The Utility of Color-Flow Doppler Sonography in the Evaluation of Hyperthyroidism

Abstract

As with all facets of medicine, the key to uncovering the etiology of an illness lies in performing a careful history and physical examination. Such is also the case when dealing with patients who manifest with hyperthyroidism. Aside from the clinical encounter, physicians have a myriad of diagnostic tools at their disposal. A host of investigations, ranging from a simple blood test to a nuclear thyroid uptake and scan, can be ordered. In recent years, thyroid ultrasonography has established itself as a useful and popular medium for the evaluation of various forms of thyroid dysfunction. One aspect of performing a thyroid ultrasound involves assessing the intra thyroidal blood flow using color-flow Doppler sonography (CFDS).This editorial explores the utility and appropriate use of CFDS in the management of patients with hyperthyroidism.
