The purpose of this study was to determine the relative merits of MR imaging and three-compartment digital arthrography in the assessment of carpal ligaments in vitro. We performed MR imaging and arthrography in 10 normal wrists of fresh cadavers ranging in age from 48 to 71 years, and compared the appearance of the interosseous ligaments and triangular fibrocartilage complex with findings on anatomic sections of the joints. In six of the specimens, relatively T1-weighted MR images, 800/20 (TR/TE), preceded three-compartment digital arthrography performed with standard contrast material. In the other four specimens, arthrography, using an MR solution of iodinated contrast material mixed with cupric sulfate and gelatin, was performed before MR imaging. This was done to mimic the intraarticular fluid that might be seen in an injured wrist. MR allowed accurate assessment of the triangular fibrocartilage complex and scapholunate ligament in eight of 10 cases. Consistent MR visualization of the lunotriquetral ligament was difficult. Three-compartment digital arthrography allowed accurate assessment of the triangular fibrocartilage complex and scapholunate and lunotriquetral ligaments in all 10 cases. We concluded that MR is useful but inferior to arthrography in the evaluation of interosseous ligaments and the triangular fibrocartilage complex.
本研究的目的是确定磁共振成像（MR成像）和三室数字关节造影在体外评估腕关节韧带方面的相对优点。我们对10具年龄在48至71岁之间的新鲜尸体的正常腕关节进行了MR成像和关节造影，并将骨间韧带和三角纤维软骨复合体的表现与关节解剖切片的结果进行了比较。在6个标本中，先进行相对T1加权的MR图像（800/20，TR/TE），然后用标准造影剂进行三室数字关节造影。在其他4个标本中，在MR成像之前进行关节造影，使用的是与硫酸铜和明胶混合的碘化造影剂的MR溶液。这样做是为了模拟受伤腕关节中可能出现的关节内液体。MR在10例中的8例中能够准确评估三角纤维软骨复合体和舟月韧带。月三角韧带的MR持续显影困难。三室数字关节造影在所有10例中都能准确评估三角纤维软骨复合体以及舟月韧带和月三角韧带。我们得出结论，在评估骨间韧带和三角纤维软骨复合体方面，MR是有用的，但不如关节造影。
