Ex vivo diffusion tensor imaging of the plantar nerves is feasible in the horse.

Objective: The objective of this study was to optimize an MRI-based diffusion tensor imaging (DTI) protocol for imaging the plantar nerves at the level of the tarsus in normal equine limbs.

Sample: 12 pelvic cadaver limbs from horses without evidence of proximal suspensory pathology were imaged with a 3T MRI system.

Methods: For diffusion-weighted imaging, b values of 600, 800, and 1,000 s/mm2 were tested.

Imaging diagnosis: Disseminated hemangiosarcoma in a Welsh pony.

A 16-year-old pony gelding presented with epistaxis and a head tilt. Referral skull radiographs suggested an ethmoid hematoma. Concurrent neurologic abnormalities prompted contrast-enhanced CT of the head and cranial neck, revealing numerous hyperattenuating masses throughout the brain and paranasal sinuses, along with a large osteolytic mass in the second cervical vertebra.

Gastrointestinal release site for delayed release and gelatin capsules in healthy dogs.

Gelatin capsules deliver their contents to the stomach, while delayed-release (DR) capsules are designed to allow delivery to the small intestine. This study evaluated the gastrointestinal release site of DR capsules in six healthy adult dogs compared to gelatin capsules. Both gelatin and DR capsules were filled with barium-impregnated polyethylene spheres (BIPS™), and following enteral administration, release site was assessed using abdominal radiographs at baseline, immediately after ingestion, 15 min post-ingestion, 30 min post-ingestion, and then every 30 min thereafter.

Temporal tracheobronchial lymphadenopathy resolution is affected by initial severity and poorly correlated to serologic antibody testing in dogs with pulmonary coccidioidomycosis.

Objective: To determine associations between antibody serologic tests and tracheobronchial lymphadenopathy (TBL) in dogs with pulmonary coccidioidomycosis and identify variables associated with time to resolution of TBL.

Animals: 32 client owned dogs with newly diagnosed pulmonary coccidioidomycosis from October 2020 to February 2021.

Methods: Prospective cohort study.

Preliminary study evaluating the assessment of changes in pulmonary function associated with body positioning in dogs with suspected aspiration pneumonia.

Objective: To evaluate the variability in arterial blood gas (ABG) assessment of pulmonary function with different body positioning in dogs with suspected aspiration pneumonia.

Key Findings: The median differences in alveolar-arterial gradient, Pao , and Paco values in different recumbencies were not statistically significantly different, both within patients and across the study population. No difference was noted in ABG values in the subgroups with unilateral or bilateral disease or that were more affected on the right side versus the left side.
