Abstract

Currently, there is little understanding of the role of echogenic needles and beam steering at moderate angles of needle insertion. The ultrasound images of the echogenic and nonechogenic needles inserted into pork at 40 degrees, 50 degrees, and 60 degrees were scored by anesthesiologists on a scale of 0-10. The effect of different levels of beam steer was also explored. At 40 degrees, steep beam steering improves visualization of both nonechogenic and echogenic needles to an equal, satisfactory level. At 50 degrees and 60 degrees, visualization of nonechogenic needles is poor, whereas visibility of an echogenic needle was adequate and may be improved with steep beam steering.
