双能量能谱CT分析体内尿酸结石的诊断价值
Diagnostic value of dual energy spectrum CT in uric acid calculus
摘要
Abstract
57 cases of patients were treated with dual energy spectral CT scanning in a retrospective study and the effective atomic number and histogram were adopted to determine the stone composition.The results of infrared spectroscopy were used as reference standards.The sensitivity for detecting pure uric stones,pure non-uric acid stones and mixed stones were 100%,91.7%,97.0%,respectively;with specific degree 100%,97.4%,95.7%,respectively;with positive predictive value 100%,84.6%,98.5%,respectively;and the negative predictive value were 100%,98.7%,91.7%,respectively. Dual energy spectrum CT through effective atomic number combining histogram has high accuracy in the diagnosis of pure uric acid stones, pure non-uric acid stones and mixed stones and can accurately distinguish uric acid stones and non-uric acid stones in vivo.关键词
