摘要:

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.

摘要:

Renal transplantation is the best treatment option for chronic renal failure, with marked improvement in social activity, work, and family life. In addition to these obvious improvements, it is an extremely cost-effective procedure when successful. Ultrasonography plays a major role in the imaging of these patients, and ultrasound (including color Doppler) is helpful to the transplant physician in detecting graft dysfunction and peritransplant collections, some of which may be drained under ultrasound guidance. It is also helpful in the diagnosis of chronic vascular complications including transplant artery stenosis and arteriovenous fistula. It has no specific application in the diagnosis of chronic rejection.

摘要:

The current literature reflects controversy regarding the accuracy of Doppler ultrasound for the detection of transjugular intrahepatic portosystemic shunt (TIPS) malfunction. Experience has revealed many pitfalls and artifacts that can potentially interfere with the proper performance and interpretation of Doppler studies in patients with TIPS. In this article the author discusses and illustrates the spectrum of pitfalls that may be encountered during Doppler evaluation of TIPS function.
