78013 Thyroid imaging (including vascular flow, when performed)

Name of the Procedure:

Thyroid Imaging (including Vascular Flow, when performed)

Summary

Thyroid imaging is a medical procedure that uses ultrasound to visualize the thyroid gland and, when necessary, its blood flow. The technology allows doctors to assess the size, shape, and function of the thyroid, as well as detect any lumps, nodules, or abnormalities.

Purpose

• To evaluate the thyroid gland's structure and function.
• To identify and assess lumps, nodules, or other abnormalities.
• To evaluate blood flow within the thyroid gland and surrounding tissues.
• To help diagnose conditions such as thyroiditis, goiter, and thyroid cancer.

Indications

• Symptoms of thyroid dysfunction (e.g., fatigue, weight changes, irregular heartbeats)
• A palpable lump or swelling in the neck
• Abnormal thyroid function tests
• Monitoring known thyroid conditions
• Preoperative evaluation and postoperative monitoring

Preparation

• No special dietary restrictions or fasting required.
• Wear comfortable, loose-fitting clothing and avoid neck jewelry.
• Inform the healthcare provider of any medications, especially blood thinners.
• No prior diagnostic tests are generally needed.

Procedure Description

1. You lie down on an examination table with your neck exposed.
2. A gel is applied to your neck to ensure good contact for the ultrasound probe.
3. The ultrasound probe (transducer) is moved over your neck to visualize the thyroid gland.
4. If vascular flow evaluation is needed, Doppler ultrasound is used to assess blood flow.
5. Images are displayed on a monitor and recorded for analysis.

Duration

The procedure typically takes about 30 minutes.

Setting

The procedure is performed in a radiology department, outpatient clinic, or physician's office.

Personnel

• Radiologist or a specially trained ultrasound technician (sonographer)
• Occasionally, the referring physician may be present

Risks and Complications

• Generally minimal risks as it is a non-invasive and radiation-free procedure.
• Rarely, minor discomfort from the pressure of the transducer on the neck.
• No significant complications are expected.

Benefits

• Provides detailed images of the thyroid and surrounding tissues.
• Helps in early detection and diagnosis of thyroid conditions.
• Non-invasive, painless, and relatively quick.

Recovery

• No recovery time is needed.
• You can resume normal activities immediately following the procedure.
• Your doctor will discuss the results with you, usually within a few days.

Alternatives

• Blood tests to measure thyroid hormone levels
• Thyroid scintigraphy (nuclear medicine)
• CT or MRI scans for more detailed imaging
• Physical examination, though less accurate

Patient Experience

• You may feel a slight pressure on your neck from the ultrasound probe.
• The procedure is painless and generally well-tolerated.
• The gel might feel a bit cold and sticky but is easily wiped off afterward.
• If vascular flow is assessed, you might hear a whooshing sound from the Doppler ultrasound.
