[Tips, tricks and pitfalls in the diagnostic imaging of traumatic spinal cord injuries].
Over the last several decades the survival rate for acute spinal cord lesions has improved, which has resulted in an increased number of chronic spinal cord injuries. Magnetic resonance imaging (MRI) plays an essential role in imaging of the spinal cord, as it allows a detailed depiction of neural structures. However, the correct radiologic diagnosis is often complicated by the multitude of differential diagnoses. This article provides tips and tricks to achieve an accurate imaging report and details potential pitfalls in the interpretation of MR images. Acute spinal cord injuries show different characteristics which range from edema to intramedullary bleeding and to transsection. The spectrum of chronic spinal cord injuries encompasses myelomalacia, syrinx, cystic myelopathia and myeloatrophy. In addition to typical morphological features this article concentrates on the pathogenesis of injury patterns, on the use of appropriate contrast-enhanced MR sequences and on new MR techniques for the differentiation of individual pathologies.
