摘要
目的:探讨MSCT灌注成像在肾脏检查的初步临床应用。材料和方法:采用16排螺旋CT及灌注软件对32例双侧肾脏和12例单侧肾脏进行灌注扫描,对比剂为优维显(300mgIml)50ml,注射速度4mls。结果:32例双侧肾脏皮质或髓质的同一灌注指标无明显差异,但同侧肾脏皮质和髓质的同一灌注指标明显不同。一侧肾脏切除后,对侧肾脏的灌注指标变化明显。结论:MSCT灌注成像实现了肾脏血流的定量研究,可直观评价肾组织微循环的血液动力学变化。
Purpose: To evaluate the primary application of MSCT perfusion in kidney. Materials and Methods: Renal tissue perfusion was performed in 32 cases of bilateral kidneys and 12 cases of unilateral kidneys by applying MSCT and perfusion software with 50ml Ultravist (300mgI/ml)and 4ml/s injection flow. Results: Perfusion values in the cortex or medulla of bilateral kidneys of the 32 cases were not obviously different from each other respectively (P>0.05) but in the same kidneys, the perfusion values in the cortex showed great difference from those in the medulla (P< 0.05). After one side of the kidneys was removed the perfusion value for the other reserved one altered significantly. Conclusion: MSCT perfusion imaging provides quantitative information about renal blood flowing and effectively evaluates the hemodynamic change in renal tissue.
