Cellulite is characterized by alterations in the relief of the skin surface. Magnetic resonance imaging (MRI) is recognized as a reliable technique for measuring adipose volume according to body site and for the visualization of the subcutaneous structures.
To compare subcutaneous tissue in areas with and without cellulite on the buttocks of same subjects using a noninvasive technique.
Thirty female patients with cellulite on the buttocks underwent MRI. An area with cellulite and another without cellulite on the contralateral buttock were selected. Two soft gelatin capsules of different sizes were used as skin markers to differentiate the areas with and without cellulite.
Fibrous septa were visualized in 96.7% of the area with cellulite depressions; most of them were ramified (73.3%) and presented a high-intensity signal on T2 images (70%). All fibrous septa found in the examined areas were perpendicular to the skin surface. The average fibrous septa thickness was 2.18 +/- 0.89 in the area with cellulite and 0.27 +/- 0.64 in the area without cellulite.
Results of the MRI analysis showed that cellulite depressions on the buttocks were significantly associated with the presence of underlying fibrous septa.
橘皮组织的特征是皮肤表面纹理改变。磁共振成像（MRI）被认为是一种可靠的技术，可根据身体部位测量脂肪体积并可视化皮下结构。
使用无创技术比较同一受试者臀部有橘皮组织和无橘皮组织区域的皮下组织。
30名臀部有橘皮组织的女性患者接受了MRI检查。在对侧臀部选择一个有橘皮组织的区域和另一个无橘皮组织的区域。使用两颗不同大小的软明胶胶囊作为皮肤标记物，以区分有橘皮组织和无橘皮组织的区域。
在96.7%有橘皮组织凹陷的区域中可见纤维间隔；其中大多数呈分支状（73.3%），在T2图像上呈现高强度信号（70%）。在检查区域发现的所有纤维间隔均垂直于皮肤表面。有橘皮组织区域的纤维间隔平均厚度为2.18±0.89，无橘皮组织区域为0.27±0.64。
MRI分析结果表明，臀部的橘皮组织凹陷与深层纤维间隔的存在显著相关。
