Canine Bone Scan
This modality is a great resource for diagnosing obscure lameness issues in our canine friends. The patient is injected with a radioisotope, which is then allowed 2 hours to distribute throughout the body. The bone scan is then performed under sedation (rather than general anesthesia). At Animal Imaging, if combined modalities are needed to further assess the lameness, such as radiographs, CT, or ultrasound, we are able to do that in the same visit. Patients are checked in for the day at 7:30am the morning of the appointment, and we will call as soon as they are ready to go (usually early afternoon.) Results are ready within 24 hours and sent to the referring veterinarian, as well as the owner.
Trans-splenic Portal Scan
Portosystemic shunts are anomalous vessels which allow portal blood to bypass the liver and enter the systemic circulation.
A diagnosis of portosystemic shunting is often achieved at Animal Imaging with trans-splenic portal scintigraphy where a nuclear portogram is acquired. A small dose of radionuclide is administered under ultrasound guidance into the spleen. The passage of radionuclide is dynamically evaluated to determine if a macroscopic portosystemic shunt is present and if the pattern of uptake supports a single congenital shunt or multiple acquired shunts. This procedure is complemented with an abdominal ultrasound to further evaluate the intra-abdominal organs and further characterize the shunting vessel(s) if present.
Computed tomography (CT) exams are extremely useful in diagnosing portosystemic shunts and are also utilized to assess portal-vascular anatomy. Non-ionic iodinated contrast agents are used in CT exams to define abdominal vasculature.
Our veterinary Radiologists have completed an approved Residency Program in Diagnostic Imaging that includes at least three years of advanced training and intensive study in Radiology (x-ray), Ultrasonography, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Nuclear Medicine. The radiologists at Animal Imaging include Dr. Rita Echandi, Dr. Dana Neelis, and Dr. Beth Biscoe.
Thyroid Scan and Radioactive Iodine (I-131)
The Thyroid Scan is the first of a two-step process when a feline patient is being considered for Radioactive Iodine Treatment (I-131). This first appointment is about one to one and a half hours long, and it helps us determine, from a nuclear medicine standpoint, that the patient is a good candidate for treatment. We also use this appointment to discuss all risks, instructions, and concerns for the treatment, should we move forward.
When scheduling treatment, there are significant after care instructions to be considered.
