70491 Computed tomography, soft tissue neck; with contrast material(s)

Name of the Procedure:

Computed Tomography (CT) Scan of the Soft Tissue Neck with Contrast Material(s)

Summary

A CT scan of the soft tissue neck with contrast material is an imaging procedure that uses special X-ray equipment and a contrast dye to create detailed pictures of the tissues and structures in the neck.

Purpose

This procedure is used to identify abnormalities such as tumors, infections, inflammation, vascular anomalies, or other medical conditions affecting the soft tissues, muscles, or glands in the neck. The goal is to provide a clear, detailed image that helps in accurate diagnosis and treatment planning.

Indications

• Persistent neck pain or swelling
• Difficulty swallowing
• Hoarseness or change in voice
• Suspected tumors or masses
• Unexplained weight loss or fatigue
• Follow-up after neck surgery
• Evaluation of congenital anomalies

Preparation

• Fasting for several hours before the procedure (usually 4-6 hours)
• Allergies to iodine or contrast material should be discussed with the healthcare provider
• Removal of any metal objects, jewelry, or dentures
• Pre-procedure blood tests to assess kidney function

Procedure Description

1. The patient will lie on a motorized table that moves into the CT scanner.
2. An intravenous (IV) line will be inserted into the arm to administer the contrast dye.
3. The contrast dye is injected, and it may cause a warm sensation or metallic taste in the mouth.
4. The scanner rotates around the patient, taking multiple X-ray images from different angles.
5. The computer processes these images to create cross-sectional views of the neck’s soft tissues.
6. The radiologist reviews the images for any abnormalities.

Duration

The entire procedure typically takes about 30 to 60 minutes, including preparation and scanning time.

Setting

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

Personnel

• Radiologist (a doctor specializing in medical imaging)
• Radiologic technologist
• Nurse (if needed for assistance with the IV and monitoring)

Risks and Complications

• Exposure to a small amount of radiation
• Allergic reaction to contrast material (itching, rash, or more severe reactions)
• Kidney function impairment (particularly in patients with pre-existing kidney conditions)
• Discomfort from lying still for an extended period

Benefits

• High-resolution images that help in accurate diagnosis
• Non-invasive and relatively quick
• Guides treatment planning and can monitor effectiveness of treatment

Recovery

• Most patients can resume normal activities immediately after the procedure
• Hydration is encouraged to help flush out the contrast material
• Follow-up appointments may be needed to discuss the results with the healthcare provider

Alternatives

• MRI (Magnetic Resonance Imaging), which does not use ionizing radiation but may be less detailed for certain tissues
• Ultrasound, although it might not provide as much detail for deeper structures
• Physical examination and symptom management, depending on the severity of the condition

Patient Experience

Patients might feel anxious but are usually comfortable. The IV insertion may cause brief discomfort. The scanning process is generally painless, with possible mild claustrophobia in some patients. Post-procedure, patients typically feel normal, though they should monitor for any delayed allergic reactions to the contrast material.
