双能量CT成像技术在痛风患者筛查中的临床应用及价值评估
Clinical application and value evaluation of dual energy CT imaging in the screening of patients with gout
摘要
Abstract
Objective:To study the preliminary application of dual energy CT imaging in the screening of patients with gout,e-valuate the early diagnostic value in gout. Methods:To select the first hospital in qiqihar city for a total of 122 patients with acute joint pain clinic,to pass through the clinical diagnosis of 98 cases of gout patient,by the hospital ethics committee ap-proval of patients included in the study,analyze the imaging features and clinical data,and the control group of 24 cases of gout patients,all patients' feet/hands do DECT non enhanced scan,thin layer after restructuring would transmit the original data to choose MMWP workstation Dual Energy gout software,image post-processing,gout recognition analysis DECT overall sensitivity and specificity of diagnosis of gout,compare gout patients and patients with uric acid salt deposition part number and differ-ence;Using t test and χ2 test,Fisher exact probability statistical analysis. Results:comparing two groups of gender and age,there was no statistically significant difference (Page=0.236,Pgender=0.613);DECT overall sensitivity and specificity for the diagnosis of gout was 91.84% and 87.50% respectively;Gout group detection rate compared with the control group,with significant difference sta tistically significant (P=0.000). Conclusion:Dual-source CT gout identification technology is a new method of imaging diagnosis, with high sensitivity,non-invasive and repeatability. DECT has a good ability to show urate crystal deposition, and has a higher detection rate in patients with gouty arthritis. DECT can be used as a routine inspection project of gout screening and has high clinical application value.关键词
