B-flow, a non-Doppler technology for flow mapping: early experience in the abdomen.
B-flow imaging is a non-Doppler technology for blood flow imaging that was introduced on high-frequency transducers at the end of the last decade. It has only recently become available on convex array and sector transducers suitable for abdominal examination. B-flow technology is not plagued by some of the troublesome pitfalls often encountered during color and power Doppler flow imaging, and appears promising as an adjunct to Doppler evaluation of blood flow in the abdomen. This article introduces the author's early experience using B-flow in the abdomen, and illustrates the potential advantages this technique offers relative to Doppler flow mapping.
