To evaluate the diagnostic capabilities of magnetic resonance (MR) imaging in the tarsometatarsal ([TMT] Lisfranc) joint with close anatomic correlation.
Six normal cadaveric feet were imaged by using T1-weighted spin-echo (oblique axial) and three-dimensional spoiled gradient-recalled acquisition in the steady state ([SPGR] coronal, sagittal) sequences. Subsequently, gadolinium-enhanced arthrography was performed in three specimens followed by T1-weighted spin-echo and SPGR MR imaging. Specimens were sectioned in all three planes followed by correlation of the MR imaging results with gross anatomic findings.
In all specimens, the oblique axial and, less effectively, the coronal and sagittal planes allowed visualization of the Lisfranc ligament. Intermetatarsal ligaments were seen almost exclusively on the coronal images, and TMT ligaments on the sagittal images. Bone alignment could be assessed on the oblique axial images.
MR imaging reliably depicts the anatomy of the TMT joint including ligamentous and osseous structures.
通过紧密的解剖关联来评估磁共振（MR）成像在跗跖（[TMT] Lisfranc）关节的诊断能力。
使用T1加权自旋回波（斜轴位）和三维扰相梯度回波稳态采集（[SPGR]冠状位、矢状位）序列对六只正常尸体足进行成像。随后，对三个标本进行钆增强关节造影，接着进行T1加权自旋回波和SPGR MR成像。在所有三个平面上对标本进行切片，然后将MR成像结果与大体解剖学发现进行关联。
在所有标本中，斜轴位以及效果稍差的冠状位和矢状位平面都能显示Lisfranc韧带。跖骨间韧带几乎仅在冠状位图像上可见，而TMT韧带在矢状位图像上可见。骨对线情况可在斜轴位图像上进行评估。
MR成像能够可靠地描绘TMT关节的解剖结构，包括韧带和骨骼结构。
