背景资料：本研究旨在探讨Cavalieri法在磁共振图像（MRI）上估计乳房假体体积的准确性和可重复性。取5 mm厚的连续切片，分别用流体置换法和三维后处理软件测量和估计假体体积。结果：Cavalieri法与真实的乳房体积之间无显著性差异（p> 0.05），3位术者用Cavalieri法估计乳房体积，并与术者的估计值进行比较。结论：本报告描述了一种快速、简单、准确和实用的方法，可以在不改变临床常规流程的情况下估计乳房假体的体积。得出的结论是，MRI与Cavalieri原则相结合是一种直接和准确的技术，可以安全地应用于估计乳房假体的体积在4分钟和34秒每个假体。
Background: The purpose of this study was to search the accuracy and reproducibility of the Cavalieri method for the estimation of the breast prosthesis volume on magnetic resonance images (MRI).Methods: Nine breast prostheses were scanned in axial and coronal section planes by MRI. The consecutive sections in 5-mm thickness were taken, after which the volumes of the prostheses were measured and estimated by means of the fluid displacement technique and three-dimensional post-processing software, respectively. The volumes of the prostheses also were estimated by three performers using the Cavalieri principle to check the accuracy and interobserver interrelation of the suggested techniqueResults: There were no significant differences between the Cavalieri estimate and the real volumes of the breast prostheses (p > 0.05), nor between the performers's volume estimates (p > 0.05). The orientation of the section planes did not affect the accuracy of the estimates (p > 0.05)Conclusions: This report describes a rapid, simple, accurate, and practical technique for estimating the volume of the breast prostheses without changing the routine process in the clinics. It was concluded that the combination of MRI with the Cavalieri principle is a direct and accurate technique that can be applied safely for estimating the volume of the breast prosthesis in 4 min and 34 s per prosthesis.
