研究目的:

拟收集痛风患者的患病部位CT普通扫描资料,并分别使用常规算法和新算法进行图像重建,得到常规痛风算法图像(current uric acid image, CUA)、新痛风算法图像(improved uric acid image, IUA),进行超声检查得到超声检查(ultrasound ,US)结果,以临床根据ACR/EULAR标准作出的最终诊断结果为金标准,对比CUA、IUA、US三种诊断方法之间对不同病程、不同部位痛风疾病的诊断效能,具体分析最新的能谱CT痛风算法在痛风诊断方面的优势与不足,以期对痛风患者的临床诊断提供可靠证据。  

Objectives of Study:

The general CT scanning data of gout patients were collected, and the conventional algorithm and the improved algorithm were respectively used for urate image reconstruction. The current urate spectral image (CUA) and the improved urate spectral image (IUA) were obtained. ultrasound was performed to obtain the results of ultrasound (US). The final diagnosis result based on the ACR/EULAR criteria was taken as the gold standard. The diagnostic efficiency of CUA, IUA and US for gout disease in different stages and different parts was compared. The advantages and disadvantages of the latest spectral CT gout algorithm in the diagnosis of gout are analyzed in order to provide reliable evidence for the clinical diagnosis of gout patients.
