摘要: Purpose: To determine the clinical utility of dual-energy computed tomography (CT) in evaluating solitary pulmonary nodules (SPNs). Materials and Methods: This study was approved by institutional review board, informed consent obtained. CT scans were obtained before 3 minutes after contrast material injection 49 patients (26 men, 23 women; mean age, 60.39 years ± 12.24 [standard deviation]) using a scanner with technique. Image sets that included nonenhanced weighted average, enhanced virtual nonenhanced, iodine-enhanced images reconstructed. numbers SPNs on average compared, image degree enhancement compared. Diagnostic accuracy for malignancy number On image, size calcifications compared those th...
