Chronic inflammatory bowel diseases (IBD) such as Crohn’s disease and ulcerative colitis affect millions of people across the United States, including many here in Buffalo and Western New York. Managing these conditions is an ongoing process — and medical imaging has become a critical part of how doctors diagnose, monitor, and guide treatment over time.

At Great Lakes Medical Imaging (GLMI), we support gastroenterologists and primary care providers by offering advanced, non-invasive imaging that helps evaluate the health of the digestive tract and monitor disease activity. Our CT, MRI, and ultrasound services help patients with Crohn’s and colitis get the answers they need — without invasive procedures when possible.

Why Imaging Matters in Crohn’s and Colitis Management

While endoscopy remains an important diagnostic tool, imaging plays a complementary — and often more convenient — role. With IBD, the disease process extends beyond what can be seen with a colonoscope. Imaging allows doctors to evaluate the entire bowel, identify inflammation in deeper layers of the intestinal wall, and monitor complications such as abscesses, strictures, or fistulas.

Imaging also provides a non-invasive way to assess disease progression and treatment response — especially in patients who experience frequent flare-ups or worsening symptoms.

Types of Imaging Used for IBD Patients

CT Enterography (CTE)

This specialized CT scan uses oral contrast and low-dose radiation to produce detailed images of the small intestine. CT enterography is particularly useful in evaluating Crohn’s disease, which commonly affects areas of the small bowel not easily accessible by endoscopy.

CTE can detect:

• Active inflammation
• Bowel wall thickening
• Abscesses or fistulas
• Intestinal obstructions or strictures

It’s fast, non-invasive, and widely available — making it a first-line imaging choice for many providers managing IBD patients.

MR Enterography (MRE)

MR enterography provides similar insights to CT enterography but without ionizing radiation, making it an ideal option for younger patients or those requiring repeated studies. It offers excellent visualization of bowel wall inflammation, fistulas, and perianal disease.

With high-field MRI systems at GLMI, we deliver clear, high-resolution images that help guide treatment decisions while minimizing radiation exposure.

Abdominal Ultrasound

In some cases, especially in children or during pregnancy, ultrasound may be used as a first step to evaluate the intestines. It can detect wall thickening, enlarged lymph nodes, and fluid collections. While not as comprehensive as CT or MRI, it’s useful in certain clinical settings due to its safety, speed, and accessibility.

Monitoring Treatment Response and Complications

For IBD patients, imaging is not only useful at diagnosis — it plays a key role in long-term care. Your physician may order imaging to:

• Track the effectiveness of medications like biologics or steroids
• Check for complications (e.g., abscesses or bowel narrowing)
• Evaluate pain or flare-ups that aren’t fully explained by labs or symptoms
• Reduce reliance on frequent colonoscopies

With each scan, radiologists can compare current findings to prior images, giving your care team a clear picture of how your condition is progressing — or improving.

What to Expect During Your Exam

Your provider will work with our team to determine the right imaging modality based on your symptoms, history, and goals. Most exams are outpatient procedures that take 30–60 minutes, and our staff will ensure you are as comfortable and informed as possible.

You may be asked to drink contrast material prior to the scan and avoid eating for a few hours beforehand. After the exam, images will be reviewed by our radiology team and results sent directly to your provider for discussion.
