Computed tomography, maxillofacial area; without contrast material, followed by contrast material(s) and further sections
CPT4 code
Name of the Procedure:
Computed Tomography (CT) of the Maxillofacial Area; Non-Contrast Followed by Contrast
Summary
A CT scan of the maxillofacial area involves taking detailed images of the facial bones and soft tissues using X-rays. Initially, images are taken without any contrast material, followed by additional scans after a contrast dye is injected to highlight specific structures.
Purpose
This procedure helps diagnose conditions affecting the facial bones, sinuses, and soft tissues, including fractures, infections, and tumors. The goal is to obtain clear, detailed images that can assist in accurate diagnosis and treatment planning.
Indications
- Facial trauma or suspected fractures
- Chronic sinusitis or sinus infections
- Tumors or abnormal growths in the facial region
- Dental issues, such as impacted teeth or cysts
Preparation
- Patients may need to fast for a few hours before the procedure.
- Pre-procedure blood tests may be required to assess kidney function.
- Remove all metallic objects from the head and neck area.
Procedure Description
- The patient lies on a motorized table that slides into the CT machine.
- Initial scans are taken without contrast material.
- A contrast dye is then injected, usually intravenously.
- Additional scans are taken to capture enhanced images of the maxillofacial area.
- The process uses a CT scanner, which rotates around the patient to take multiple images from various angles.
Duration
The entire procedure typically takes around 30-60 minutes.
Setting
Performed in a hospital radiology department or an outpatient imaging center.
Personnel
- Radiologist
- Radiologic technologist
- Nurse or healthcare professional for administering contrast material
Risks and Complications
- Exposure to radiation
- Allergic reaction to contrast dye
- Potential kidney issues related to contrast material
Benefits
- Provides precise, high-resolution images for accurate diagnosis.
- Helps in effective treatment planning.
- Results are often available quickly, aiding prompt medical decisions.
Recovery
- Most patients can resume normal activities immediately.
- Drink plenty of fluids to help flush out the contrast material.
- Follow-up appointments may be scheduled to discuss results.
Alternatives
- Magnetic Resonance Imaging (MRI): Offers detailed images without radiation but is less effective for bony structures.
- Ultrasound: Limited to soft tissues and less detailed.
- Standard X-rays: Quicker and cheaper but less detailed compared to CT.
Patient Experience
During the scan, the patient will need to lie still and may hear whirring sounds from the machine. Post-procedure, there may be a warm sensation from the contrast dye. Pain management is usually not necessary, but any discomfort from lying still can be addressed with guidance from the healthcare team.
