Computed tomography, ultrasonography, and magnetic resonance imaging are useful in the diagnosis of tears of the Achilles tendon, but none are capable of detecting early or small tears. Herein, we applied diffraction-enhanced imaging, a radiographic technique that detects x-ray attenuation and x-ray refraction, to the imaging of compromised Achilles tendons.
Diffraction-enhanced imaging was used to detect incomplete surgically induced tears of the Achilles tendon in nine cadaveric human feet and ankles.
Complete and significant partial tears were detectable in diffraction-enhanced images as x-ray refraction changes.
Although still in the experimental stages, diffraction-enhanced imaging may eventually prove useful for the diagnosis of Achilles tendon tears.
计算机断层扫描、超声检查和磁共振成像在跟腱撕裂的诊断中很有用，但都无法检测早期或小的撕裂。在此，我们将衍射增强成像（一种检测X线衰减和X线折射的放射技术）应用于受损跟腱的成像。
衍射增强成像用于检测9例人尸体足和踝关节手术诱发的跟腱不完全撕裂。
在衍射增强图像中，完全撕裂和明显的部分撕裂可作为X线折射变化被检测到。
尽管仍处于实验阶段，但衍射增强成像最终可能被证明对跟腱撕裂的诊断有用。
