The value of a semi-automated program for volumetric measurements was tested in 53 patients with liver lesions. Three different radiologists performed 10 measurements on a liver lesion in each patient. The variances of the measurements were calculated. There was no difference in intra- and interoperator variance of the measurements. If the diameter of the liver lesion exceeded the slice thickness, the different measurements became more reliable and more reproducible. The semi automation of the volume measurements makes its use in daily clinical practice possible. Volume measurement can be interesting in the follow-up and evaluation of the treatment on tumor reduction. However further and more thorough investigation is needed to test the clinical usefulness of the program.
对53例肝脏病变患者测试了一种用于容积测量的半自动程序的价值。三位不同的放射科医生对每位患者的一个肝脏病变进行了10次测量。计算了测量值的方差。测量值的操作者内和操作者间方差没有差异。如果肝脏病变的直径超过切片厚度,不同的测量就会变得更可靠、更可重复。容积测量的半自动操作使其在日常临床实践中的应用成为可能。容积测量在肿瘤缩小治疗的随访和评估中可能会很有意义。然而,需要进一步更全面的研究来测试该程序的临床实用性。
