Pulsed Doppler: Diameter, Blood Flow Velocity
Diameter, blood flow velocity and volumic flow of the brachial artery were measured in 36 patients with sustained essential hypertension and compared with 25 normal subjects. Both hypertensives and control subjects were classified according to age into those younger than and those older than 40 years. For the determinations, a pulsed Doppler velocimeter with an adjustable range-gated time syste...

متن کاملTransvaginal ultrasonography combined with color velocity imaging and pulsed Doppler to detect residual trophoblastic tissue.
The value of transvaginal B-mode ultrasonography combined with color velocity imaging and pulsed Doppler to detect retained trophoblastic tissue was evaluated prospectively in a series of 40 patients with postpartum (n = 15) or postabortion (n = 25) bleeding. Color velocity imaging was used to identify color-coded blood flow signals within myometrium and/or endometrium. Flow was subjectively qu...
متن کاملMyocardial Tissue Doppler Velocity in Child Growth
BACKGROUND In adults, tissue Doppler imaging (TDI) is a recommended component of routine echocardiography. However, TDI velocities are less accepted in pediatrics, due to their strong variability and age dependence in children. This study examines the distribution of myocardial tissue Doppler velocities in healthy children to assess the effect of age with cardiac growth on the various echocardi...
متن کامل[Assessment of left atrial wall velocities by pulsed wave tissue Doppler imaging. A new approach to the study of atrial function].
INTRODUCTION AND OBJECTIVES To analyze the profile of left atrial wall velocities by pulsed wave tissue Doppler imaging, and to compare the relationship between these observations and the transmitral and pulmonary vein flow velocities obtained by conventional pulsed Doppler echocardiography. PATIENTS AND METHOD We studied 90 patients (50 women and 40 men, mean age 48 [22] years). Pulsed tissu...
