Ultrasound imaging is one of the most common visualizing tools used by radiologists to identify the location of thyroid nodules. However, visual assessment of nodules is difficult and often affected by inter- and intra-observer variabilities. Thus, a computer-aided diagnosis (CAD) system can be helpful to cross-verify the severity of nodules. This paper proposes a new CAD system to characterize thyroid nodules using optimized multi-level elongated quinary patterns. In this study, higher order spectral (HOS) entropy features extracted from these patterns appropriately distinguished benign and malignant nodules under particle swarm optimization (PSO) and support vector machine (SVM) frameworks...

BACKGROUND: Thermal ablation of thyroid nodules has gained momentum due to the possibility to avoid surgery. High-intensity focused ultrasound (HIFU) allows thermal treatment by energy ultrasound beam inside the targeted zone. Aim of our study was to evaluate the effects of HIFU treatment using Beamotion mode without anesthesia. METHODS: Since 2016, patients with normal thyroid function, benign thyroid nodules with diameter no larger than 4 cm, and presenting local discomfort and/or compressive symptoms were treated by HIFU...

BACKGROUND AND PURPOSE: Ultrasound is a standard technique to detect lymph node metastasis in papillary thyroid cancer. Cystic changes and microcalcifications are the most specific features of metastasis, but with low sensitivity. This prospective study compared the diagnostic accuracy of a predictive model for sonographic evaluation of lymph nodes relative to the radiologist's standard assessment in detecting papillary thyroid cancer metastasis in patients after thyroidectomy. MATERIALS AND METHODS: Cervical lymph node sonographic images were reported by a radiologist (R method) per standard practice...

The 2017 edition of the WHO book on Classification of Tumours of Endocrine Organs includes a new section entitled "Other encapsulated follicular-patterned thyroid tumours", in which the newly created NIFTP (Non-invasive follicular thyroid neoplasm with papillary-like nuclear features) is identified and detailed described. Despite deleting the word "carcinoma" from its name, NIFTP is not a benign tumor either, and is best regarded as a neoplasm with "very low malignant potential"...

The H-scan analysis of ultrasound images is a matched-filter approach derived from analysis of scattering from incident pulses in the form of Gaussian-weighted Hermite polynomial functions. This framework is applied in a preliminary study of thyroid lesions to examine the H-scan outputs for three categories: normal thyroid, benign lesions, and cancerous lesions within a total group size of 46 patients. In addition, phantoms comprised of spherical scatterers are analyzed to establish independent reference values for comparison...

Thyroid malignancies comprise only 2 per cent of all cancers. Yet the incidence of thyroid cancers has been increasing faster than other malignancies, likely due to increased screening and surveillance of thyroid nodules. The Bethesda system represents the preferred method of evaluating thyroid nodules for malignancy using fine needle aspiration (FNA). Many thyroidectomies are performed for small, asymptomatic nodules found on ultrasound. These small papillary cancers (<0.5 cm) are termed microcarcinomas and represent a more indolent natural history causing some to name them "occult papillary tumors...
