“…Reports demonstrating the clinical utility of these technologies arise with increasing frequency in the veterinary literature. In cattle, CT was successfully used for diagnosis of neurological diseases, skeletal disorders, metastatic tumors, sinusitis, actinomycosis, bronchopneumonia, tympanosis, and morphological changes in the eyes and thyroid glands [ 11 , 25 – 30 ]. In horse, CT has proven to detect subchondral and occult osteochondral lesions [ 24 ] and to evaluate complex comminuted fractures when radiographic interpretation is difficult thanks to the cross-sectional images with spatial separation of the superimposed structures seen on survey radiographs.…”

Background Lameness in cattle is a major health problem and causes great economic losses. Carpal injury is a common cause of forelimb lameness in cattle. Radiography and/or ultrasonography of the carpus is a challenge due to complex anatomy of the joint. Additional imaging using computed tomography (CT) or magnetic resonance imaging (MRI) may be indispensable for reaching a decisive diagnosis. Precise evaluation of the clinical CT and MRI images necessitates an in-depth knowledge of the normal CT and MRI tissue variants. Therefore, our purpose was to provide a detailed description of the normal CT and MRI appearance of the osseous and soft tissue structures of twelve cadaveric bovine carpi using CT and 3 Tesla MRI. Carpi were frozen, transected in sagittal, dorsal and transverse planes then adjoined to their corresponding CT and MRI images. Results The clinically significant articular and peri-articular structures of the bovine carpus were identified and characterized on the CT and MRI images. CT images provided a remarkable delineation of the cortical, subchondral, and cancellous bone. The high-field 3 Tesla MRI offered high definition and distinction of the delicate soft tissues of the bovine carpus. Conclusions 3 Tesla high-field MRI offers new opportunities in soft tissue tomography but cannot be compared with CT in terms of bone imaging. Clinicians have to determine whether CT, MRI or both imaging techniques are required in clinical situations.

A 12‐day‐old, male Holstein Friesian calf was presented to the hospital due to progressive ataxia and tremors since birth. A diffuse central nervous system disorder primarily affecting white matter was suspected based on clinical neurological examination. Blood tests were unremarkable, except for positive serology for Schmallenberg virus. Magnetic resonance imaging of the brain demonstrated severe, diffuse abnormalities primarily affecting the white matter regions of the encephalon and cranial cervical spinal cord, consistent with leukoencephalomyelopathy. Euthanasia was performed at 8 weeks of age after no clinical improvement. A postmortem examination was performed. Histopathological examination of the central nervous system revealed changes compatible with hypomyelinating leukodystrophy, with no signs of infectious agents observed. The disorder was considered most likely to be hereditary, as Schmallenberg virus infections during pregnancy in cattle have not been reported to result in such clinical, magnetic resonance imaging or histopathological findings, and no viral genomic material was identified with polymerase chain reaction.
