The Multi-Center Study of Shear Wave Elastography on Thyroid Nodules

2016-10-19 02:38:21 | BioPortfolio

Summary

The incidence rates of thyroid cancers have increased in the past decade. Additionally, up to 68% of people have thyroid nodules. Consequently, a precise evaluation of thyroid nodules is very important and can avoid unnecessary biopsy of benign nodules. Shear wave elastography(SWE), a novel ultrasound-based elastographic method, is a new real-time, quantitative, operator-independent, and reproducible technique. Briefly, shear wave elastography uses a radiation force produced by an ultrasonic beam to stress tissues and ultrafast sonographic tracking techniques to measure the speed of shear waves. Based on the Young modulus formula, tissue elasticity can be derived from the shear wave propagation speed, and a real-time color-coded elastogram can be displayed, showing softer tissue in blue and stiffer tissue in red.

There are lots of research confirmed that SWE has a certain value in the diagnosis of thyroid carcinoma. These studies include prospective studies and retrospective studies, but both belong to a single center study. It has not been applied to the study of the multicenter of thyroid disease.

The main purpose of the study is to assess the performance of SWE for identification of benign and malignant thyroid nodules and calculate the optimal cutoff value for each parameter in multicenter study; the secondary purpose is to evaluate the application value of SWE for uncertain nodules by FNA.

Medical and Biotech [MESH] Definitions

A small circumscribed mass in the THYROID GLAND that can be of neoplastic growth or non-neoplastic abnormality. It lacks a well-defined capsule or glandular architecture. Thyroid nodules are often benign but can be malignant. The growth of nodules can lead to a multinodular goiter (GOITER, NODULAR).

An enlarged THYROID GLAND containing multiple nodules (THYROID NODULE), usually resulting from recurrent thyroid HYPERPLASIA and involution over many years to produce the irregular enlargement. Multinodular goiters may be nontoxic or may induce THYROTOXICOSIS.

An aggressive THYROID GLAND malignancy which generally occurs in IODINE-deficient areas in people with previous thyroid pathology such as GOITER. It is associated with CELL DEDIFFERENTIATION of THYROID CARCINOMA (e.g., FOLLICULAR THYROID CARCINOMA; PAPILLARY THYROID CANCER). Typical initial presentation is a rapidly growing neck mass which upon metastasis is associated with DYSPHAGIA; NECK PAIN; bone pain; DYSPNEA; and NEUROLOGIC DEFICITS.

Autoantibodies that bind to the thyroid-stimulating hormone (TSH) receptor (RECEPTORS, THYROTROPIN) on thyroid epithelial cells. The autoantibodies mimic TSH causing an unregulated production of thyroid hormones characteristic of GRAVES DISEASE.

A condition characterized by the presence of rudimentary THYROID tissue at the base of the TONGUE. It is due to failed embryonic development and migration of thyroid tissue to its normal location. The lingual thyroid usually cannot maintain adequate hormone production thereby resulting in HYPOTHYROIDISM.
