The occurrence of thyroid nodules increases with age [1]. In geographical areas with a normal iodine intake, approximately 10% of the population develops a palpable thyroid nodule. This proportion increases in areas with insufficient iodine intake. Non-palpable thyroid nodules are usually diagnosed by a neck echography carried out for various reasons and are 5-10 folds more common than palpable...

Presently, one of the main issues to create challenges in medicine sciences by developing technology is the disease diagnosis with high accuracy. An automatic system is developed that classifies the thyroid nodule images using machine learning algorithms. Ultrasound imaging is the best way to prediction of which type of thyroid is there. Ultrasound thyroid Nodules images were distinguishing in ...

The National Cancer Institute (NCI) sponsored the NCI Thyroid Fine-Needle Aspiration (FNA) State of the Science Conference on October 22-23, 2007 in Bethesda, MD. The 2-day meeting was accompanied by a permanent informational website and several on-line discussions between May 1 and December 15, 2007 (http://thyroidfna.cancer.gov). This document summarizes the indications for performing an FNA ...

BACKGROUND Agenesis of the isthmus associated with nontoxic solitary nodular goiter is a rare congenital anomaly. Imaging data exceptionally has been previously reported in the English language literature. CASE PRESENTATION Preoperative assessment of a 22-year-old white man patient showed an asymptomatic nodule of the thyroid at the left lobe, measuring 2.3 x 1.5 cm in diameter without region...

110 patients with thyroid nodules were examined by ultrasound during the period from April 1981 to June 1983. All patients had thyroid isotope scans which showed cold nodules. Subsequent surgery was performed in each case and histology of the lesions identified. Prior to the introduction of ultrasound the only useful preoperative diagnosis was made by thyroid scintiscanning." The present study ...

Diagnostic imaging is an important tool in medical science due to the constrained observations of the expert and uncertainties in medical knowledge. A thyroid ultrasound is a non-invasive imaging study used to detect and classify abnormalities of the thyroid gland. Computerized system is a valuable and beneficial means for feature extraction and classification of thyroid nodule in order to elim...

OBJECTIVE Primary hyperparathyroidism (PHPT) is often seen in conjunction with an underlying thyroid disorder. Imaging methods that are used to localize the parathyroid adenoma also detect associated thyroid nodules and thyroid cancer. The aim of this study was to detect the rate of thyroid cancer identified while performing parathyroidectomy and thyroidectomy in patients with PHPT. MATERIAL ...

Ultrasonography (US) features of thyroid nodules can be helpful in identifying those most at risk for malignancy; these include marked hypoechogenicity, microcalcifications, irregular margins, and a taller-than-wide shape (nonparallel orientation). Some cystic change morphologically after simple aspiration percutaneous ethanol injection treatment. They show hypoechogenicity margins on the US di...

INTRODUCTION Ultrasound is the most frequently used imaging method to evaluate thyroid nodules. Sonographic characteristics of thyroid nodules which are concerning for malignancy are important to define the need for fine needle aspiration biopsy or open surgery. OBJECTIVE To evaluate malignancy risk of solid thyroid nodules through sonographic scoring. The effects of nodule size ≥2cm and asso...

A thyroid nodule is a very common condition which can be found among 40 to 50% of general population on ultrasound. Identification of thyroid cancer cells through fine needle aspiration (FNA) is a gold standard for diagnosis of thyroid cancer. Among all thyroid nodules, thyroid cancer occupied five to ten percent, and thus a large number of patients, even with benign thyroid nodules, are recomm...
