Ultrasound for Primary Care Practitioners and Emergency Medicine Physicians
Previous chapters have described in depth the anatomy, image acquisition techniques, and sonographic appearance of varying thyroid and parathyroid pathologies, though largely at the level of the expert or specialist. With point-of-care ultrasound training taking place in an ever increasing number of medical schools, residency programs, and clinical settings, it can be expected that an expanding number of nonspecialists will be performing thyroid ultrasonography, whether for teaching or clinical purposes. This chapter describes benefits and limitations of the compact and portable machines used in nonspecialty settings, highlights the basic views taught to clinicians for point-of-care ultrasound (POCUS), and outlines several clinical uses of thyroid ultrasound for primary, acute, and emergency care providers in a case-based format.

This brief clip demonstrates both the enlarged right thyroid lobe and the image quality attainable with very small handheld units. These are nevertheless exceptionally convenient and enhance patient assessment in a busy clinical office of a primary care physician or the emergency department (MP4 1669 kb)
In this brief clip captured with a handheld ultrasound machine innumerable hypoechogenic areas are noted with thyroid depth which requires no measurement to be determined increased (MP4 1667 kb)
