PDFAbstract
Objective To study the clinical application value of computer-aided diagonosis in differentiating atypical adenomatous hyperplasia from adenocarcinoma insitu. Methods 125 cases of ground glass opacity detected by CT were diagonosized by self-designed soft, to compare the difference between AIS and AAH. Results There was no significant difference in lesion size between AIS and AAH (P>0.05). The peak and mean CT value of AAH were obviously lower than that of AIS,with significant difference (P<0.001). If the peak of CT value<-620,it was more likely to be AAH. In the CT histogram, doublepeak or multi-peak can except for the possibility of AAH. Conclusion Tissue components analysis basede on computer-aided diagonosis can perfectly identify AAH and AIS which appear as ground glass nodules.
