An algorithm that was developed with the help of artificial intelligence could help physicians diagnose myocardial infarction more quickly and accurately, according to the results of research published in Nature Medicine.“For patients with acute chest pain due to a heart attack, early diagnosis and treatment saves lives,” Nicholas Mills, PhD, British Heart Foundation Professor of
Using noninvasive 18F-sodium fluoride PET and coronary CTA to detect “hot” disease in arteries, researchers were able to predict which patients with recent MI would have recurrent coronary events. PET “is often used in cancer; it uses positrons to produce a signal so you can see externally the biology of what’s going on in the body without inserting catheters,” David
