Malignant thyroid lesion Classification Biology essay
Thyroid nodules are a common clinical dilemma, but the vast majority are benign. The clinical importance of thyroid nodules rests on the need to detect thyroid cancer, which occurs in -10. The risk depends on factors such as age, gender, history of radiation exposure, and family history 1, 2. Citation, DOI, Disclosures, and Article Details. Ultrasound is the first-line imaging modality for the assessment of thyroid nodules found on clinical examination or incidentally on another imaging modality. This article is a review of sonographic features of thyroid nodules, which are used to determine the need for a fine needle biopsy. 1 Introduction. Thyroid nodules are cystic or solid nodules that are usually asymptomatic. Nevertheless, large thyroid nodules have also been shown to disrupt the normal functioning of cardiovascular and respiratory functions 1, 2. Pathologically, thyroid nodules are dichotomized into benign and malignant nodules. The fifth edition of the World Health Organization (WHO) Histological Classification of Thyroid Neoplasms released includes newly recognized tumor types, subtypes and a grading system. In this work, we present a Computer Aided Diagnosis-based CAD technique for automatic classification of benign and malignant thyroid lesions D using contrast-enhanced ultrasound images. The images were obtained from patients. Fine needle aspiration biopsy and histology confirmed the malignancy. Discrete Wavelet, Fine Needle Aspiration FNA remains the most accurate and cost-effective method to stratify patients with thyroid tumors based on their risk of malignancy ROM, 12, 13. Recently, the new Bethesda System for Reporting Thyroid Cytopathology TBSRTC was released, based on the new entities and terminology included in the Family History of Thyroid Cancer. age lt, gt male gt, pathology classification. Thyroid malignancies can be divided into the following major subtypes: primary thyroid cancer papillary thyroid carcinoma: 60-80 carcinomas. follicular thyroid carcinoma: 10-20. medullary thyroid carcinoma: 5.
