Performance evaluation of upright CT and its application in the diagnosis of degenerative bone and joint diseases
Objective To evaluate the performance of upright X-ray computed tomography equipment including imaging capability,workflow and image quality,and to preliminarily explore its application value in degenerative bone and joint diseases.Methods Use a supine scanning device with the same hardware configuration as upright CT to perform a comparative evaluation of the imaging ability through phantom scanning.After approval by the Ethics Committee of our hospital,35 volunteers were recruited to perform upright scans,including 29 plain scans and 6 enhanced scans.Each volunteer was scanned for a certain area,recording parameters such as positioning time,scanning time and scanning dose.The data were compared with supine position scanning equipment to evaluate the rationality of the work process.After obtaining the imaging data,the image quality was evaluated using the Likert five component scale by a two person blind evaluation method.Obtain supine CT image data of two volunteers and compare the differences between supine and upright positions.Results The imaging ability of upright CT was equivalent to that of supine CT with the same configuration.The scanning process was reasonable,and the image quality was good.Through image comparison,significant differences were found in supine and upright images between patients with lumbar disc herniation and knee osteoarthritis.Conclusions Upright CT has good imaging ability,reasonable workflow,and clear images.It will be of great significance in the diagnosis of degenerative diseases of bones and joints.
