Name of the Procedure:

Computed Tomography, Thoracic Spine; Without Contrast Material

Common name(s): CT scan of the thoracic spine without contrast

Summary

A computed tomography (CT) scan of the thoracic spine without contrast is a diagnostic imaging procedure that uses X-rays to create detailed cross-sectional images of the middle segment of the spine. Unlike other scans, it does not involve the injection of contrast material.

Purpose

This procedure helps in diagnosing and evaluating problems related to the thoracic spine, such as spinal injuries, tumors, infections, or degenerative diseases. It aims to provide clear images for accurate diagnosis and to guide further treatment.

Indications

• Persistent back pain
• Suspected spinal injuries or fractures
• Signs of tumors or metastatic disease
• Neurological symptoms like numbness or weakness
• Suspected infections like osteomyelitis
• Degenerative spine conditions such as herniated discs

Preparation

• No special preparation is required.
• Patients may be asked to wear a hospital gown and remove any metal objects, such as jewelry and belts, that might interfere with the imaging.

Procedure Description

1. The patient will lie on a moveable table attached to the CT scanner.
2. The table will slide into a large, doughnut-shaped machine.
3. The patient must remain still during the scan to ensure clear images.
4. The CT machine will take a series of detailed X-ray images from different angles.
5. A computer will compile these images to create cross-sectional views of the thoracic spine.

Tools and equipment: CT scanner, computer with specialized software.

Anesthesia or sedation: Not required.

Duration

The procedure typically takes about 10 to 15 minutes.

Setting

The procedure is usually performed in a hospital radiology department or an outpatient imaging center.

Personnel

• Radiologist (interprets the images)
• Radiologic technologist (operates the CT scanner)
• Additional support staff, if needed

Risks and Complications

• Exposure to a low dose of radiation.
• Extremely rare risk of allergic reaction if inadvertently exposed to contrast material in the vicinity.

Benefits

• Non-invasive and quick procedure.
• Provides detailed images that can help in accurate diagnosis.
• Helps guide further treatment effectively.

Recovery

• No recovery time is required.
• Patients can resume normal activities immediately after the procedure.
• Follow-up with the referring physician to discuss the results.

Alternatives

• Magnetic Resonance Imaging (MRI): More detailed images of soft tissues; no radiation exposure but may be contraindicated for patients with metal implants.
• X-ray: Less detailed images, but quicker and with lower radiation exposure.
• Bone scans or PET scans: Used in specific conditions like cancer but involves exposure to radioactive tracers.

Patient Experience

• The patient may feel a slight discomfort from having to lie still.
• The scanner can be noisy, but headphones may be provided to improve comfort.

• Generally, the procedure is painless, and measures are taken to ensure the patient’s comfort during the scan.

  Pain management and comfort measures: Most patients do not experience pain, but for those with pre-existing back pain, support and positioning cushions can be used for comfort.
