility cannot be easily refuted. Therefore, given the moral obligation of healthcare providers, "first do no harm," there is an ethical obligation to mitigate this risk, says a report to... Read more

Utility of lead glasses and eye dosemeters in radiation protection

2018 17 Apr

The number of interventional procedures has expanded steadily over the last two decades as new interventions of increasing complexity have been developed. This increases the risk of the eye lens doses approaching or even exceeding the new annual radiation dose limit of 20 mSv set by the Ionising Radiations Regulations (IRR 2017), according to an article...

Balancing Radiation Doses

2017 14 Apr

According to a new study, radiation doses for common CT scans can be safely and effectively reduced and more consistently administered by assessing and comparing doses across hospitals. The study is published in JAMA Internal Medicine. See Also : Assessment of Radiation Dose Reduction Awareness Over the last decade, there has been a steady... Read more

Assessment of Radiation Dose Reduction Awareness

2017 21 Mar

The observed increase in the number of abstracts regarding radiation dose reduction in the interventional radiology community over the past 10 years has not mirrored the increased volume seen within diagnostic radiology, suggesting that increased education and discussion about this topic may be warranted, according to a review published in the journal...

Radiation Dose - Who Calibrates the Machines?

2016 01 Feb

Dose reduction programmes rely on hardware, software and the actions of healthcare staff and patients. But did you ever stop to wonder who ensures the accuracy of the imaging and radiation therapy machines? The University of Wisconsin Radiation Calibration Laboratory provides calibration services to around 60 percent of the U.S. medical physics market,... Read more

Lower Dose, Lower Contrast Possible for CTA Scans

2015 26 Dec

A CTA scan (a scan of the arteries) can be performed with a contrast medium volume reduction of up to 75 percent and up to 50 percent reduction in radiation dose, according to a new study from the University of Twente in Enschede, Netherlands. Researchers say the study's results can almost directly be applied in hospitals today, thus providing enormous... Read more

RSNA15: Gaming Tech Creates Better X-Rays

2015 01 Dec

Researchers have developed software for the Microsoft Kinect gaming console that measures body-part thickness and checks for motion, positioning and beam adjustment immediately before x-ray imaging. The goal is to have the best quality x-rays at the lowest dose possible without repeating images, the researchers explained. Their feasibility study was... Read more

Study: Reduced PET Tracer, More Scans

2015 03 Nov

Latest advances in PET scanning technology make it possible to reduce radiation dose for both patients and medical staff by up to 30 percent, allowing an addition of 100 scans a year at Central Manchester University Hospitals. A recent study by scientists at Central Manchester University Hospitals NHS Foundation Trust and The University of Manchester... Read more
