MRI Enterography

What is MRI enterography?

MRI enterography is a radiological diagnostic method that provides detailed imaging of the small intestine using magnetic resonance. This non-invasive procedure relies on a strong magnetic field and electromagnetic waves (radio waves). The imaging is achieved by altering the position of protons in the tissues relative to the magnetic field, and as protons return to their initial position, they release energy, i.e., signals, which are used to create images of the intestines on a computer.

Since it does not use harmful ionizing radiation, MRI enterography has an advantage over CT enterography.

For better visualization of the area of interest, an oral contrast agent is used to distend the intestines, and a spasmolytic agent is administered intravenously, along with a contrast agent as indicated.

When is MRI enterography indicated?

This radiological method is used for diagnosing patients with:

• Crohn’s disease
• Ulcerative colitis
• Celiac disease

In these conditions, MRI is useful for detecting possible complications such as fistulas and strictures (narrowing) of the intestines.

It is also used to assess postoperative adhesions and malignant or other pathological changes in the intestines.

What does MRI enterography show?

MRI enterography can visualize:

• Areas of inflammation
• Abscesses
• Fistulas (abnormal connections between the intestine and other structures resulting from inflammatory processes)
• Structures
• Intestinal obstructions
• Various pathological formations

Duration of MRI enterography

The scan, including preparation, typically takes about 30 minutes.

Preparation for MRI Enterography

Special preparation of the digestive system is required before the procedure, which includes:

• A special diet 2 to 3 days before the scan
• Fasting for 4 to 6 hours before the examination

Before the scan, you will receive a special syrup to distend the small intestine for better visualization, and a spasmolytic agent will be administered intravenously to reduce intestinal peristalsis. An intravenous contrast agent will also be used during the procedure.

You must remove all metal objects that may be affected by the MRI device’s magnetic field: jewelry, piercings, glasses, mobile phones, keys, watches, credit cards, metal hair accessories, and removable dental prosthetics.

Wear clothing without metal parts (buttons, zippers, clasps).

If you are prone to claustrophobia, you may take a mild sedative 15 to 30 minutes before the examination.

Risks of MRI

MRI enterography is a completely safe method for examining the intestines without exposure to harmful ionizing radiation.

However, the MRI device resembles a tunnel, and the confined space may trigger claustrophobia in some individuals. At Poliklinika Sinteza, we use the Siemens MAGNETOM® Aera MRI device, known for its open design (70 cm tunnel width and 145 cm length), which reduces the feeling of enclosure and provides a more comfortable experience.

Due to the use of a strong magnetic field, MRI is contraindicated for patients with a cardiac pacemaker or implanted cardioverter-defibrillator.

The MRI procedure

• Upon arrival at the clinic, you will receive a questionnaire about your health status.
• Preparation for the examination includes administering the oral contrast agent to distend the intestines and the intravenous spasmolytic agent. Our staff will carefully guide you through the procedure.
• Before the scan, all metal objects and clothing containing metal must be removed.
• You will then be positioned lying on your stomach inside the MRI device, which is tunnel-shaped.
• The MRI machine produces loud noises during the scan. The MRI machine produces loud noises during the scan.
• During the scan, you will be alone in the room (the staff will be in the control room), but you can communicate with them via intercom. You will also have a small device to signal if you need to stop the scan. The staff may give you instructions via intercom during the scan, such as asking you to momentarily hold your breath.

Movement: It is important to stay still during the scan to ensure high-quality images.

Recovery from MRI enterography

Due to the use of oral contrast, you may experience cramps, abdominal discomfort, and diarrhea for up to 24 hours after the procedure.

In some cases, you might feel drowsy or dizzy from lying still.

If a sedative was taken, wait until its effects wear off before driving. If a contrast agent was used, drink plenty of fluids throughout the day.

Precautions

Since a strong magnetic field is used during an MRI, it is essential to inform the radiology staff before the scan about the presence of metal objects in or on your body, including: cardiac pacemakers, metal clips, removable dentures, insulin pumps, stents or clips in blood vessels, neurostimulators, artificial heart valves, artificial joint prostheses, cochlear implants, metal fragments or shrapnel, tattoos, or permanent makeup containing metals. Some of these items may not be contraindications, but confirmation from the operator is required.

If intravenous contrast is indicated, inform the staff of any kidney-related health issues.

MRI is recommended for pregnant women only in cases of strong medical indications, and typically after the first trimester.

For a better patient experience:

• Comfortable MRI room design
• Soft patient support during the scan
• Noise reduction with special patient ear protection
• Audio instructions and support throughout the scan

Technical specifications:

• Tunnel diameter: 70 cm
• Tunnel length: 1.37 m
