Veterinary Internal Medicine

All IndyVet specialists have received four or more years of post-doctorate training prior to board certification. This training and experience allows our specialists to manage and treat a wide variety of complex diseases and conditions in collaboration with general practitioner colleagues across the state of Indiana. This collaborative approach to case management allows us to provide the most versatile care for patients.

The goal of internal medicine at IndyVet is to provide compassionate and comprehensive care to our patients and their families. Our objective is to manage cases only as long as required to identify and resolve the initial crisis, and to work in conjunction with the referring veterinarian for follow-up patient care.

What We Do

Diagnostics Procedures Include

  • Computed Axial Tomography (CAT Scans)
  • Magnetic Resonance Imaging (MRI)
  • Cerebral spinal fluid (CSF) tap and analysis
  • Joint tap and analysis
  • Ultrasound guided aspirates and biopsies
  • Bone marrow analysis including core biopsies and aspirates
  • Continuous Glucose Monitoring (CGM)

Computed Axial Tomography (CAT Scans)
IndyVet was the first veterinary hospital to offer in-house Computed Axial Tomography (CAT Scans) in the greater Indianapolis area. Access to high quality transverse imaging allows us to diagnose and treat complex problems associated with the brain, spinal cord, spine, abdominal, thoracic, and pelvic cavities. Our 8 slice per rotation scanner generates extremely fast image acquisition and reconstructions allowing us to perform high-speed studies requiring only sedation rather than anesthesia.

Magnetic Resonance Imaging
IndyVet is the first private veterinary hospital in Indiana to offer in-house high field 1.5T MRI for patients. This imaging technique allows IndyVet to diagnose conditions of the brain, spinal cord, and other organs that cannot be identified with traditional radiography or CT. Having the capability of performing MRI 24 hours daily allows IndyVet to provide the highest level of patient imaging possible.

Continuous Glucose Monitoring (CGM)
Continuous Glucose Monitoring (CGM) is a probe placed under the skin of patients without the need for surgery. This allows patients to go home while blood sugar values are automatically collected and recorded for two to three days. Clients return on day three to have the implant removed (at no additional charge) and the data is downloaded and analyzed. Blood sugar values that were taken every five minutes plot a sugar curve allowing the identification of intermittent Somogyi phenomena, inappropriate administration techniques, or abnormal blood sugar values occurring during overnight hours. CGM provides a superior assessment of daily insulin activity by allowing normal patient activity at home without the stress of spending a day in the hospital for blood sugar sampling.

CGM is also useful for hospitalized diabetic ketoacidosis cases to avoid over- or under-dosing insulin in critical patients. In hydrated patients, it can reduce the number of blood samples required and may eliminate the need of jugular catheter placement for sampling in some patients. This monitoring has become the standard of care for human diabetics and now makes the management of veterinary diabetic patients easier as well.

Endoscopy Procedures Include

  • Laparoscopy
  • Rhinoscopy
  • Bronchoscopy
  • Cystoscopy
  • Upper GI endoscopy (Gastroduodenoscopy)
  • Lower GI endoscopy (Colonoscopy)
  • Thoracoscopy

IndyVet’s highly trained specialists offer the latest technology in both rigid and flexible video-endoscopy. Rhinoscopy, upper GI endoscopy, colonoscopy, cystoscopy, and otoscopy are some of the routine diagnostic procedures performed. Minimally invasive thoracoscopic and laparoscopic examinations are performed for the purpose of thoracic and abdominal biopsies and medical procedures.

Imaging Procedures include

  • Digital radiography
  • Ultrasound
  • Echocardiography
  • CT/MRI

Our skilled specialists rely on ultrasound for imaging of the abdomen, pelvic cavity, and thoracic cavity. Ultrasound examination in conjunction with minimally invasive guided needle aspirates or biopsies are a daily occurrence at IndyVet. Tissue or cytology samples obtained with ultrasound guidance can often be done on an out-patient basis, providing rapid and accurate diagnoses.


Echocardiograms, utilizing color flow Doppler, are performed routinely at IndyVet. Echocardiograms evaluate the anatomy and functional capacity of the heart and are an invaluable tool to assist in diagnosing and treating heart disease.


  • IV nutrition (TPN or PPN)
  • Stomach feeding tubes (endoscopically placed)
  • Esophageal feeding tubes

What To Expect

The IndyVet internal medicine team is committed to providing the most innovative and compassionate care for your pet in partnership with your family veterinarian.

The following guidelines will hasten the diagnosis and treatment of incoming patients:

  • Please do not feed your pet after midnight the night before your appointment unless otherwise directed.
  • Ask your family veterinarian to e-mail, fax, or provide you with prior lab work, imaging reports, and past treatment related to your pet’s problem or illness.

At your initial visit, an IndyVet internal medicine doctor will examine your pet, review their medical history, and will talk with you about your pet’s condition to recommend any diagnostic tests, or to suggest an appropriate course of medical therapy. Many pets can be managed on an outpatient basis while others may need to spend several days in the hospital undergoing a comprehensive evaluation and treatment.

Afternoon and evening visiting hours assures hospitalized patients and their families the opportunity to spend quality time together.

Patients are discharged on an appointment basis. Complete written instructions will be reviewed with each pet owner at the time of discharge to address any questions they may have regarding patient care at home.
