The qualitative assessment of the echogenicity of the renal cortex and the medulla is one of the most important diagnostic criteria in the assessment of diffuse renal parenchymal disease. It is of interest to complete this assessment by quantitative data. The echogenicity of the cortex and medulla was quantitatively analysed in digitized images. The coefficient of variation of repeated measurements was 0.83% and the coefficient of variation made by two different individuals was 2.03%. The influence of furosemide on the echogenicity of the renal parenchyma was measured in 4 healthy adults. The echogenicity of the renal cortex is after 3 and 6 min significantly increased, while the echogenicity of the medulla remained unchanged. Our study shows that a precise measurement of echogenicity in renal parenchyma is possible. Under the influence of furosemide there will be a significant increase in the echogenicity of the renal cortex.
肾皮质和髓质回声性的定性评估是弥漫性肾实质疾病评估中最重要的诊断标准之一。通过定量数据完成该评估很有意义。对数字化图像中的皮质和髓质回声性进行了定量分析。重复测量的变异系数为0.83%，两名不同个体测量的变异系数为2.03%。在4名健康成年人中测量了呋塞米对肾实质回声性的影响。肾皮质的回声性在3分钟和6分钟后显著增加，而髓质的回声性保持不变。我们的研究表明，对肾实质回声性进行精确测量是可行的。在呋塞米的影响下，肾皮质的回声性将显著增加。
