Ultrasonic image analysis aims to provide information related to tissue histology. Routine ultrasonography uses subjective criteria for analysis. Quantitation of the image is expected to aid diagnosis and may be helpful in follow-up of pathology. The authors describe normal findings in infant liver and kidney.
Texture parameters derived from the gray-level histogram and the first order statistics from the ultrasound images of the liver, right kidney, and a tissue-mimicking phantom in 50 newborn infants were studied.
A set of normal values for mean and standard deviation of the histogram for infant liver and kidney was established. Results of a time-related study indicate that in infants the liver is not a good internal standard for tissue characteristic comparison.
The method described and results obtained provide a basis of normality for further studies of pathology in infant renal and hepatic disease.
超声图像分析旨在提供与组织病理学相关的信息。常规超声检查使用主观标准进行分析。图像定量有望辅助诊断,并且可能有助于病理学随访。作者描述了婴儿肝脏和肾脏的正常表现。
研究了50例新生儿肝脏、右肾及组织模拟体模超声图像的灰度直方图纹理参数和一阶统计量。
建立了婴儿肝脏和肾脏直方图均值和标准差的一组正常值。一项与时间相关的研究结果表明,在婴儿中,肝脏不是用于组织特征比较的良好内部标准。
所描述的方法和获得的结果为进一步研究婴儿肾脏和肝脏疾病的病理学提供了正常基础。
