Pulsation-Induced Thyroid Strain Imaging

Principal Investigator: Yongmin Kim

Thyroid nodules are swellings that develop on the thyroid gland. Often they are benign, but in some cases they are cancerous. Making this distinction is important because 19-36% of the general population has thyroid nodules and it is estimated that more than 18 million people in the United States are affected. Finger palpitation and gray-scale ultrasound imaging are currently used to detect thyroid nodules but fall short in determining malignancy. Malignancy is determined using fine needle aspiration which is an invasive and uncomfortable procedure. Ultrasound images offer an alternate method for determining malignancy, but efforts are complicated because of arterial pulsation.

Researchers at the UW have developed a pulsation-induced thyroid strain imaging system which may help characterize thyroid tissue. This system is capable of producing high quality and repeatable strain images of tissues affected by arterial pulsation.

Pulsation-induced thyroid strain imaging is a promising technique that can provide a noninvasive method of acquiring information on tissue mechanical properties and aiding in the diagnosis of thyroid nodules. In addition, this technique may be applied to other tissues under the influence of arterial pulsation.
