The influence of the hematocrit level in dogs and cats on the presentability and accuracy of the blood flow visualization

Purpose: It is to be assumed, that beside the parameters like angulation, velocity and vessel size the appearance of the ultrasound image is also influenced by the number of reflectors. If this hypothesis is true, the diagnostic evaluation might be influenced in anemic patients. Materials and methods: The presentability and accuracy of the blood flow detection was analyzed on different flow phantoms also comparing CDI, PDI and B-Flow®. The influence of the hematocrit level on the presentability and accuracy of the blood flow visualization was examined under standardized conditions. The flow phantoms consists of…
