目的探讨多功能动态平板X线机在静脉肾盂造影检查中的应用价值.方法将540例进行静脉肾盂造影患者按随机数字表法分成多功能动态平板X线机组(300例)及普通平板X线机组(240例),并对两组图像质量、辐射剂量和检查时间进行比较分析.结果两组静脉肾盂造影图像质量比较差异无统计学意义(P＞ 0.05),多功能动态平板X线机组检查时间为(25.5±8.2)min,辐射剂量为(12.5±6.8) mAs,普通平板X线机组检查时间为(39.2±12.1) min,辐射剂量为(23.6±7.6) mAs,两组比较差异有统计学意义(P＜0.01).结论多功能动态平板X线机在静脉肾盂造影检查中能明显有效地降低辐射剂量和缩短检查时间,并能提高影像质量,在泌尿系造影中具有明显优势.

Objective To investigate the application value of multifunctional dynamic flat panel X-ray detector in intravenous pyelography.Methods Total 540 patients with intravenous pyelography were divided into multifunctional dynamic flat panel X-ray detector group (300 cases) and conventional flat panel X-ray detector group (240 cases) by random digits table method.Image quality,radiation dosage and examination time were analyzed and compared between the two groups.Results There was no statistical difference between the two groups in image quality (P ＞ 0.05).The examination time and radiation dosage was (25.5 ± 8.2) min and (12.5 ± 6.8) mAs respectively in multifunctional dynamic flat panel X-ray detector group and (39.2 ± 12.1) min and (23.6 ± 7.6) mAs in conventional flat panel X-ray detector group.The differences had statistical significance (P ＜ 0.01).Conclusions Multifunctional dynamic flat panel X-ray detector in intravenous pyelography can provide lower radiation dose,shorter examination time and higher image quality.It has obvious advantages in urography.
