To evaluate the diagnostic value of digital flat-panel radiography in uroradiology the i. v. urograms of patients who had been examined with computed radiography and digital flat-panel radiography were compared regarding image quality.
50 patients who underwent clinically indicated i. v. urography were examined with digital flat-panel radiography and computed radiography. In order to avoid unnecessary double exposure to X-rays, patients were examined either by flat-panel or computed radiography before injection of contrast media. Each further clinically indicated exposure after administration of contrast media was done by alternating the other examination technique. The digital images were compared by 4 radiologists regarding image quality for the detection of defined anatomic structures.
Digital flat-panel radiography showed an image quality of the liver, spleen and both kidneys that was similar to computed radiography. The urinary tract, lumbar spine, pelvis and psoas muscle were significantly better visible on flat-panel radiography images.
Compared to computed radiography there is no loss of image information by using digital flat-panel radiography in uroradiology. On the contrary, some anatomic structures on abdominal survey images show better image quality. In conclusion, digital flat-panel radiography has the potential to replace computed radiography in uroradiologic examinations.
为评估数字平板X线摄影在泌尿系统放射学中的诊断价值，对采用计算机X线摄影和数字平板X线摄影检查的患者的静脉肾盂造影图像质量进行比较。
对50例行临床指征静脉肾盂造影的患者进行数字平板X线摄影和计算机X线摄影检查。为避免不必要的X线双重照射，在注射造影剂前，患者采用平板或计算机X线摄影进行检查。造影剂给药后的每次进一步临床指征照射通过交替使用另一种检查技术进行。4名放射科医生对数字图像的定义解剖结构检测图像质量进行比较。
数字平板X线摄影显示肝脏、脾脏和双肾的图像质量与计算机X线摄影相似。平板X线摄影图像上尿路、腰椎、骨盆和腰大肌的显示明显更好。
与计算机X线摄影相比，在泌尿系统放射学中使用数字平板X线摄影不会丢失图像信息。相反，腹部平片图像上的一些解剖结构显示出更好的图像质量。总之，数字平板X线摄影有潜力在泌尿系统放射学检查中取代计算机X线摄影。
