What is this test?
Magnetic Resonance Imaging (MRI) of the sacral spine is a specialized scan focusing on the sacrum—the large, triangular bone at the base of the spine that connects to the pelvis. This advanced imaging technique uses powerful magnets and radio waves to produce highly detailed, three-dimensional images of the sacral vertebrae, surrounding soft tissues, sacroiliac joints, nerves, and adjacent pelvic structures. MRI provides a radiation-free way to evaluate the sacral area for various medical conditions with exceptional clarity.
What is it used for?

• Diagnosing tumors, cysts, or other abnormal masses in the sacral bone or surrounding tissues
• Detecting infections such as osteomyelitis or sacroiliitis (inflammation of the sacroiliac joints)
• Evaluating trauma-related injuries including fractures or ligament damage in the sacral region
• Investigating unexplained pelvic, lower back, or tailbone (coccyx) pain
• Assessing nerve compression or inflammation affecting the sacral nerve roots, which may cause pain or neurological symptoms in the pelvis or lower limbs
• Guiding surgical planning for sacral or pelvic conditions
• Monitoring known sacral disorders or postoperative healing

Who should get this test?

• Patients experiencing chronic or acute tailbone pain, pelvic discomfort, or lower back pain that cannot be explained by other imaging
• Individuals with suspected sacral fractures or trauma following injury
• Those with symptoms suggestive of sacroiliac joint inflammation or infection
• Patients with neurological symptoms such as numbness, tingling, or weakness in the legs or pelvic region potentially linked to sacral nerve involvement
• Individuals requiring detailed assessment of sacral tumors, cysts, or other lesions
• Patients undergoing follow-up evaluation for sacral disease or post-surgical outcomes

Preparation Required:

• Standard MRI preparation includes removing all metal objects, jewelry, and accessories
• Inform the MRI staff about any implanted devices, pacemakers, or metal fragments in your body
• No fasting or medication restrictions are usually necessary unless contrast dye will be administered, in which case you will receive specific instructions

How is the procedure performed?
You will lie on the MRI table in a comfortable position, often on your back or stomach, depending on the scanner setup. The sacral region will be centered within the magnetic field. The scan usually takes between 20 and 40 minutes. It is essential to remain still during imaging to ensure sharp, high-quality images. The MRI machine produces a series of loud knocking or tapping sounds during the scan, and you will be provided ear protection. Contrast agents may sometimes be used to enhance visualization of inflammation, infection, or tumors, after assessing kidney function and allergy history.
Risks & Safety:

• MRI uses no ionizing radiation and is considered very safe
• Gadolinium contrast agents, if used, are generally safe but require kidney function evaluation before administration
• Patients with claustrophobia or anxiety may experience discomfort and can discuss sedation options with their doctor
• MRI is contraindicated for patients with certain non-compatible implants or metallic foreign bodies

Results:
A radiologist specializing in musculoskeletal imaging reviews the detailed MRI scans and provides a comprehensive report describing the condition of the sacral bones, joints, nerves, and surrounding soft tissues. The report identifies any fractures, infections, tumors, inflammation, or nerve impingement, helping your doctor tailor an effective treatment plan.
Short Statement:
A focused MRI scan of the sacrum—your spine’s triangular base—offering detailed insight into tailbone pain, sacroiliac joint inflammation, tumors, or nerve-related issues for precise diagnosis and management.
