A chondroblastic osteosarcoma of the coronoid process mimicking a fragmented coronoid process in a dog.

A 6-year-old Rhodesian Ridgeback was presented with a 1.5 year history of right forelimb lameness. Clinical, radiological and computed tomographic findings suggested the presence of fragmented medial coronoid process.

Computed Tomographic and Low-Field Magnetic Resonance Arthrography: A Comparison of Techniques For Observing Intra-articular Structures of the Normal Canine Shoulder.

Objective: To compare low-field magnetic resonance arthrography (MRA) and computed tomographic arthrography (CTA) for identification of intra-articular ligaments and joint cartilage in the normal canine shoulder with the aid of cross-sectional anatomy.

Animals: Normal adult Foxhounds (n = 3) and 4 Foxhound cadaver shoulders.

Methods: CTA of 3 dogs was performed after intra-articular administration of contrast medium in both shoulders.

Micro-computed tomography of the head and dentition in cadavers of clinically normal rabbits.

Objective: To describe the anatomic features of dentition and surrounding structures of the head in rabbits assessed by use of a newly developed micro-computed tomography (CT) device.

Sample: Cadavers of 7 clinically normal adult Dendermonde White domestic rabbits raised for human consumption.

Procedures: The rabbits were slaughtered in a slaughterhouse, flayed, and decapitated; the rabbit heads were frozen for micro-CT examination.

Low-field magnetic resonance imaging and cross-sectional anatomy of the rabbit head.

The purpose of this study was to provide a detailed anatomical description of the soft-tissue structures of the head of normal rabbits using low-field magnetic resonance imaging (MRI). The cadaver heads of six domestic rabbits and one dwarf rabbit were used to perform transverse, sagittal and dorsal 2.5-mm-thick T1-weighted images.

Computed tomography and cross-sectional anatomy of the head in healthy rabbits.

Objective: To obtain a detailed anatomic description of the rabbit head by means of computed tomography (CT).

Animals: 6 clinically normal Dendermonde White rabbits weighing 3 kg and raised for human consumption and 1 Netherland dwarf rabbit.

Procedures: The commercially raised rabbits were slaughtered in a slaughterhouse, flayed, and decapitated.

Computed tomography and cross-sectional anatomy of the brain in clinically normal dogs.

Objective: To provide a detailed anatomic description of brain structures in clinically normal dogs by means of computed tomography (CT).

Animals: 4 clinically normal adult German Shepherd Dogs weighing 30 to 35 kg.

Procedure: Each dog was anesthetized and positioned in ventral recumbency for CT examination of the brain; transverse scans were completed at 2-mm intervals from the cribriform plate of the ethmoid bone to the cranial part of the atlas by use of a third-generation CT scanner.

Computed tomography and cross-sectional anatomy of the thorax in clinically normal dogs.

Objective: To provide a detailed anatomic description of the thorax in clinically normal dogs by means of computed tomography.

Animals: 4 clinically normal adult German Shepherd Dogs weighing 28 to 37 kg.

Procedure: Dogs were anesthetized and positioned in ventral recumbency for computed tomographic (CT) examination of the thorax.

Magnetic resonance imaging, computed tomography, and cross-sectional views of the anatomy of normal nasal cavities and paranasal sinuses in mesaticephalic dogs.

Objective: To use computed tomography (CT) and magnetic resonance imaging (MRI) to provide a detailed description of the nasal cavities and paranasal sinuses in clinically normal mesaticephalic dogs.

Animals: 2 clinically normal Belgian Shepherd Dogs that weighed 25 and 35 kg, respectively.

Procedure: The first dog was anesthetized and positioned in ventral recumbency for CT and MRI examinations, and transverse slices were obtained from the caudal part of the frontal sinuses to the nares.

Computed tomography of the elbow joint in clinically normal dogs.

Objective: To use computed tomography (CT) to provide a detailed description of elbow joint structures in clinically normal dogs.

Animals: 6 clinically normal adult mixed-breed dogs weighing 24 to 37 kg and one 12-month-old Labrador Retriever weighing 27 kg.

Procedure: To perform CT of both elbow regions, dogs were anesthetized and placed in lateral recumbency.
