What is a MRI Sacroiliac Joints?
MRI (Magnetic Resonance Imaging) uses powerful magnets and radiofrequency waves — with no ionising radiation — to create high-resolution cross-sectional images.
A MRI Sacroiliac Joints allows your radiologist to examine:
- The sacroiliac joints themselves, including the joint space and surfaces.
- The surrounding ligaments that support the SI joints.
- The sacrum and ilium bones where they form the joints.
- Adjacent soft tissues, such as muscles and tendons near the SI joints.
MRI offers unmatched soft-tissue contrast and is widely used in specialist care for diagnosing and following-up disease of the sacroiliac joints.

Symptoms that may warrant a MRI Sacroiliac Joints

- Persistent lower back pain, particularly if it's worse in the morning or after rest.
- Pain that radiates into the buttocks or down one or both legs.
- Stiffness in the lower back or hips, especially upon waking.
- Pain that improves with activity but worsens with inactivity.
- A feeling of instability or clicking in the pelvic area.
- Pain that makes it difficult to stand up from a seated position.

What can a MRI Sacroiliac Joints detect?
MRI is highly effective in detecting:
- Inflammation within the SI joints, which can be a sign of conditions like sacroiliitis.
- Degenerative changes or arthritis affecting the joint surfaces.
- Fluid collections or swelling around the joints.
- Stress fractures or other bone abnormalities in the sacrum or ilium.
- Ligament tears or sprains contributing to joint instability.
- Possible signs of infection or other less common joint pathologies.

Frequently asked questions
How long does an MRI of the sacroiliac joints take?
A typical MRI scan of the sacroiliac joints takes between 30 to 45 minutes for the scan itself. Your appointment will be longer to allow for preparation and for you to get settled.
Will I need contrast dye for my SI joint MRI?
Contrast dye is not always necessary for SI joint scans. If your referring clinician believes it's needed to highlight certain tissues or inflammation, it can be added for an additional charge. This will be discussed with you before booking.
Can I have an MRI if I have metal in my body?
Many implants are MRI-safe, but it's crucial to inform us about any metal implants or fragments you have. We will check each item individually to ensure your safety before the scan proceeds.
What happens after my SI joint MRI scan?
Your scan images will be reviewed by a UK-certified Consultant Radiologist. You'll receive your detailed report within 3 working days via your secure online patient portal, which you can access, download, and share with your GP or specialist.
How quickly can I get a scan?
Most MRI, ultrasound, and X-ray scans at MyScanHub can be booked same-day or next-day. Walk-in slots are available for X-rays most weekdays.
Do I need a GP referral?
No — MyScanHub accepts self-referral for most scans. Our consultant radiologists review every case. Some scans (e.g. contrast studies) do need a referring clinician; we'll let you know at booking.
