Computed tomography, thoracic spine; without contrast material, followed by contrast material(s) and further sections
CPT4 code
Name of the Procedure:
Computed Tomography, Thoracic Spine; without Contrast Material, followed by Contrast Material(s) and Further Sections
Common name(s): CT Scan of the Thoracic Spine with Contrast
Summary
This procedure involves taking detailed images of the thoracic (mid-back) spine using a computed tomography (CT) scanner. Initially, images are taken without using a contrast dye. Then, a contrast material is injected to enhance the visibility of specific structures, and further images are captured.
Purpose
The CT scan of the thoracic spine helps to diagnose and assess various spinal conditions, such as herniated discs, spinal stenosis, tumors, infections, fractures, and inflammatory diseases. The goal is to provide a detailed view of the spine’s anatomy for accurate diagnosis and to guide treatment planning.
Indications
- Persistent mid-back pain unexplained by other diagnostic methods.
- Suspected spinal tumors, infections, or fractures.
- Evaluation of spinal abnormalities identified in other imaging studies.
- Follow-up assessment of known spinal conditions.
- Pre-surgical planning and post-surgical evaluation.
Preparation
- Fast for 4-6 hours before the procedure if instructed.
- Inform your doctor of any allergies, especially to iodine or contrast dyes.
- Disclose all current medications and recent medical conditions.
- Blood tests may be required to assess kidney function and ensure you can safely receive the contrast dye.
Procedure Description
- Initial Scanning: You will lie on a motorized table that slides into the CT scanner. Initial images are taken without contrast material.
- Contrast Injection: An intravenous (IV) line is placed in your arm, and contrast material is injected.
- Further Imaging: Additional images are taken to highlight blood vessels and spinal structures.
- Completion: The IV is removed, and you may be observed for a short period for any adverse reactions.
Tools/Equipment: CT scanner, IV line, contrast dye.
No anesthesia or sedation is typically required.
Duration
The entire procedure generally takes about 30-60 minutes.
Setting
Performed in a hospital radiology department or an outpatient imaging center.
Personnel
- Radiologist
- Radiologic technologist
- Nurse (if IV placement and monitoring are required)
Risks and Complications
- Common: Mild allergic reactions to contrast dye (rash, itching).
- Rare: Severe allergic reactions (anaphylaxis), nephropathy (kidney issues) from contrast material.
Benefits
- Provides detailed images of spinal structures and abnormalities.
- Non-invasive with a relatively short duration.
- Helps in accurate diagnosis and treatment planning.
Recovery
- Most patients can resume normal activities immediately.
- Drink plenty of fluids to help flush out the contrast dye.
- Follow-up appointments may be scheduled to discuss results and further treatment.
Alternatives
- MRI of the thoracic spine: preferred for soft tissue evaluation but takes longer and may not be suitable for those with certain implants.
- X-ray: less detailed but useful for initial assessment of bone structures.
- Bone scan: used primarily for detecting spine metastases or unexplained bone pain.
Patient Experience
During the procedure, you might feel the table moving and hear whirring noises from the scanner. The contrast injection may cause a warm sensation or metallic taste temporarily. Post-procedure, mild discomfort at the IV site and increased urination due to the contrast dye are common. Pain management is usually not necessary, but any discomfort can be addressed with over-the-counter pain relievers if needed.
