Magnetic resonance imaging can visualize the soft tissue and the bone marrow of the hand. High spatial resolution requires the use of a surface coil. Signal-to-noise contrast was measured and compared for 3 different coils. Optimal results were obtained with a surface coil with a diameter of 8.5 cm. The wrist and the fingers of 10 volunteers each were examined. Images with a high spatial resolution and a good signal/noise contrast were obtained, enabling the delineation of small structures like Gynon's channel and the median nerve.
磁共振成像能够显示手部的软组织和骨髓。高空间分辨率需要使用表面线圈。对3种不同的线圈测量并比较了信噪比。使用直径为8.5厘米的表面线圈可获得最佳结果。对10名志愿者的手腕和手指分别进行了检查。获得了具有高空间分辨率和良好信号/噪声对比的图像，能够清晰显示诸如吉农管和正中神经等小结构。
