Ultrasound-guided caudal cervical articular process arthrocentesis is accurate in live horses with and without arthropathy.

Background: Cervical articular process joint (CAPJ) therapy is advocated for horses with neck disorders. Several ultrasound-guided CAPJ techniques have been described in cadaver studies with 72%-89% intra-articular injection accuracy; however, the CAPJ injection accuracy in clinical equine practice has not been extensively reported.

Objectives: To describe a modified cranial approach for ultrasound-guided caudal CAPJ injections, to investigate the accuracy of this CAPJ injection technique in live horses, and to assess the effect of CAPJ injection location, laterality, operator, and radiographic CAPJ enlargement on injection accuracy.

Computed tomographic diagnosis of a common bile duct abscess and secondary extrahepatic biliary duct obstruction in a potbelly pig.

A potbelly pig was evaluated for anorexia and icterus. Clinicopathologic abnormalities suggested an active inflammatory hepatobiliary process. Ultrasound and CT of the abdomen revealed an extrahepatic biliary obstruction of the common bile duct (CBD).

Incidence and risk factors for complications associated with equine general anaesthesia for elective magnetic resonance imaging.

Background: Complications are a practical consideration for elective magnetic resonance imaging (MRI) studies performed under general anaesthesia but relatively little is known about their distribution and risk factors.

Objectives: To describe the incidence of complications associated with MRI performed under general anaesthesia at a large referral facility and evaluate potential risk factors for these complications.

Study Design: Retrospective case-control study.

Avascular necrosis of the femoral head in a cynomolgus macaque (Macaca fascicularis).

A cynomolgus macaque presented with right hindlimb lameness as well as crepitus and decreased passive range of motion of the right coxal joint. Radiography and histopathology were consistent with avascular necrosis of the femoral head. This case is the first published report of this condition in a cynomolgus macaque.

Identification of a previously unreported site of subchondral bone injury in the dorsodistolateral calcaneus in Thoroughbred racehorses.

Background: Increasing accessibility and advancements in computed tomographic (CT) imaging improve understanding of the contributors to poor performance in the Thoroughbred racehorse.

Objectives: To characterise an unreported site of tarsal subchondral bone injury (SBI) in Thoroughbred racehorses.

Study Design: Retrospective, cross-sectional analytical study.

Small Animal Teleultrasound.

Teleradiology is well established in many small animal practices, whereas teleultrasound is slowly gaining prominence. The demand for teleultrasound services in the veterinary profession has increased substantially because access to ultrasound to general practitioners increases faster than the number of imaging specialists and Point of Care Ultrasound (POCUS) becomes part of the standard of care. Two main methods of teleultrasound currently exist: asynchronous (eg, "store-and-forward") and synchronous (eg, real-time) interpretations.

Utility of radiographic measurements to predict echocardiographic left heart enlargement in dogs with preclinical myxomatous mitral valve disease.

Background: Evaluation of left heart size helps determine disease severity in dogs with myxomatous mitral valve disease (MMVD).

Hypothesis/objectives: Determine the ability of radiographic vertebral heart size (VHS) and vertebral left atrial size (VLAS) to predict LHE in dogs with preclinical MMVD.

Animals: Seventy client-owned dogs with MMVD and no historical or present clinical or radiographic evidence of congestive heart failure (CHF).
