Abstract:
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.
