A CT scan of the sacroiliac (SI) joint with contrast is typically done to evaluate the joint for inflammation or other conditions that can cause pain and mobility issues.
When this test is required
This test is usually requested when a patient is experiencing pain or mobility issues in the lower back, hips, or legs, and other diagnostic tests have been inconclusive or unclear.
What the Test Detects
The CT scan of the SI joint provides detailed images of the bones, soft tissues, and nerves in the area, allowing doctors to look for signs of inflammation, injury, or other conditions that may be causing pain or mobility issues.
Preparation for the Test
Patients will need to remove any metal objects from their body before the test and will be asked to lie still on a table while the scanner takes images. They may also be asked to drink a contrast dye beforehand to help improve the clarity of the images.
Sample Requirements
No sample is required for this test.
Additional Notes
Patients should inform their doctors if they are pregnant or may be pregnant before undergoing this test, as the radiation from the CT scan may be harmful to a developing fetus.
