A fine needle aspiration (FNA) biopsy is the standard procedure of choice for differentiating between benign and malignant thyroid nodules, and ∼300,000 thyroid FNA biopsies are performed in the U.S. each year. However, FNA is invasive, costly and uncomfortable for patients. Furthermore, a large percentage (∼70%) of these FNAs turn out to be benign. In this paper, we present a non-invasive and automatic...
The diagnosis for thyroid nodules is currently made via an FNA biopsy. It is estimated that somewhere between 250,000 and 300,000 thyroid FNA biopsies are performed in the United States annually. However, a large percentage (approximately 70%) of these biopsies turn out to be benign. The purpose of this study is to evaluate whether ultrasound elastography can be used as a screening tool to reduce...
For ultrasound thyroid elastography, hand-induced freehand compression is typically applied on the neck area to induce strain in the thyroid. In contrast to this conventional approach, we have utilized natural pulsation of the carotid artery as the compression source for thyroid elastography. We have developed strain processing techniques to aid interpretation of strain induced by internal compression...
