The authors analyzed 177 pulmonary nodules using thin-section computed tomography (CT), calculating the representative CT number (RCT#) from a computer printout. None of the 96 malignant nodules had an RCT# greater than 151 H. Of the 81 benign nodules, 14 were shown to be calcified by conventional radiography and had an RCT# ranging from 763 and 1,023 H. Thirty had an RCT# greater than 200 H; this included 24 which showed no calcification on conventional tomograms. The remaining 37 benign nodules had an RCT# less than 200 H; 6 of them were hamartomas, including 2 which were diagnosed as such due to their fat content.
作者使用薄层计算机断层扫描（CT）分析了177个肺结节，从计算机打印输出中计算出代表性CT值（RCT#）。96个恶性结节中没有一个的RCT#大于151 H。在81个良性结节中，14个经传统放射照相显示为钙化，其RCT#范围为763至1023 H。30个结节的RCT#大于200 H；其中24个在传统断层扫描上未显示钙化。其余37个良性结节的RCT#小于200 H；其中6个是错构瘤，包括2个因其脂肪含量而被诊断为此类的错构瘤。
