Dual-energy computed tomography angiography: virtual calcified plaque subtraction in a vascular phantom
BACKGROUND Material decomposition of dual-energy computed tomography (DECT) enables subtraction of calcified plaque. PURPOSE To evaluate the accuracy of lumen area measurement in calcified plaque by subtraction of DECT and to determine the effect of contrast material concentration, lumen diameter, density, and thickness of calcified plaque for the measurement. MATERIAL AND METHODS Vessel ph...

Background: This study set out to evaluate the utility of cerebrovascular virtual non-contrast (VNC) scans. Materials and Methods: Conventional non-contrast (CNC) and dual-energy computed tomography angiography (DE-CTA) head scans were conducted on 100 subjects, of which 46 were normal, 15 had parenchymal hematomas of the brain, 13 had ischemic infarction, 22 had tumors, and 4 had calcified les...
متن کاملnon-calcified coronary artery plaque characterization by dual energy computed tomography (dect)
background one of the most important causes of mortality in developed and developing countries is coronary artery disease. coronary artery disease (cad) may develop by deposition of lipid, fibrous or calcified debris on the surface of the coronary artery lumen. fibrous plaque and calcified plaque may cause substantial stenosis of coronary arteries leading to ischemia of heart muscle while lipid...

متن کاملCompound analysis of gallstones using dual energy computed tomography--results in a phantom model.
PURPOSE The potential of dual energy computed tomography (DECT) for the analysis of gallstone compounds was investigated. The main goal was to find parameters, that can reliably define high percentage (>70%) cholesterol stones without calcium components. MATERIALS AND METHODS 35 gallstones were analyzed with DECT using a phantom model. Stone samples were put into specimen containers filled wi...
