Biomarkers on PET, MRI show breast cancer risk
January 23, 2020 -- In a finding they described as "unexpected," researchers used PET and MRI to discover that women with a malignant tumor in one breast have lower levels of certain biomarkers in the contralateral, healthy breast. Results were published in the January edition of the Journal of Nuclear Medicine.  Discuss
High calcium density on CCTA linked to lower risk of ACS
January 22, 2020 -- High levels of plaque calcification on coronary CT angiography (CCTA) scans were associated with a lower risk of acute coronary syndrome (ACS) and adverse cardiac events for individuals suspected of having heart disease in an international study published online January 22 in JAMA Cardiology.  Discuss
Deep learning of x-rays helps predict pulmonary blood flow
January 22, 2020 -- A deep-learning algorithm that analyzed chest x-rays was able to predict pulmonary to systemic blood flow just as well as clinicians. The finding could give healthcare providers a better way to determine which patients with congenital heart disease require intervention, according to a January 22 article in JAMA Cardiology.  Discuss
