Diagnostic imaging services

Our radiologists provide various diagnostic imaging services to help your doctors diagnose any possible gastrointestinal disorders or diseases you may have. The results of these imaging procedures and tests can also help with early detection of colon cancer. Many of our imaging services have been accredited by the American College of Radiology.

Gastrointestinal (GI) conditions we treat

We treat various GI conditions to ensure your best digestive health.

Barrett's esophagus

Barrett's esophagus occurs when the normal tissue of the esophagus is replaced with an abnormal growth of tissue similar to the lining of the intestine. This disorder is often diagnosed in people who have chronic gastroesophageal reflux disease (GERD). It is considered to be precancerous and requires careful treatment after it is diagnosed.

Colon polyps

These mushroom-shaped growths occur on the inner lining of the colon. They may be as small as a pea or larger than a plum. Colon polyps start out as benign tumors but may become malignant over time. The larger the polyp, the more likely it is to contain cancer cells.


Small, bulging pouches formed on the walls of the intestine are called diverticula. Diverticulitis occurs when one or more of these pouches becomes infected or inflamed. These infected pouches cause symptoms ranging from mild discomfort to extreme pain with severe tenderness and fever. Treatment for diverticulitis requires antibiotics and resting of the bowel by avoiding food or, at times, even liquids. For severe cases, hospitalization is required.

Ulcers of the GI tract

An ulcer is an open sore in the lining of the stomach or intestine. Peptic ulcers are eventually caused by acid and pepsin, a digestive stomach enzyme. The two types of peptic ulcers include gastric ulcers—which occur in the stomach—and duodenal ulcers—which occur in the first portion of the intestine.

Digestive health services

We offer an array of procedures to treat any GI-related conditions and improve your overall digestive health. Some of these services include:

Esophagogastroduodenoscopy (EGD)

This procedure uses a flexible high-definition videoscope to directly view the digestive tract—from the mouth to the small intestine.

EGD is used to:

  • Diagnose digestive disorders
  • Monitor any existing conditions
  • Perform biopsies and interventions of the gallbladder and bile duct
  • Remove harmful substances, including stone removal


This diagnostic procedure allows physicians to view the intestinal tract from the rectum to the colon. A colonoscopy uses a small, flexible tube with a tiny camera on the end, which is inserted into the rectum.

A colonoscopy is used to detect abnormalities in the colon and rectum. It is the most common method used to screen for colon cancer.

Colonoscopies are used to:

  • Perform biopsies
  • Remove polyps
  • Diagnose various digestive health issues

Endoscopic retrograde cholangiopancreatography (ERCP)

During ERCP, a dye is injected into the bile and pancreatic ducts using a flexible video endoscope. Real time X-ray is used to outline the bile ducts and pancreas. Often, the procedure is performed to view blockages of the bile duct from either stones or stricture.
