A head and neck ultrasound uses high-frequency sound waves to create real-time images of internal structures. This non-invasive diagnostic tool allows healthcare professionals to visualize soft tissues, organs, and blood vessels without using radiation. It is a safe option for examining various conditions in the head and neck.
Common Reasons for an Ultrasound
Doctors recommend a head and neck ultrasound to investigate a range of symptoms or conditions. A common reason is to evaluate the thyroid gland for the presence of nodules, growths, or tumors, with the ultrasound determining if these are solid or fluid-filled and assessing their size and blood supply. This scan also helps check lymph nodes for swelling or other abnormalities. Additionally, it can be used to assess the salivary glands, investigate unexplained lumps or masses in the neck, and examine the carotid arteries to evaluate blood flow.
How to Prepare
Preparing for a head and neck ultrasound is generally straightforward and requires minimal effort. Patients are advised to wear comfortable, loose-fitting clothing that allows easy access to the neck area. Removing jewelry, such as necklaces and earrings, is also recommended to prevent interference. Fasting is not usually necessary, and patients can eat and drink as usual. However, avoid applying lotions, creams, or makeup to the neck area on the day of the scan, as these can interfere with the ultrasound gel.
What Happens During the Scan
During a head and neck ultrasound, you will typically lie on your back on an examination table. The sonographer will apply a clear, water-based gel to your neck, which helps sound waves travel effectively into your body. The sonographer then gently presses a small, handheld transducer against your skin, moving it across the area being examined. You may feel a slight pressure and a cool sensation from the gel, but the procedure is generally painless. The transducer emits sound waves that create images on a monitor, and the scan typically takes between 15 to 30 minutes.
Receiving Your Results
After your head and neck ultrasound is complete, a radiologist, a physician specializing in medical imaging, reviews and interprets the images. They generate a detailed report of the findings, which is sent to your referring healthcare provider. Results are typically available within a few days to a week. Your doctor will then schedule a follow-up appointment to discuss the ultrasound findings, including the diagnosis, any necessary next steps, and treatment plans.
