Diffusion-weighted imaging and fractional anisotropy may be more sensitive than other conventional magnetic resonance imaging techniques to detect, characterize, and map the extent of spinal cord lesions. Fiber tracking offers the possibility of visualizing the integrity of white matter tracts surrounding some lesions, and this information may help in formulating a differential diagnosis and in planning biopsies or resection. Fractional anisotropy measurements may also play a role in predicting the outcome of patients who have spinal cord lesions. In this article, we address several conditions in which diffusion-weighted imaging and fiber tracking is known to be useful and speculate on others in which we believe these techniques will be useful in the near future.
扩散加权成像和分数各向异性在检测、表征和描绘脊髓病变范围方面可能比其他传统磁共振成像技术更敏感。纤维追踪能够可视化一些病变周围白质束的完整性，这些信息有助于进行鉴别诊断以及规划活检或切除术。分数各向异性测量在预测脊髓病变患者的预后方面也可能发挥作用。在本文中，我们阐述了几种已知扩散加权成像和纤维追踪有用的情况，并推测了我们认为这些技术在不久的将来会有用的其他情况。
