Dual-energy computed tomography (CT) was used to study apparently noncalcified pulmonary nodules in 19 patients. We obtained both high- and low-voltage images during one CT scan study using a special CT apparatus, and four of 11 benign lesions were diagnosed as benign by measurement of the CT number. Moreover, this particular CT apparatus was useful in judging the presence or absence of calcification in pulmonary nodules.
采用双能计算机断层扫描(CT)对19例疑似非钙化肺结节患者进行研究。我们使用一种特殊的CT设备在一次CT扫描研究中获取了高电压和低电压图像,11个良性病变中有4个通过CT值测量被诊断为良性。此外,这种特殊的CT设备有助于判断肺结节中钙化的有无。
