MRI Pelvis with and without contrast

What is an MRI of the Pelvis with and Without Contrast?

An MRI (Magnetic Resonance Imaging) of the pelvis with and without contrast is a diagnostic imaging procedure that uses magnetic fields and radio waves to create detailed images of the pelvic region. The pelvis includes structures such as the bladder, reproductive organs, lymph nodes, blood vessels, and surrounding tissues.

  • Without contrast: Initial images provide a baseline view of the pelvic anatomy.
  • With contrast: A gadolinium-based contrast agent is injected to enhance the visibility of blood vessels, tumors, and areas of inflammation or infection. This helps to identify subtle or complex abnormalities.

Why is it Done?

This test may be recommended to evaluate:

  • Reproductive organs: Uterus, ovaries, and prostate (to detect tumors, cysts, or other abnormalities)
  • Bladder or rectum: For conditions like tumors, fistulas, or inflammation
  • Pelvic pain or unexplained symptoms: To assess the cause of chronic pain or other concerns
  • Lymph nodes: To detect swelling or metastatic disease
  • Injuries or fractures: To examine trauma to the pelvic bones or soft tissues
  • Cancer staging: To evaluate the spread of pelvic cancers
  • Endometriosis or fibroids: In women with pelvic pain or menstrual irregularities

What to Expect

Before the Procedure:

  • Preparation:
    • Fasting: You may be asked to refrain from eating for a few hours before the scan.
    • Metal Objects: Remove all jewelry, watches, and metal-containing items (clothing with zippers or underwire bras).
  • Medical History:
    • Inform your doctor about any metal implants, pacemakers, or pregnancy.
    • Share any history of allergies to contrast agents or kidney problems.

During the Procedure:

  1. Positioning:
    • You’ll lie on a motorized table that slides into the MRI machine. Pillows or cushions may be used for comfort.
  2. Imaging Without Contrast:
    • Initial images are taken to observe the natural anatomy of the pelvic area.
    • You’ll need to remain still. The machine will make loud noises, and earplugs or headphones may be provided.
  3. Contrast Injection:
    • A gadolinium-based contrast agent will be injected into a vein in your arm.
    • Some people feel a mild cool sensation or warmth when the contrast is administered.
  4. Imaging With Contrast:
    • Additional images will be captured to highlight blood flow and abnormal areas.
    • You may be asked to hold your breath briefly during certain parts of the scan for better clarity.

The scan typically lasts 30–60 minutes.

After the Procedure:

  • If contrast was used, drink plenty of water to help your body eliminate it.
  • You can resume normal activities unless otherwise instructed.
  • Rarely, you may experience mild side effects, such as nausea or a rash. Contact your doctor if you notice unusual symptoms.

What the Results May Show:

  • Normal Results: Healthy pelvic organs, bones, and surrounding tissues.
  • Abnormal Results:
    • Tumors or cysts in the bladder, uterus, ovaries, prostate, or lymph nodes
    • Infections, abscesses, or inflammation
    • Fibroids or endometriosis
    • Bone fractures or injuries
    • Vascular abnormalities, such as aneurysms or blood clots
    • Signs of cancer or metastasis

Your healthcare provider will review the findings and discuss any next steps, such as additional testing or treatment.
