Power Doppler ultrasound-guided sialography using the phenomenon of increased blood flow: A technical report

Color Doppler ultrasound evaluation of testicular blood flow in stallions.

The objectives of this study were to evaluate the potential use of color Doppler ultrasound to characterize blood flow to the stallion testis, and to establish reference values for Doppler measures of blood flow in the testicular artery of the stallion. Both testes from each of 52 horses were examined using a pulsed-wave color Doppler ultrasound with a sector array 5/7.5 MHz transducer with a 1...

Evaluation of fetal cerebral blood flow perfusion using power Doppler ultrasound angiography (3D-PDA) in growth-restricted fetuses

OBJECTIVE to explore the potential of 3D Power Doppler Angiography (3D PDA) to evaluate the cerebral circulation in normal and growth restricted fetuses (IUGR). STUDY DESIGN in a pilot study, we enrolled 51 appropriate for gestational age (AGA) pregnancies and 17 singleton pregnancies presenting IUGR, all between 22 and 38 weeks of gestation. Using 3D power Doppler ultrasound, a -volume acqui...

Doppler Ultrasound Blood Flow Measurement System for Assessing Coronary Revascularization

This work describes a Doppler ultrasound system for measuring blood flow. The system is intended to be used for assessing coronary implants and bypass operations. Quantifying the blood flow through these implants/bypasses is an important task to ensure the chirurgical process, thus, reducing both the post-chirurgical and death risks. The system is based on an open architecture that is portable ...

Ultrasound- guided Hydrostatic (Hydrocolonic) Treatment of Meconium Ileus: A Preliminary Report

Background Meconium ileus (MI) is one type intestinal obstruction due to inspissated meconium at the level of the terminal ileum. The purpose of this study is to present the non-ionizing ultrasound-guided approach for the treatment of meconium ileus. Materials and Methods This study was performed, prospectively, at Dr. Sheikh and Akbar children's Hospitals, Mashhad University of Medical Science...
