Abstract

Abstract: PURPOSE: To explore the clinical application value of energy spectrum CT single energy imaging in displaying lesions of jawbone osteomyelitis. METHODS: Energy spectrum CT imaging data of 12 patients diagnosed with jaw osteomyelitis in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine were retrospectively analyzed. GSI Viewer software was used to reconstruct the images at 40, 50, 60, 70, 80 keV single energy values. The CT values and SNR values of each single energy group in the lesion area were analyzed to obtain the optimal keV value, and compared with enhanced MRI images to evaluate the display of energy spectrum CT imaging on surrounding soft tissues. PASW Statistics 18.0 software package was used for data analysis. RESULTS: Different single energy values had significant impact on CT values(P<0.01), and the image quality was relatively good at 70 keV. Energy spectrum CT imaging could display the involvement of surrounding soft tissues. CONCLUSIONS: Energy spectrum CT single energy image under the condition of 70 keV has the best display effect on the lesions of jawbone osteomyelitis, which can reflect the surrounding soft tissue situation, with certain diagnostic efficacy for jawbone osteomyelitis.
