Magnetic resonance imaging was applied to eight cadaver wrists to evaluate the efficacy of imaging the anterior radiocarpal ligaments. In order to verify a correlation between the magnetic resonance images and anatomic structures, ancillary studies using gadolinium-DTPA ligamentography and gross sectioning of the specimens were performed. The ligaments targeted for evaluation were the radioscaphocapitate, long radiolunate, and short radiolunate ligaments. The highest resolution images were obtained using a 1.5 Tesla magnetic resonance imaging scanner and a surface coil applied to the wrist region, and producing T1-weighted images, with 3 mm thick sections with an 8 cm field of view. The radioscaphocapitate, long radiolunate, and short radiolunate ligaments were most consistently identified in sagittal planes, however they were also identified in coronal planes. The radioscapholunate ligament and the interosseous ligaments between the scaphoid, lunate, and triquetrum were most consistently identified in coronal planes. Transaxial planes provided consistently inferior views, and should be reserved for imaging of the flexor and extensor retinaculae.
对8具尸体手腕进行磁共振成像，以评估腕掌侧韧带成像的效果。为了验证磁共振图像与解剖结构之间的相关性，进行了使用钆喷酸葡胺韧带造影和标本大体切片的辅助研究。评估的韧带为桡舟头韧带、桡月长韧带和桡月短韧带。使用1.5特斯拉磁共振成像扫描仪和应用于腕部区域的表面线圈获得最高分辨率图像，生成T1加权图像，层厚3毫米，视野8厘米。桡舟头韧带、桡月长韧带和桡月短韧带在矢状面最易识别，但在冠状面也可识别。桡舟月韧带以及舟骨、月骨和三角骨之间的骨间韧带在冠状面最易识别。横断面提供的图像始终较差，应留作屈肌支持带和伸肌支持带的成像。
