The objective of this observational study was to evaluate the effect of transverse and longitudinal sections on the measurement of thyroid nodule stiffness by shear wave elastography. The main questions it aims to answer are: (i) to compare the diagnostic efficacy of different section orientations of shear wave elastography for the diagnosis of benign and malignant thyroid nodules; (ii) to analyze the correlation between the two orientations of transverse and longitudinal sections of shear wave elastography; and (iii) to compare the reliability and consistency of the two orientations of transverse and longitudinal sections of shear wave elastography for the diagnosis of thyroid nodules. Participants will undergo routine ultrasound examination of the thyroid gland and shear wave elastography, and the measured modulus of elasticity of the nodules in both transverse and longitudinal sections will be recorded.
There is no scientific data on post-thermal ablation cytological aspects, but treated nodules that grow back significantly after a procedure justify a new cytology in order not to ignore a neoplastic process. The EU-TIRADS classification usually used to stratify the risk of cancer (and to justify a fine needle aspiration biopsy) of thyroid nodules is not validated for nodules treated by thermal ablation (TA) (post-RF nodules). However, these nodules often acquire ultrasound criteria of suspicion making it necessary to develop an ultrasound stratification of the risk of malignancy specific to nodules treated by TA. The objective of this work is to describe the ultrasound and cytological aspects of these treated nodules by performing a systematic assessment at 3 years after thermal ablation including systematic neck ultrasound and fine needle aspiration biopsy. Thus, an ultrasound and cytological atlas (Bethesda classification 2017) of nodules treated by thermal ablation will be constituted.
The purpose of this observational research is to evaluate and compare clinical outcomes after treatment for symptomatic benign multinodular goiter (MNG) patients. This is a data collection study in which we ask participants to give access to information generated before and after treatment of their condition.
There is an epidemic of thyroid cancer that is harmful to patients and the medical system. The study hypothesizes that the use of an electronic conversation aid during clinical visits can help patients and clinicians collaborate when deciding the next step in management for a thyroid nodule. The study aims to update a conversation aid prototype that was developed to support shared decision making in the diagnosis of thyroid cancer.

The study hypothesizes that the use of an electronic conversation aid during clinical visits can help patients and clinicians collaborate. The study aims to update a conversation aid prototype that was developed to support shared decision making in the diagnosis of thyroid cancer and conduct a pilot clinical trial to evaluate the feasibility of conducting a larger efficacy study.
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.
When the DNA inside of human cells undergoes certain alterations (mutations), the cells may develop into a cancer. The cancer cells may shed this DNA into the blood stream. This circulating tumor DNA (ctDNA) can be detected by very sensitive, specialized laboratory tests. Measurement of ctDNA has been shown to be useful for following patients with known cancer. The purpose of this study is to examine blood specimens for the presence of ctDNA in individuals without known cancer who are scheduled to undergo a fine needle aspiration biopsy of the thyroid gland because of one or more thyroid nodules in order to see if the ctDNA test can detect a cancer at a very early stage. The results of this study should help define the role of ctDNA in the detection of early stage thyroid cancer and to define how sensitive it is (i.e. how well it picks up cancer when it is present) and how specific it is (i.e. how often is ctDNA found in patients with benign thyroid nodules).
Ideally randomized controlled trials should be carried out to compare the cost-effectiveness between FNAC and watchful waiting but such studies are very difficult to conduct in practice because they require following up very large number of subjects for a long period of time. The aims are to determine the health-related quality of life (HRQOL) and HRQOL preference (utility) of patients undergoing watchful observation (no FNAC) and routine FNAC, and to determine the cost-effectiveness of two strategies in managing small incidental thyroid nodules for the Chinese population in Hong Kong.
One of the major side effects of surgery to remove the thyroid gland is transient (lasting for a short time) low calcium levels in the blood, or "hypocalcemia." Low calcium levels can cause symptoms such as numbness around the mouth, tingling or cramping in the hands and feet, severe muscle spasms, inability to breathe, or heart rhythm (heart beat) abnormalities. Severe symptoms are life threatening, so it is important to start the management of these symptoms in the hospital. Treating low calcium levels sometimes require patients to spend a few extra days in the hospital. The human body needs vitamin D to function and stay healthy. Vitamin D helps the body get the calcium needed to make strong bones and teeth. The purpose of this study is to determine if taking vitamin D before surgery to remove the thyroid gland affects whether or not you may have low calcium levels after your surgery and to test the hypothesis that those who are given the Vitamin D before surgery will have decreased hypocalcemia and a shortened hospital stay.
