Abstract
Objective To explore the clinical value of new dual-source CT and dual-energy imaging in the analysis of the compositions of urinary calculi.Methods The compositions of urinary calculi in 45 patients were analyzed being scanned with new dual-source CT and dual-energy imaging.The compositions of urinary calculi was compared with the results from infrared spectrometry in vitro.The sensitivity and specificity of the composition of urinary calculi were analyzed with new dual-source CT.Results Dual-source CT could accurately distinguish nonuric acid stones from uric acid calculi,and its sensitivity and specificity were both 100.00％; the diagnosis sensitivity and specificity to phosphate stones were 93.10％ and 92.00％; the diagnosis sensitivity and specificity to cystine stones were 66.67％ and 97.90％; and the diagnosis sensitivity and specificity to calcium oxalate stones were 85.71％ and 100.00％.Conclusions Dual-source CT and dual-energy imaging can analyze the compositions of urinary calculi before treatment and has important significance in preventing and treating calculi.关键词
