To begin, select a high frequency linear transducer of 10 megahertz. Set the ultrasound to B mode and use the highest frequency of the probe. Adjust the depth to three centimeters and gain 50%to 60%Position the patient in the supine position with the neck slightly extended, use a pillow to support the patient's head.
For transverse images, orient the probe with the marker pointing towards the patient's right side. For longitudinal scanning, orient the marker at the cephalic side. Apply gel to the probe surface.
Place the probe below the thyroid cartilage to scan the thyroid gland. Save the obtained images. connects the right and left lobes of the thyroid gland.
Consider the echogenicity of a normal thyroid gland as a reference. For any concomitant thyroid disease, compare the echogenicity to that of the surrounding muscles.
