The imaging features considered positive for a possible syrinx-associated lesion on T2-weighted imaging were syrinx nodularity, syrinx septations, and a spinal cord signal intensity abnormality or a mass separate from the syrinx. Transverse myelitis, a.k.a. While spinal Cervical radiculopathy. 1 The most common location is the cervical region, and only about 6.5% involves the distal spinal cord or the conus medullaris. Core tip: Advancements in diagnostic imaging over the last few decades have developed spinal imaging from simple subjective and qualitative indices into a more sophisticated yet precise era of objective metrics via deploying quantitative imaging biomarkers. compression). The small spinal cord volume and relatively increased respiratory and cardiac motion in the pediatric population can make high-quality imaging of the spinal cord challenging. It helps diagnose or rule out acute spinal cord compression when a physical exam shows muscle weakness or paralysis. Unlike X-rays or computed tomography (CT scans), MRI does not use ionizing radiation. International Journal of Contemporary Medicine Surgery and Radiology. 43.

MRI. Mri Brain. Cervical cord compression and trauma. Introduction: Traumatic injuries of the spine and spinal cord are potentially devastating as they may lead to significant neurological damage as the clinical and prognostic spectrum of the effects of spinal injuries is vast. The emergency department radiologist should be familiar with the common differential diagnoses of acute myelopathy and be able to differentiate compressive from noncompressive causes. The overall goal of her ongoing study is to establish resting state functional magnetic resonance imaging (rs-fMRI) of the brain as a clinical tool to evaluate the extent .

Basically we rely on the sagittal T1W- and T2W-images and correlate the findings with the transverse T2W-images of the levels of suspected pathology. The presence or absence of an associated spinal cord mass was determined using only T2-weighted imaging. Long spinal cord lesions extending > 3 vertebral segments were classified as LESCLs (Figure 1) while any lesion falling short of 3 vertebral segments was termed scattered spinal cord lesions (sSCLs; Figure 2).
