Radiology News and Research

RSS

Radiology is the medical specialty directing medical imaging technologies to diagnose and sometimes treat diseases. Originally it was the aspect of medical science dealing with the medical use of electromagnetic energy emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging.

American Heart Association recognizes 2,671 health care organizations for commitment to cardiovascular patient care

The American Heart Association, a relentless force for a world of longer, healthier lives, has recognized 2,671 health care and emergency response organizations -; nearly 145 more than in 2022 -; for their commitment to improving health outcomes for cardiovascular patients through evidence-based efficient and coordinated care.
