A quantitative study of the normal position of the vessels of the posterior fossa was made. The centroid proved to be the most accurate reference point for vessels near the midline. The presence or absence of antomical constraints is important in evaluation in significance of an unusual measurement. A combination of unusual measurements which are not intercorrelated and which make sense anatomically suggests that a mass is present.
对后颅窝血管的正常位置进行了定量研究。结果证明,质心是中线附近血管最准确的参考点。解剖学限制因素的存在与否在评估异常测量的意义时很重要。一组互不相关且在解剖学上合理的异常测量结果提示存在肿块。
