The authors analyzed 177 pulmonary nodules using thin-section computed tomography (CT), calculating the representative CT number (RCTnumber) from a computer printout. None of the 96 malignant nodules had an RCTnumber greater than 151 H. Of the 81 benign nodules, 14 were shown to be calcified by conventional radiography and had an RCTnumber ranging from 763 and 1023 H. Thirty had an RCTnumber greater than 200 H; this included 24 which showed no calcification on conventional tomograms. The remaining 37 benign nodules had an RCTnumber less than 200 H; 6 of them were hamartomas, including 2 which were diagnosed as such due to their fat content.
