70492 Computed tomography, soft tissue neck; without contrast material followed by contrast material(s) and further sections

Name of the Procedure:

Computed Tomography (CT) of Soft Tissue Neck without Contrast Material followed by Contrast Material(s) and further sections

Summary

Computed tomography (CT) of the soft tissue neck is an imaging procedure that produces detailed cross-sectional images of the neck's soft tissues. The procedure initially captures images without contrast material and then uses contrast material to highlight structures, providing more detailed information.

Purpose

This procedure is used to diagnose and evaluate a variety of conditions affecting the structures and organs in the neck, such as tumors, infections, inflammation, vascular anomalies, and congenital abnormalities. The primary goal is to provide a comprehensive view that aids in accurate diagnosis and treatment planning.

Indications

• Unexplained neck pain or swelling
• Suspected tumors or masses in the neck
• Enlarged lymph nodes
• Infections or abscesses
• Vascular irregularities
• Postoperative evaluations
• Trauma to the neck

Preparation

• Fasting for 4-6 hours prior if contrast material is to be used
• Informing the healthcare provider about any allergies, particularly to iodine or shellfish
• Discontinuing certain medications as instructed by the healthcare provider
• Undergoing preliminary blood tests to check kidney function

Procedure Description

1. The patient lies on a motorized table that slides into the CT scanner.
2. Initially, images are taken without contrast material.
3. An intravenous (IV) line is then started if contrast material is to be used.
4. Contrast material is injected, and additional images are taken.
5. The patient must remain still during imaging to ensure clear, accurate images.
6. The table may move slightly to reposition the patient for different angles.

Duration

The entire procedure typically takes about 30 to 45 minutes.

Setting

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

Personnel

• Radiologist
• Radiologic technologist
• Nurse (if IV contrast is administered)

Risks and Complications

• Exposure to low levels of radiation
• Allergic reaction to contrast material
• Kidney function impairment (rare)
• Injection site reactions

Benefits

• Provides detailed images for accurate diagnosis
• Non-invasive with minimal discomfort
• Helps in planning treatment strategies

Recovery

• Patients can typically resume normal activities immediately following the procedure.
• Hydration is encouraged to help flush out the contrast material.
• Follow-up with the healthcare provider to discuss results.

Alternatives

• Magnetic Resonance Imaging (MRI): Provides detailed images without radiation but may not be suitable for patients with certain implants.
• Ultrasound: Non-invasive and radiation-free but less detailed for deeper structures.
• Biopsy: Direct sampling of tissue but is more invasive.

Patient Experience

• Patients might feel a warm sensation during the injection of contrast material.
• The procedure is generally painless, though some discomfort from lying still might occur.
• Pain management is usually not necessary, and instructions are provided for any immediate post-procedure care.
