Imaging Vessel Wall Identifies Vulnerable Plaque in CTA Calcium score does add prognostic value to standard risk factors and serum markers, imaging the vessel wall directly may be helpful to identify non-calcified plaque and guide therapy, according to a study published in the July issue of the American Journal of Roentgenology. “Identification of small-volume soft plaque is the crux of coronary artery disease management. Investigators have repeatedly shown that acute coronary syndromes most frequently result from the rupture of these small plaques, which are generally not flow-limiting, do not cause stenosis, and may not be calcified,” wrote the authors of a study conducted by clinicians at Radiology Imaging Associates in Englewood, Colo., and Nighthawk Radiology Services in Coeur d’Alene, Idaho. Interpreting physicians at the practices reviewed 729 consecutive CT calcium scoring examinations conducted immediately prior to CT angiography (CTA), which were performed over a two-year period. The mean age of the patient cohort was 56, and 32 percent of the study group were female. To read the entire article from Health Imaging News, please click here. |
