Normal Doppler Reference Values of the Pericallosal Artery

Doppler ultrasonography of the fetoplacental circulation--normal reference values.

Normal reference values for the resistance index, A/B ratio and pulsatility index of the umbilical artery obtained by Doppler ultrasonography are presented. The resistance index and A/B ratio values are very similar to those previously published, indicating no need to formulate normal values for different populations. The pulsatility index differed from other published values, probably reflecti...

Doppler Echocardiographic Reference Values in Healthy

Introduction Doppler echocardiography provides a means to non-invasively evaluate the anatomy and function of the heart, and is playing an increasingly important role in the evaluation and management of patients or animals with all forms of cardiac disease [13]. It has now become a routine for the diagnosis and evaluation of heart disease in veterinary medicine [4]. This is especially true in l...

Normal Reference Values for Doppler Echocardiography: Influences of Ageing, Gender and Ethnicity

Echocardiography is now considered a standard diagnostic tool that enables the noninvasive quantification of cardiac chamber size, ventricular mass, and systolic function in various clinical situations. Technological progress in Doppler echocardiography has enabled the provision of hemodynamic information and the assessment of valvular heart disease and ventricular diastolic function. When inte...

Reference values from M-mode and Doppler echocardiography for normal Syrian hamsters.

AIMS Echocardiography has recently been introduced to small animal research, allowing serial measurements of cardiac diseases. In addition, the hamster model has been increasingly used, as it mimics many human heart conditions. However, no reference range of echocardiographic values reflecting normal left ventricular (LV) function exists for hamsters. The purpose of this study was to provide on...
