To accurately interpret ultrasonographic images, a working knowledge of ultrasonography physics, including ultrasound wave production, interaction of ultrasound waves with tissues, and ultrasonographic artifacts is necessary.1 Although many weekend short courses in ultrasonography instruction are available, these are brief introductions to ultrasonographic examinations and interpretation. Using a high-quality atlas4 and an anatomy text will help the successful ultrasonographer build skill in the examination. A focus on the production of diagnostic-quality images is essential. The wide availability of teleradiology consultation can aid in image interpretation.
