Abstract:
Objective To assess the value in detecting the tracheobronchial tree invasion by central lung cancer (CLC)using MSCT axial images and 4 kinds of images post-processed techniques.Methods 38 cases with CLC identified by fibrobrochoscopy or operation were scanned using MX8000 scanner with slice thickness of 3.2 mm, overlapping interval of 1.6 mm, pitch of 1.0. Multiplanar reformation(MPR), shaded surface display(SSD), volume rendering (VR) and virtual endoscopy(VE) were performed in all cases. Two radiologists assessed the invasion of tracheobronchial tree by CLC together.The imaging findings were compared with the data of surgery in 12 cases who were undergone operation.Results 38 cases of CLC, 0 grade to Ⅳ grade were assessed in 0,8,14,11 and 5 cases respectively by MSCT axial images, while in 0,10,11,12 and 5 cases by MSCT post-processing images. The concordance rate was 75% for MSCT axial images(n=9), and 100% for MSCT post-processing images(n=12) among 12 cases performed operation(? 2 test,? 2=6.0,P
