MRI of the sacroiliac joint without contrast is often used to evaluate the joint for inflammation, infection, or tumors, and can be helpful in diagnosing conditions such as sacroiliitis, ankylosing spondylitis, and other types of arthritis.
When this test is required
An MRI of the sacroiliac joint without contrast may be requested by a doctor if a patient has persistent lower back, hip, or buttock pain that may be caused by sacroiliitis or other joint problems.
What the Test Detects
An MRI of the sacroiliac joint without contrast is used to create detailed images of the bones and soft tissues in the pelvis and lower back area. This can help detect abnormalities in the sacroiliac joint, which connects the sacrum bone in the lower back to the ilium bones in the pelvis.
Preparation for the Test
No specific preparation is usually required for an MRI of the sacroiliac joint without contrast. However, the patient will need to remove any metal objects or jewelry from their body, as these can interfere with the MRI images. Additionally, patients who have a history of claustrophobia may want to discuss the use of a mild sedative with their doctor.
Sample Requirements
No sample is required for an MRI of the sacroiliac joint without contrast.
Additional Notes
MRI of the sacroiliac joint is a safe and painless procedure that does not use ionizing radiation. However, it may not be recommended for patients who have certain types of metal implants or devices, such as pacemakers or cochlear implants, as these can be affected by the magnetic field.
