Estimation method for subcutaneous fat, bone and muscle volume in whole body calculate from cross-sectional image using MRI technique

本研究的目的是建立一种方法，从日本成年人从头部到足部的连续横断面图像中定量分析脂肪、肌肉和骨骼等结构的分布情况，特别是检查方法简单易行，可以估计脂肪膜的数量。测量项目为磁共振膀胱造影、形态计量学、水下体重、肢体体积、皮褶厚度。横断面图像采用MRI设备，在脂肪、肌肉、内脏和骨骼等结构似乎可以区分的情况下，从头到脚以2cm的距离拍摄。记录，然后将从头到脚的连续横截面图像用于胶片或磁带，以便利用图像处理设备，并根据脂肪、肌肉、骨骼和内脏等结构要求横截面面积。 关于我们 RA.根据结构和层间距离，由横截面积计算身体各部分的体积。按体积结构由稠度计算出各部位的重量。本文从测量项目和结构特征两个方面验证了日本人体成分的估算方法简便易行，并设计了各种统计参考物的体积与体重，即从头到脚的体积与体重之差为1%，肾静脉造影为2.5%分析了4例先证者在MRI法和Aqua法中用MRI肾静脉造影测量下肢容积的准确性，女性根据结构一致性估计体重的结果，误差为0.6%。本文认为，MRI方法根据肢体成分估计体重的准确性取决于骨骼和脂肪组织识别的准确性。我需要时钟时间来分析从头到脚的连续性横截面积，而不是预期的，并且提交已经晚了，因为数据已经采取了研究效果的报告书，并且没有设置收集它。少

A purpose of this study established approach to quantitave distribution condition of structure such as fat, muscle and bone from continuity transverse section image of from head to foot in Japanese adult got with MRI apparatus and was that in particular examined approach to be simple and easy of panniculus adiposus amount estimation. Measurement item is cystography of transverse section image of from head to foot by MRI,morphometry, underwater body weight, body extremity volume, skinfold thicness. As for the transverse section image, it was filmed from head to foot with 2 cm distance with the condition which structure such as adiposus fat, muscle, viscera and bone could seem to distinguish and using MRI apparatus. It was recorded, and continuity transverse section image of from head to foot was used for film or magnetic tape afterwards in order I utilized picture processing apparatus, and to demand cross sectional area according to structure such as adiposus fat, muscle, bone and visce … More ra. The volume of body each part was calculated from cross sectional area according to structure and slice distance. The weight of body each part was calculated from consistency according to structure by volume. It was examined that estimation approach was simple and easy of body composition for Japanese from measurement item and structure distinction volume of every kind statiscal referencewith weight was planned.It is volume of from head to foot and difference with body weight renal venography is 1% and is difference of 2.5% in lower extremities volume and shows bearing height of accuracy of volume measurement with MRI renal venography during MRI method and aqua as a result of having analyzed it about four proband of female. And error of 0.6% was recognized as a result of having estimated body weight from consistency according to structure. That accuracy of weight estimation according to body extremity composition by shell which was about these, MRI method was dependent on accuracy of identification of caro and adipose tissue was suggested. I needed clock time for analysis of continuity cross sectional area of from head to foot than expectation, and submission has been late because data a report book of study effect was taken, and to gather it up was not set.
