| Abstract:: |
| Objective To explore the effect of different scanning methods and different constructive arithmetic on displaying the anatomy of ostiomeatal complex(OMC). Methods Fifty-six patients undergoing paranasal sinus CT were divided into normal group (34 cases) and inflammation group (22 cases). According to scanning methods, all the cases reconstructed with soft tissue arithmetic were divided into coronary reforming group and coronary scanning group. Among 56 cases, 18 normal cases and 16 inflammation cases were reconstructed using high resolution arithmetic simultaneously. The imaging quality of OMC was assessed with different scanning methods and different constructive arithmetic. Results There are no significant difference between coronary reforming images and coronary scanning images in two groups. There are significant difference between high resolution arithmetic and soft tissue arithmetic in normal group, but not in inflammation group. Conclusions The information of axial images and coronary reforming images with 16-slice CT is superior to coronary scanning images on displaying the anatomy of OMC. High resolution arithmetic is better in displaying the tiny structure of OMC than soft tissue arithmetic in normal group. |
