Factors predictive of abnormal results for computed tomography of the head in horses affected by neurologic disorders: 57 cases (2001–2007)

Abstract

These results suggested that alterations in consciousness and cranial nerve deficits were strong predictors of abnormal CT findings for the head of affected horses. Thus, CT can be a useful complementary diagnostic test in horses with these neurologic deficits. In contrast, alternative diagnostic tests (eg, electroencephalography and magnetic resonance imaging) should be considered in horses with seizure-like activity that do not have head trauma or cranial nerve deficits.

Diagnosis of severe traumatic brain injury using multimodal imaging in a donkey

“…In a previous study, which examined horses with seizures, CT was unable to detect intracranial lesions (Sogaro‐Robinson et al . ). Thus MRI is more sensitive than CT for the visualisation of soft tissue abnormalities in the brain (Sogaro‐Robinson et al .…”

Acquired epilepsy in a horse associated with colic surgery

“…As the aetiology could not be determined more precisely and considering the interictal signs of amaurosis present, due to a forebrain lesion most likely acquired, the authors assumed a case of acquired epilepsy. In horses, MRI is more sensitive for detecting cranial disorders associated with seizures than CT (Sogaro and others 2009, Lacombe and others 2010) and could have given interesting information about the intracranial lesion, even though in another study on seizures in horses only 2 out of 31 cases had detectable abnormalities in MRI of the head (Manso-Díaz and others 2014). MRI or CT have not been performed in this case because of limited availability.…”

Diagnosestellung bei einem Fohlen mit zerebellärer Abiotrophie mittels Magnetresonanztomographie (MRT)

“…MRI evaluation of the equine head is a feasible and valuable neurodiagnostic modality for the assessment of equine neurologic disease (Ferrell et al 2002). As compared to computed tomography (CT) (Sogaro-Robinson et al 2009), MRI provides high anatomic detail and exceptional soft tissue contrast of the central nervous system (CNS). Therefore MRI has an enormous potential in the assessment of suspected brain and spinal cord disorders in the horse.…”
