| 目的 探讨数字化体层摄影在老年静脉肾盂造影应用中的价值。方法 应用直线轨迹8°/0.4s和数字化体层自动曝光三点技术:kV、mAs、ms,在透视检查后决定曝光条件即时抓摄泌尿系统的体层影像。结果 26例老年病人造影检查中,有19例腹部准备不充分,通过体层摄影全部消除了重叠伪影的干扰,使肾脏正常组织和病变得到清晰的显示,肾脏无明显异常征象20例,肾结石3例,肾积水1例,肾盂癌1例,肾钙化1例。诊断符合率达100%,曝光剂量降低了83.75%。结论 数字化体层摄影对提高老年IVP检查的诊断符合率和射线防护具有很高的价值,应该作为常规运用。 |

| Objective To study the application value of digitized tomography in the intravenous pyelography for the aged. Methods Linear digitized tomography: 8° and 0.4s was selected and three-point mode with automatic exposure control was applied to take an X-ray pyelogram immediately after performing a fluoroscopic exam. Results In 26 cases, the tissue and the intestines gas which overlap the kidneys about 19 cases were completely removed by the digitized tomography, the high resolution tomograms of the kidneys were acquired, 20 cases were normal, 3 cases had renal stone, 1 case had carcinoma of renal pelvis, 1 case was hydronephrosis, 1 case was renal cacification. The average X-ray exposure dose reduced from 80mAs to 13mAs. Conclusion The diagnostic accuracy of the X-ray pyelogram could be improved and X-ray exposure dose could be reduced by utilizing the digitized tomography and it should be used as routine technique in IVP. |
