The Point Of Care Ultrasound course in Neurology Unit 4 focuses on advanced methods of using ultrasound for neurovascular structures, including nerves' echogenicity changes in pathology. Clinical indications include assessing neurovascular bundles for neuralgia, brachial plexus injuries, and chronic headaches, with emphasis on anatomy and ultrasound protocols.

Exploration of advanced ultrasound methods for neurologists focusing on the neurovascular system, including clinical indications, anatomy, and ultrasound protocols. Detailed examination of nerve pathology, changes in echogenicity, and vascularity in conditions like neuralgia, brachial plexus injuries, and chronic headaches.

The chapter discusses the ultrasound evaluation of nerve pathology in patients with hereditary transthyretin amyloidosis, focusing on measurements of nerve diameter, echogenicity, and vascularity. It highlights the differences in nerve appearance between healthy and unhealthy sides, showcasing how ultrasound can aid in diagnosing nerve-related conditions.

The chapter discusses using ultrasound to identify neurovascular bundles such as the supraorbital and infraorbital nerves, as well as the brachial plexus and greater occipital nerve. It also covers distinguishing between healthy and unhealthy nerves using echogenicity and vascularity.
