Abstract:
Objective To investigate the application value of spiral CT imaging in diagnosing costal cartilage diseases. Methods CT volume scan with 1～7mm layer thinkness and 1～2.5mm layer distance was performed in 28 cases of costal cartilage diseases and 200 cases of controls. All of the original images were processed to form the thin layer reconstruction of low contrast and high contrast, and then the reconstructed images were transmitted to CT 3D work-station to perform the image reconstruction by MPR, MIP and SSD methods. The ability of different image techniques in displaying costal cartilage was compared, and costal cartilage pathological changes were analyzed. Results The CT scanning images of 228 cases could display the costal cartilage after the management of MPR, MIP and SSD, and the images managed with MIP and SSD were better. Among 28 patients with costal cartilage diseases, 13 cases of costal cartilage damage,9 cases of costal cartilage inflammation and 6 cases of costal cartilage malformation were found. Conclusion Spiral CT image could display the costal cartilage perfectly, was a new means of researching costal cartilage morphology in living body, and was the best imaging technique of researching costal cartilage disease without trauma.
