CT Scan and Dedicated Scan of S.I Joint Without contrast

Specimen Required

Fasting Required

Purpose of the Test

A CT scan of the S.I joint without contrast is performed to diagnose various conditions affecting the S.I joint, such as inflammation, infection, arthritis, fractures, tumors, or abnormalities in the joint structure. The scan provides detailed images of the bones, muscles, and soft tissues around the joint, allowing doctors to detect any abnormalities that may be causing pain, stiffness, or mobility issues.

When this test is required

A CT scan of the S.I joint without contrast may be requested by a doctor when a patient experiences chronic lower back pain or other symptoms associated with S.I joint dysfunction, such as hip or groin pain. The test is often ordered when other imaging tests fail to provide a clear diagnosis.

What the Test Detects

A CT scan of the S.I joint without contrast is used to evaluate the bones, muscles, and soft tissues around the joint. It creates detailed images of the joint space, allowing doctors to look for signs of inflammation, infection, fractures, or abnormalities in the joint structure.

Preparation for the Test

In general, no special preparation is required for a CT scan of the S.I joint without contrast. However, patients should inform their doctor if they are pregnant, have a history of kidney problems, or have any allergies to contrast material or iodine. In some cases, the doctor may advise patients to avoid eating or drinking before the scan or to take medication to help them relax.

Sample Requirements

No sample is required for a CT scan of the S.I joint. It is a non-invasive imaging test that uses X-ray technology to produce images of the inside of the body.

Additional Notes

A CT scan of the S.I joint without contrast is a safe and non-invasive imaging test that typically takes only a few minutes to complete. However, it exposes patients to a small amount of radiation, so doctors only recommend it when necessary. Patients may experience mild discomfort during the test, such as lying flat on their back or holding their breath for a few seconds, but these are usually short-lived. After the scan, patients can resume their normal activities right away.
