Using a stroke rehabilitation device that converts an individual's thoughts to electrical impulses to move upper extremities, stroke patients reported improvements in their motor function and ability to perform everyday activities. Results of the study were presented at the Radiological Society of North America Annual Meeting (RSNA 2013).

Healthy adults who consumed energy drinks high in caffeine and taurine had significantly increased heart contraction rates one hour later, according to a study presented at the the Radiological Society of North America Annual Meeting (RSNA 2013).


Healthcare providers must reinforce their efforts to monitor and visualize dose levels from radiology examinations to enhance patient safety and meet new regulatory demands. There is also a need to justify and optimize the usage of radiation dose to find a balance between safer practice, image quality and lower dose – all for the benefit of the patient. Implementing tools for automatic and continuous follow up of radiation dose is at the forefront of meeting these challenges.

The significant increase in radiation exposure and uncertainty regarding the risk of cancer have raised concerns leading to a recent change of direction within medical imaging. Several initiatives to lower dose levels are being established and many healthcare providers have initiated dose reduction programs to guard patient safety and to comply with new regulations. 

The radical increase in patient exposure to radiation from medical imaging over the last two decades has created great concerns about its inherent risks. Today, one of the highest priorities on many hospital agendas is to break this trend by achieving improved control of the radiation exposure to their patients.

Researchers say they have achieved enough coherence of the magnetic moment inherent in the defects of miniscule diamond fragments to harness their potential for precise quantum sensors in a material that is biocompatible.
