Goutallier提出了根据CT影像上的肌肉是否出现脂肪束信号,对肩袖肌肉脂肪浸润进行了分级。后来Fuchs等证实了该分型系统采用MRI图像具有同样的可行性。该分型系统对肩袖的4块肌肉定义了5种程度的肌肉脂肪浸润。 Stage 0(0期):完全正常的肌肉,没有脂肪束。 Stage 1(1期):肌肉里面有一些脂肪束。 Stage 2(2期):脂肪...
Goutallier分类法是一种用于量化肩袖肌肉脂肪变性程度的分类系统,特别是在肩袖肌腱撕裂的情况下。该系统最初是在肩部CT中描述的,但它现在依然适用于磁共振(MRI)成像,并且最常用于磁共振成像。 Goutallier分类法主要基于受累肌肉的萎缩和脂肪变性的百分比进行分级。分级的严重程度依次增加,且分级越高,肩袖撕裂手术修复后...
分割肌肉和脂肪组织:利用计算机算法或手工勾画的方式,将MRI图像中的肌肉和脂肪组织进行分割,得到两者在横截面上的面积。 计算脂肪横截面积比率:将脂肪组织面积与肌肉组织面积之比称为脂肪横截面积比率,通常以百分数表示。 需要注意的是,MRI脂肪横截面积比率是一种常用的肌肉脂肪浸润评估方法,但其结果受到多种因素的影响...
Goutallier分类是一种视觉分级系统,用于定性评估脂肪浸润。Goutallier 分类最初用于在CT上对肩袖肌肉的脂肪变性进行分级,现已扩展到 MRI 和其他肌肉的评估。 参考文献: Mandelli F, Nüesch C, Zhang Y, Halbeisen F, Schären S, Mündermann A, Netzer C. Asse...
Methods Fatty infiltration of the rotator cuff muscles were classified based on the Goutallier grade (0-4) at 3 defined sections: section 1, original Y-view; section 2, level of suprascapular notch; and section 3, 3 cm medial to the suprascapular notch on MRI scans. Six subspecialist ...
Now the Goutallier classification is being used with magnetic resonance imaging (MRI). Not only is there debate on the validity of the use of this system in MRI, but current literature is unclear as to the clinical use of the Goutallier classification. There will be significant inter- and ...

Background: Conventional fat quantification methods for rotator cuff muscles have various limitations, such as inconsistent reliabilities of the Goutallier grades and need for advanced techniques in quantitative MRI sequences. We aimed to examine a threshold-based fat quantification method in the ...
We determined the correlation and reliability of two methods, the Lava Flex and Ideal IQ MRI techniques, in quantifying volumetric intramuscular fat, while also comparing to the Goutallier method. Materials and methods: The supraspinatus muscles of seventeen cadaveric shoulders were...
MRIDixonQuantification of rotator cuff intramuscular fatty infiltration is important for clinical decision-making in patients with rotator cuff tear. The semi-quantitative Goutallier classification system is the most commonly used method, but has limited reliability. Therefore, we sought to test a freely...
