Thyroid scintigraphy in diagnosis of nodular and diffuse thyroid pathology

Elastography: A New Ultrasound Technique in Nodular Thyroid Pathology

Elastography is a new technique for evaluating the stiffness of nodules. It is generally recognised that malignant thyroid lesions are harder than benign lesions. Different elastographic techniques are presented, with characteristics, advantages and limita‐ tions. Qualitative and semiquantitative methods are described. Comparison of the main existing techniques, static and dynamic elastographie...

Thyroid and parathyroid scintigraphy

Pitfalls in the diagnosis of thyroid dysgenesis by thyroid ultrasonography and scintigraphy.

OBJECTIVES We aimed to investigate the reliability of thyroid ultrasonography (US) and scintigraphy in determining the type of thyroid dysgenesis (TD). METHODS The study included 82 children (8.0±5.6 years) with a diagnosis of TD by thyroid scintigraphy with (99m)Tc and/or US. The patients were re-evaluated 6.0±5.1 years after the diagnosis. Thyroid US was performed in all cases, regardless o...

Thyroid Hormone Tutorial: Thyroid Pathology

Thyroid disorder is a general term representing several different diseases involving thyroid hormones and the thyroid gland. Thyroid disorders are commonly separated into two major categories, hyperthyroidism and hypothyroidism, depending on whether serum thyroid hormone levels (T4 and T3) are increased or decreased, respectively. Thyroid disease generally may be sub-classified based on etiolog...

Pendrin expression in nodular and non-nodular thyroid tissues.

INTRODUCTION Different mechanisms for the expression of pendrin which is an apical iodide transporter have been reported in nodular thyroid tissues compared to normal thyroid. The aim of the present study was to determine the alterations of pendrin expression in nodular and surrounding non-nodular thyroid tissues and clarify the role of pendrin in the functional behaviour of nodular lesions. ...
