手指的伸展是一种复杂的功能，通过外在和内在肌肉的同时动作以及腕、手和手指的背侧中的支持带结构来执行，所述支持带结构支持和协调肌肉的动作。手指的伸肌机制被分成从前臂延伸到远节指骨的地形区。磁共振（MR）成像显示详细的肌肉肌腱和支持带结构的伸肌装置。在不同的伸肌区，MR成像所见与解剖切片中肉眼所见相似。了解和熟悉伸肌的解剖结构。手和手指的放射科医生是至关重要的病理条件与磁共振成像和优化这种模式作为一种诊断工具的评估。伸肌腱损伤和腱鞘炎代表了临床情况，在这种情况下，解剖学知识对临床放射科医生是有用的。（（C））RSNA，2003年。
Extension of the fingers is a complex function carried out by simultaneous action of extrinsic and intrinsic muscles, as well as retinacular structures in the dorsum of the wrist, hand, and fingers that support and coordinate the action of the muscles. The extensor mechanism of the fingers is divided into topographic zones, which extend from the forearm to the distal phalanx. Magnetic resonance (MR) imaging shows in detail the musculotendinous and retinacular structures of the extensor apparatus. In the different extensor zones, MR imaging findings are similar to those seen macroscopically in anatomic sections. Understanding of and familiarity with the extensor anatomy of the. hand and fingers by the radiologist is crucial for better assessment of pathologic conditions with MR imaging and optimization of this modality as a diagnostic tool. Extensor tendon injuries and tenosynovitis represent clinical situations in which knowledge of this anatomy is useful for the clinical radiologist. ((C))RSNA, 2003.
