Name of the Procedure:
Computed Tomography, Bone Mineral Density Study, 1 or More Sites, Axial Skeleton (eg, hips, pelvis, spine)
Summary
A computed tomography (CT) bone mineral density study is a specialized imaging test that measures the density and strength of bones in the axial skeleton, which includes the hips, pelvis, and spine. This test helps in evaluating bone health and diagnosing conditions like osteoporosis.
Purpose
The procedure is used to assess bone density and detect osteoporosis or other conditions that cause weakened bones. The primary goal is to identify patients at risk for fractures and to monitor the effectiveness of treatment for bone-related conditions.
Indications
- History of fractures
- Significant loss of height
- Chronic conditions or treatments affecting bone density (e.g., rheumatoid arthritis, long-term steroid use)
- Postmenopausal women and older men
- Family history of osteoporosis
Preparation
- Wear loose, comfortable clothing without metal fasteners.
- Avoid taking calcium supplements 24 hours before the test.
- Generally, no fasting or special medication adjustments are required.
- Inform the technician if there is a possibility of pregnancy.
Procedure Description
- The patient lies on a cushioned table.
- A scanning device rotates around the body, taking detailed images of the axial skeleton.
- The procedure is non-invasive, and typically no contrast dye is needed.
- The patient must stay still during the scanning process to ensure clear images.
Duration
The procedure typically takes about 10 to 30 minutes.
Setting
Performed in an outpatient radiology center or a hospital radiology department.
Personnel
- Radiologist
- Radiologic technologist
Risks and Complications
- Exposure to a small amount of radiation
- Rarely, there may be allergic reactions to contrast dye, if used
Benefits
- Accurate assessment of bone density and structure
- Early detection of osteoporosis, allowing timely intervention
- Non-invasive and relatively quick procedure
Recovery
- No recovery time is needed; patients can typically resume normal activities immediately.
- Follow-up appointments may be scheduled to review results and plan treatment if necessary.
Alternatives
- Dual-energy X-ray absorptiometry (DEXA) scan: Often used as standard bone density test, quicker and with less radiation.
- Ultrasound of the heel: Non-radiation option but less comprehensive.
- Blood tests to measure calcium and Vitamin D levels.
Patient Experience
- The procedure is generally painless.
- Patients might feel slight discomfort from staying still during the scan.
- Any anxiety about the procedure can be addressed by discussing concerns with the radiologic technologist.
Pain management and comfort measures include positioning aids and reassurance from the healthcare team.
