AuntMinnie | For surveillance of previously detected lung nodules, CT radiation dose can be cut to approximately 3% of the original exam dose, concludes a new study in the September edition of the American Journal of Roentgenology. The dose savings are important because lung cancer screening...
AuntMinnie | Using CT to measure cardiac fractional flow reserve (FFR) -- measuring the shape and speed of blood flow in the heart and coronary arteries -- is a potential game changer that could turn everyday coronary CT angiography (CCTA) scans into a one-stop cardiac...
DiagnosticImaging | Increasing use of CT scanning in emergency departments has corresponded with fewer hospital admissions, according to a new study published online in the Annals of Emergency Medicine. A team of researchers led by Keith Kocher, MD, of the University of Michigan, assessed emergency department...
DiagnosticImaging | A study assessing CT angiographs of nearly 25,000 patients presumed to be free of coronary artery disease (CAD) has shown both obstructive and nonobstructive forms of the disease to increase the risk of death. The study, published August 16 in the Journal of the...
DiagosticImaging | Using lower fixed-tube current or automatic exposure control techniques when performing adult and pediatric head CT scans can reduce radiation dose and ease concern about cancer risk, according to a recent study published in the Journal of the American College of Radiology. Head CTs...
