A Preliminary Study of Quantitative Ultrasound for Cancer-Risk Assessment of Thyroid Nodules.

Front Endocrinol (Lausanne) 2021 19;12:627698. Epub 2021 May 19.

Section of Endocrinology, Diabetes and Nutrition, Boston Medical Center, Boston University School of Medicine, Boston, MA, United States.

Background: Gray-scale, B-mode ultrasound (US) imaging is part of the standard clinical procedure for evaluating thyroid nodules (TNs). It is limited by its instrument- and operator-dependence and inter-observer variability. In addition, the accepted high-risk B-mode US TN features are more specific for detecting classic papillary thyroid cancer rather than the follicular variant of papillary thyroid cancer or follicular thyroid cancer.

Ultrasound Image Classification of Thyroid Nodules Using Machine Learning Techniques.

Medicina (Kaunas) 2021 May 24;57(6). Epub 2021 May 24.

School of Medicine, College of Medicine Nursing and Health Sciences, National University of Ireland Galway, H91 TK33 Galway, Ireland.

: Thyroid nodules are lumps of solid or liquid-filled tumors that form inside the thyroid gland, which can be malignant or benign. Our aim was to test whether the described features of the Thyroid Imaging Reporting and Data System (TI-RADS) could improve radiologists' decision making when integrated into a computer system. In this study, we developed a computer-aided diagnosis system integrated into multiple-instance learning (MIL) that would focus on benign-malignant classification. Read More

Incidental Thyroid Nodules on Imaging: Relevance and Management.

Radiol Clin North Am 2021 Jul;59(4):525-533

Department of Radiology, University of Alabama at Birmingham, 619 19th Street South, GSB 409, Birmingham, AL 35249, USA.

Incidental thyroid nodules (ITNs) are commonly detected on imaging examinations performed for other reasons, particularly computed tomography (CT) (and now PET-CT and even PET-MR imaging), MR imaging, and sonography, primarily a consequence of the increasing sensitivity of these diagnostic modalities. Appropriate management of ITNs is crucial to avoid the cost and medical consequences of unnecessary workups. Read More

Role of elastography strain ratio and TIRADS score in predicting malignant thyroid nodule.

Arch Endocrinol Metab 2021 May;64(6):735-742

Kasr Al-Aini Hospitals, Cairo University, Cairo, Egypt,

Objective: Ultrasonography (US) is the most accurate and cost-effective imaging method in diagnosis of thyroid nodules. A practical thyroid imaging reporting and data system (TIRADS) for thyroid nodules has been proposed to classify nodules of the thyroid gland to solve the problem of nodule selection for fine needle aspiration cytology (FNAC). Real-time elastography and strain ratio (SR) is a method used to assess the stiffness and predict the malignancy of thyroid nodules. Read More

Papillary thyroid microcarcinoma: is active surveillance always enough?

Clin Endocrinol (Oxf) 2021 May 21. Epub 2021 May 21.

Department of Endocrinology and Diabetes, Royal North Shore Hospital Sydney, Australia.

The incidence of papillary thyroid carcinoma (PTC) has increased over recent decades. This apparent epidemic has been attributed to the overdiagnosis of small PTC ≤ 10mm in diameter (PTMC) incidentally detected on imaging for unrelated presentations. While most PTMC follow an indolent disease course, there is a small but significant proportion of cases that display more biologically aggressive features such as early metastasis and lymph node involvement.

Thyroid "claw sign" a useful diagnostic marker in the outsized lesions of isthmus: A large colloid cyst.

Radiol Case Rep 2021 Jul 30;16(7):1688-1694. Epub 2021 Apr 30.

Department of Orthopedics, Jarir Medical Centre, Riyadh, Saudi Arabia.

Thyroid isthmus lesions are generally small sized and can be solid or cystic. Discerning isthmic origin of a large nodule, especially if purely cystic, can become a diagnostic challenge because of thin thyroid tissue in it. We report a case of a 68-year-old male patient who had 6 weeks history of non- inflammatory central neck swelling associated with recent dysphagia, for which he underwent ultrasound and computed tomography (CT) scan examinations.

Testing telediagnostic thyroid ultrasound in Peru: a new horizon in expanding access to imaging in rural and underserved areas.

J Endocrinol Invest 2021 May 10. Epub 2021 May 10.

Pontifica Universidad Catolica del Peru, Av. Universitaria 1801, 15088, San Miguel, Peru.

Purpose: Thyroid ultrasound is a key tool in the evaluation of the thyroid, but billions of people around the world lack access to ultrasound imaging. In this study, we tested an asynchronous telediagnostic ultrasound system operated by individuals without prior ultrasound training which may be used to effectively evaluate the thyroid and improve access to imaging worldwide.

Methods: The telediagnostic system in this study utilizes volume sweep imaging (VSI), an imaging technique in which the operator scans the target region with simple sweeps of the ultrasound probe based on external body landmarks. Read More

Ultrasound features of medullary thyroid cancer as predictors of biological behavior.

Cancer Imaging 2021 Apr 9;21(1):33. Epub 2021 Apr 9.

Departments of Thyroid and Neck Tumor, Tianjin Medical University Cancer Institute and Hospital, National Clinical Research Center for Cancer, Key Laboratory of Cancer Prevention and Therapy, Tianjin, Tianjin's Clinical Research Center for Cancer, Tianjin, 300060, P. R. China.
