Coronary artery anomalies—both benign and malignant—can be detected with relatively high accuracy on noncontrast-enhanced coronary artery calcium scoring (CCS) studies, according to a study published in the May issue of Academic Radiology.Health ImagingHealth Imaging...
Valley offers the latest cardiac CT imaging to assess your heart health. This noninvasive test can detect and evaluate heart conditions like coronary artery disease (CAD),aortic diseaseand more. Ourcardiac imagingteam also specializes in incorporating artificial intelligence and machine learning with car...
Figure 3. CT calcium scoring is possible at low-radiation doses in most patients; a: an average sized man was scanned at 120 kV. The scanner software selected a tube current of 90 mAs based on body size and the resulting radiation exposure was 0.44 mSv; b: in a woman with a body ma...

CT Coronary Calcium Scoring This single breath-hold, non-invasive, and fairly inexpensive CT scan can assess the extent of coronary artery calcium. Calcium scoring can help identifyatherosclerosis(fatty buildup in the wall of the heart arteries). This helps to determine your treatment and risk-red...
