Notice to Candidates: We would
like to inform you that the fellowship position
has been filled for the 2012-2013 year. Drs.
Whitcomb & Vaughan
would like to express our appreciation to all
applicants for their interest in our program. Our
next recruitment period will begin in the Fall
of 2012.
The goals of the fellowship are to produce veterinarians with advanced technical and interpretative skills in this important clinical discipline. The species emphasis is equine but fellows will gain exposure to other large animal species. This position is an 80% clinical appointment with 20% time for off clinic pursuits (see below). Annual salary is $27,756 with medical benefits included. Housing is not provided. The fellowship begins August 1, 2012 and ends July 31, 2013. This webpage is designed to provide potential applicants with detailed information regarding our program, including overall service information, faculty and previous fellow information, case numbers, case distribution and application information. Please check the box at right for important announcements regarding the application process.
UC Davis Large Animal Ultrasound Service

The Large Animal Ultrasound Service provides diagnostic imaging services 5 days per week. The majority of the service caseload is supported by the equine surgery service, therefore, a large percentage of ultrasound exams are musculoskeletal in nature; however, a wide variety of ultrasound exams are performed. The intern will receive training in sonographic evaluation of all areas, including the abdomen, thorax, cardiac, ophthalmologic and high speed treadmill evaluations of poor performance racehorses. The equine caseload consists of a variety of performance horses, including dressage, hunter/jumpers, endurance horses, western performance horses (cutting, reining, roping, barrel racing), pleasure horses and specialty breeds such as Peruvian Pasos. A working knowledge of performance horses is beneficial. There is little to no emergency duty. Emergency colic ultrasound evaluations are performed by the surgery resident on call. The large animal medicine service performs medical emergency ultrasound evaluations.

The UCD Large Animal Ultrasound Service has a full range of equipment available for all aspects of equine, food animal and small ruminant ultrasound. We are fortunate to have two Biosound Technos ultrasound systems that allow us to evaluate 2 patients simultaneously with machines that excel at musculoskeletal and abdominal imaging. Transducers available include two 8-14 MHz linear transducers and a 5-10 MHz linear transducer for musculoskeletal use, a 4-8 MHz microconvex transducer for neonatal and small ruminant abdominal/thoracic imaging and two 2-5 MHz curvilinear transducers for adult equine abdominal and thoracic imaging. We continue to use the GE Vingmed System 5 ultrasound system, primarily for cardiac imaging for its unbeatable color Doppler imaging and excellent depth of penetration (30cm). The Vingmed also produces high quality musculoskeletal and abdominal images. Transducers available for this machine include a 2.5 MHz phased array transducer for cardiac imaging, 3.5 MHz and 5.0 MHz curvilinear transducers for abdominal imaging and a 10 MHz linear transducer for musculoskeletal and small parts imaging. Finally, we have retained an Ausonics Impact ultrasound system in our arsenal for teaching purposes and its unique ability to penetrate to 40cm of depth. We have 2.5 MHz and 3.5 MHz sector transducers, a 6.0 MHz rectal transducer and a 7.5 MHz linear transducer for the Impact.

Acoustic Shock Wave Therapy
Acoustic shock wave treatments are also performed by the large animal ultrasound service. Shock wave therapy is thought to stimulate healing and potentially reduce layup time in horses with musculoskeletal injuries such as stress fractures, bucked shins, suspensory ligament desmitis and distal sesamoidean ligament desmitis. Treatments are generally performed by the ultrasound fellow. We are currently using the Duolith Vet shock wave machine manufactured by Storz Medical. The Duolith has both focused and nonfocused capabilities. Focused shock wave is most commonly used to treat musculoskeletal injuries. Nonfocused shock wave has been used to break up cystoliths (bladder stones) to facilitate their removal during surgery.
Fellow Clinical Responsibilities
Perform and interpret ultrasound examinations on patients presenting to the Large Animal Ultrasound Service under the direction of faculty from the Department of Surgical and Radiological Sciences.
