- Abstract:
- Abstract: Objective To investigate the value of high-frequency ultrasound (HFUS) and dual-energy CT (DECT) in the screening for early joint lesions of asymptomatic hyperuricemia (AH). Methods Fifty patients with AH (with a total of 300 joints) were examined with HFUS and DECT. The urate crystal, bone erosion, joint effusion, synovial thickening and the color Doppler findings at lesions in patients with AH were observed and compared. Results Among the 300 joints, 13.00% (39/300) of the joints were found in the HFUS examination, and 17.67% (53/300) of the joints were found in the DECT detection. The positive rates of crystal deposition, bone erosion, joint effusion and synovial pannus detected with HFUS were 8.33%, 0.67%, 6.67% and 4.66%, respectively. The positive rates of crystal deposition, bone erosion and joint effusion detected with DECT were 16.33%, 3.67% and 4.00%, respectively, and synovial hyperplasia could not be detected with DECT. The positive rates of crystal deposition and bone erosion detected with DECT were higher than those detected with HFUS, and the differences were statistically significant. However, compared with DECT, HFUS achieved a higher positive rate of joint cavity effusion, and the difference was statistically significant. Conclusion Both HFUS and DECT can be used to screen the early joint lesions of AH. DECT is more advantageous than HFUS in detecting urate crystal and bone erosion. However, HFUS is superior to DECT in detecting the early joint effusion and understanding synovial membrane.
