Lung cancer screening with CT can identify coronary artery calcium

Lung cancer screening with low-dose chest computed tomography (CT) may detect more than just lung cancer. As new research in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.231602 shows, these CTs can identify coronary artery calcium, a strong risk factor for coronary artery disease (CAD), in patients without cardiac symptoms.

Scientists develop color-coded X-rays to detect early disease

Medical imaging is no longer in Kansas, Toto, as a team led by Penn State researchers brings traditional black and white diagnostic images of X-rays and traditional CT scans into technicolor. The researchers developed novel contrast agents that target two proteins implicated in osteoarthritis, a degenerative joint disease commonly characterized as wear-and-tear arthritis.
