Intramedullary cord hyperintensity at T2-weighted MRI is a common imaging feature of disease in the spinal cord, but it is nonspecific. Radiologists play a valuable role in helping narrow the differential diagnosis by integrating patient history and laboratory test results with key imaging characteristics. The authors present an algorithmic approach to evaluating intrinsic abnormality of spinal cord signal intensity (SI), which incorporates clinical evaluation results, time of onset (acute vs nonacute), cord expansion, and pattern of T2 SI abnormality. This diagnostic approach provides a practical framework to aid both trainees and practicing radiologists in workup of myelopathy.RSNA, 2019.
脊髓 T2 加权 MRI 中的髓内脊髓高信号是脊髓疾病的常见影像学特征,但不具有特异性。放射科医生通过将患者病史和实验室检查结果与关键影像学特征相结合,在帮助缩小鉴别诊断范围方面发挥了重要作用。作者提出了一种评估脊髓信号强度(SI)内在异常的算法方法,该方法结合了临床评估结果、发病时间(急性与非急性)、脊髓扩张和 T2 SI 异常模式。这种诊断方法为培训医师和执业放射科医生提供了一个实用的框架,以帮助他们对脊髓病进行检查。RSNA,2019 年。
