While most endocrinology offices offer 2D thyroid ultrasound, Wilmington Endocrinology utilizes 3D technology for our thyroid ultrasound exams.  The added dimension offers increased visibility, detection, and accuracy.

3DTHYROID® is a 3D technology that we utilize in our office to detect malignant thyroid nodules and to help with needle guidance during fine-needle aspiration biopsy.  3DTHYROID® technology uses 3D volume measurements that may provide more useful information about malignant thyroid lesions.

What is a thyroid ultrasound? 
An ultrasound is performed by sending out high frequency sound waves which pass through the body and are reflected back.  These echos are then analyzed and built into a picture of the body part that defines the shape, size, texture, and vascularity of a thyroid gland.

How is 3DTHYROID® different from 2D thyroid ultrasound?
The difference between 2D and 3D ultrasound can be compared to a loaf of bread.  A 2D image is like looking at one slice of bread, while a 3D image is like seeing the whole loaf – height and width as well as depth.

Is 3DTHYROID® more accurate?
In the case of a fine-needle aspiration biopsy, 3D ultrasound enables the physician to be sure the needle is inside the nodule, leading to fewer misdiagnosed and insufficient samples.
