경부혈관 초음파 표준검사지침. 1부 - 기본 원리 및 표준검사 방법

Abstract

Use of ultrasound is safe in humans, and has been widely used in medical applications. B-mode sonography produces cross-sectional images and Doppler sonography measures blood flow velocities. Carotid duplex ultrasonography (CDU) has been mainly utilized in cerebrovascular disease. Recently, its use has been expanded in Parkinson's disease and neuromuscular disease as well as pain management. Point-of-care ultrasound is used in emergency and intensive care settings, and has the advantage of short examination time, relatively low cost, and reproducibility. However, the results may vary depending on the examiner’s skill. Therefore, a standard protocol for examination is needed. This practice guideline discusses basic principles, artifacts, and standard techniques, and thus can improve understanding of CDU for neck vessels.
