Multishot diffusion-weighted imaging features in spinal cord infarction.
The purpose of this study was to use a multishot, navigator-corrected, echo-planar (EP) pulse sequence to perform clinical diffusion-weighted imaging (DWI), analyze the DWI findings in ischemic spinal cord lesions, and discuss the value of DW magnetic resonance imaging (MRI) in distinguishing infarction (especially in the subacute stage) from inflammatory diseases and tumors of the spinal cord. ⋯ MRI is useful in detecting spinal cord infarction. DWI (especially multishot DWI) of the spinal cord may provide additional information for the assessment of ischemic changes and help improve in differentiating diagnosis.

The thoracolumbar injury severity score: a proposed treatment algorithm.
Significant controversy exists regarding the optimal management of thoracolumbar injuries. This is in part due to the lack of understanding of the natural history of various injury subtypes and the absence of a universally accepted classification scheme that facilitates communication among care providers and assists in directing treatment. The Spine Trauma Study Group has developed an injury severity score based on three major variables: the mechanism of injury determined by radiographic appearance, the integrity of the posterior ligamentous complex, and the neurologic status of the patient. By systematically assigning specific point values within each category based on the severity of injury, a final severity score may be generated that can be used to help direct treatment. The goal of this work is to present a proposal of a detailed treatment algorithm to assist in the nonoperative or operative management of thoracolumbar injuries. ⋯ The proposed treatment algorithm is an attempt to assist physicians using best-evidence medicine in managing thoracolumbar spinal injuries. The final point flow chart with graduated treatment recommendations is only preliminary and needs to be validated through prospective cohort analysis. In addition, the importance of the chosen variables determining spinal stability must also be verified.
