“…18 Since that time, over 100 patients with MRI of suspected or confirmed spinal cord infarction have been described. [18][19][20][21][22][23][24] Though MRI has been available for some time in veterinary medicine, and spinal cord infarction has been a recognized pathology since 1973, 5 there have been no reports published in the veterinary literature regarding the MR appearance of suspected spinal cord infarction in dogs.…”

“…MR imaging (MRI) in human spinal cord infarction is most commonly characterized by a hyperintensity within the gray matter of the spinal cord on T2‐weighted images. Contrast enhancement on T1‐weighted images is commonly seen, developing most clearly 1 week after an acute infarct, and usually resolving within a month's time 18–24 . A literature search failed to produce any publication describing MRI of suspected infarcts in veterinary patients.…”

Ischemia and infarction of the spinal cord is a known cause of acute spinal injury in dogs. Currently, the diagnosis of spinal cord infarction in small animals is based on history, clinical signs, and the exclusion of other differentials with radiography and myelography. It is a diagnosis only confirmed through necropsy examination of the spinal cord. The aim of this paper is to describe the Magnetic resonance imaging (MRI) findings of the spinal cord of dogs with suspected spinal cord infarcts to utilize this technology for antemortem support of this diagnosis. This retrospective study evaluated the spinal MR examinations of 11 dogs with acute onset of asymmetric nonpainful myelopathies. All patients except one (imaged at 2 months) were imaged within 1 week of clinical signs and managed conservatively with minimal medical and no surgical intervention. They were followed clinically for a minimum of 4 months after discharge. MR findings in all dogs were characterized by focal, intramedullary, hyperintense lesions on T2-weighted images with variable contrast enhancement similar to what is reported in humans. Though it could not be used to diagnose spinal cord infarction definitively, MRI was useful in excluding extramedullary spinal lesions and supporting intramedullary infarction as a cause of the acute neurologic signs. Together with the history and clinical examination findings, MRI is supportive of a diagnosis of spinal cord infarction.

The increasing availability of magnetic resonance imaging (MRI) and the high sensitivity of MRI for soft tissue injury are resulting in the increased use of MRI for the evaluation of acute trauma. As cervical spine injury can have a devastating consequence, MRI is being more commonly used to evaluate cervical spine injury in the acute setting, necessitating emergent interpretation by the on-call radiologist. Unless one is formally trained in a trauma center, the MRI findings of soft tissue and ligamentous cervical spine injury may not be fully appreciated. The goal of this pictorial review is to familiarize the reader with some of the more common soft tissue, vascular, and ligamentous injuries seen on MRI of the cervical spine in the emergent setting.

“…MRI is widely considered to be the study of choice when paralysis is incomplete, or under other circumstances in which direct visualization of neural or ligamentous structures is clinically necessary. If surgery for herniated disc, hematoma, or other cause of incomplete paralysis is planned, MRI best depicts the relationship of pathology to the cord, and can help predict which patients may benefit from surgery [20][21][22][23][24][25][26] (Variant 1).…”
