On T1 and T2 weighted MR Imaging, normal Achilles tendon is generally described as a homogeneous low signal structure. However, punctuate and/or short linear high signal foci are often seen, especially on the anterior part of axial sections. These images are not artifacts. The aim of this study was to correlate MR images of 20 normal Achilles tendons with micro-anatomic and histologic studies of 2 cadaver tendons. Intratendinous vessels were found in connective tissue septa called mesotenon. Foci of high signals result from this mesotenon. On T1 weighted images, a normal Achilles tendon can present high signal images without any disease process.
在T1加权和T2加权磁共振成像上，正常跟腱通常被描述为均匀的低信号结构。然而，经常可以看到点状和/或短线性高信号灶，尤其是在轴位图像的前部。这些图像并非伪影。本研究的目的是将20条正常跟腱的磁共振图像与2条尸体肌腱的微观解剖和组织学研究进行对比。在称为腱系膜的结缔组织间隔中发现了腱内血管。高信号灶是由这种腱系膜导致的。在T1加权图像上，正常跟腱可呈现高信号图像而无任何疾病过程。
