MR images of the fingers are obtained in a 128 x 128 or 256 x 256 matrix format using a prototype of a mini imager dedicated to the hand. The vertical field of 0.1 T is provided by an electro-magnet with an air gap of 15 cm equipped with a single solenoidal coil. No Faraday cage is used. The maximum in plane pixel resolution of 100 mu is obtained for a field of view of 2.5 cm with a slice thickness of 2 mm. The identification of fine structures of the finger is demonstrated by the anatomical and histological correlations. This type of imager which is adapted to very limited field of views demonstrate that high resolution MRI of limb extremities can be achieved at 0.1 T.
手指的磁共振成像（MR）图像是使用一款专门用于手部的微型成像仪原型，以128×128或256×256矩阵格式获取的。0.1特斯拉的垂直磁场由一个气隙为15厘米的电磁铁提供，该电磁铁配备有一个单螺线管线圈。未使用法拉第笼。对于2.5厘米的视野和2毫米的切片厚度，可获得100微米的最大平面像素分辨率。手指精细结构的识别通过解剖学和组织学相关性得以证明。这种适用于非常有限视野的成像仪表明，在0.1特斯拉的磁场强度下可以实现四肢的高分辨率磁共振成像。
