To See is to Know

There are many ways to go about obtaining a diagnosis. Knowing which modality to use in any given situation is the first challenge. Then having the ability to perform the imaging study or procedure, evaluate the results, and therefore make a recommendation on the best course of treatment is the yet another skill set. At AVIM, we are skilled at performing, administering and interpreting a variety of diagnostic technologies and treatment procedures, including:


Bronchoscopy is a procedure that allows your doctor to look at an animal’s airway through a thin viewing instrument called a bronchoscope. During a bronchoscopy, your doctor will examine the animal’s throat, larynx, trachea, and lower airways. Bronchoscopy may be done to diagnose problems with the airway, the lungs, or with the lymph nodes in the chest, or to treat problems such as an object or growth in the airway.


Colonoscopy is used to examine an animal’s large intestines (ileocecal valve, cecum, colon and rectum). Colonoscopy is often performed to evaluate patients with weight loss or diarrhea; it may also be used in concert with upper gastrointestinal endoscopy for more generalized signs of intestinal disease. Endoscopy can be used to diagnose inflammation, inflammatory bowel disease, ulcers, tumors, and fungal infections.


A cystoscope is used to examine the urethra and bladder. In a female animal, it is also used to examine the vaginal area. It is used to further evaluate patients with recurrent or persistent urinary tract infections; kidney, ureteral or bladder stones; urinary incontinence; or bladder masses.


An endoscopy involves examining the inside an animal’s body using an endoscope. An endoscope is a medical device consisting of a long, thin, flexible (or rigid) tube which has a light and a video camera. Images of the inside of the patient's body can be seen on a screen. The whole endoscopy is recorded so that doctors can check it again. Endoscopy is a minimally invasive diagnostic medical procedure. It is used to examine the interior surfaces of an organ or tissue. It can also be used for enabling biopsies and retrieving foreign objects.

Endoscopy is a noninvasive alternative to surgery for foreign object removal from the gastrointestinal tract.


Fluoroscopy is a technique used to study moving body structures, almost like an X-ray movie. An x-ray beam is continuously sent through the area to be viewed and then this image is sent to a monitor that can be viewed in “live” time. This technique is most often utilized with tracheal stent placement and swallow studies.


AVIM offers minimally invasive laparoscopic liver procedure with state of the art equipment.
Who can benefit from laparoscopic liver biopsy?
Medium to large sized dogs with liver disease caused by toxins, idiopathic chronic hepatitis, copper storage disease, infectious disease or neoplasia

Advantages of Laparoscopic Liver Biopsies

  • Optimal sampling with minimal healing time
  • Direct imaging of the entire liver, gallbladder, pancreas and spleen
  • Sample collection from multiple liver lobes
  • Larger sample size and quality allows for better evaluation of hepatic lobular architecture, distribution of inflammation, cell injury and fibrosis.
  • Improved hemostasis with compromised patients including those with ascites.
  • Improved Diagnostic Accuracy Improves Treatment Recommendations and Outcomes!


Rhinoscopy is used to examine an animal’s nasal cavity. It often includes two procedures: Anterior rhinoscopy and Posterior rhinoscopy. In anterior rhinoscopy, the rhinoscope is advanced through the nose to examine the nasal cavity. In posterior rhinoscopy, the rhinoscope is advanced through the mouth to examine the back of the nasal cavity above the soft palate. Rhinoscopy can be used to diagnose inflammation, foreign bodies, tumors, and fungal infections.
