Sacrum computed tomography

Computed tomography (CT) of the sacrum is an advanced diagnostic imaging method used to provide detailed visualization of the sacrum, a triangular bone located at the base of the spine between the lumbar spine and the coccyx. This examination produces detailed images of the bony structures, sacroiliac joints, and surrounding soft tissues, helping to identify a wide range of pathological conditions.

What is a Sacral CT Scan?

Computed tomography (CT) is an imaging technique that uses X-rays and computer processing to create detailed cross-sectional images of the body's internal structures. A sacral CT scan is particularly useful for evaluating bony anatomy, including the sacrum and sacroiliac joints, and for detecting degenerative changes, fractures, tumors, and inflammatory conditions.

When is a Sacral CT Scan Performed?

This examination is commonly performed when the following sacral conditions are suspected or diagnosed:

• Sacral pain: Chronic or acute pain in the sacral region with an unclear cause.
• Trauma: Sacral fractures or fissures.
• Inflammatory diseases: Sacroiliitis (inflammation of the sacroiliac joint), spondylitis.
• Tumors: Primary or metastatic tumors involving the sacrum.
• Infections: Infections of the sacrum or surrounding tissues.
• Preoperative and postoperative assessment: For surgical planning or evaluation of treatment outcomes.
• Pelvic pain of unknown origin: When the cause is suspected to be related to sacral pathology.

Examination Procedure at the Clinic

A sacral CT scan is performed in the radiology department.

1. Preparation: The patient lies on the CT examination table. You may be asked to remove metal objects, such as jewelry.
2. Scanning: The CT scanner acquires a series of X-ray images while the patient remains on the table. It is important to stay still throughout the examination.
3. Contrast agent (if required): In some cases, an intravenous contrast agent may be administered to obtain more detailed images.
4. After the procedure: The patient is observed for a short period of time.

The procedure is quick and is generally well tolerated.

Interpretation of Results

The CT images are evaluated by a radiologist. The assessment includes the bony structures of the sacrum, the sacroiliac joints, and the surrounding soft tissues, with particular attention to pathological changes such as fractures, tumors, inflammation, or degenerative abnormalities. The results are provided as a written radiology report together with the image set. These findings are an important source of information for the treating physician, such as an orthopaedic trauma surgeon or a neurologist, helping to establish an accurate diagnosis and develop an appropriate treatment plan.
