Objective: To discuss diagnostic value of color Doppler ultrasound for abnormal pregnancy and

Full-term infants with early-stage brain injuries from asphyxia were examined with two-dimensional ultrasound and color Doppler to assess the use of ultrasound in evaluating early brain injuries after neonatal asphyxia. The sonographic features of ultrasound and color Doppler were compared to those of magnetic resonance imaging (MRI). Ultrasound was used to monitor the brain parenchyma, lateral...

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...

PURPOSE The aim of this experimental study was to evaluate whether the acoustic radiation force (ARF) is a potential source of twinkling artifacts in color Doppler images. METHODS Color Doppler images were obtained using a clinical ultrasonic scanner (Voluson e, GE Healthcare) for a high contrast (+15 dB) circular scattering phantom at pulse repetition frequencies (PRFs) ranging from 0.1 to 1...

OBJECTIVE To evaluate the performance of color and bidirectional power Doppler ultrasound combined with Fetal Intelligent Navigation Echocardiography (FINE) in examining the fetal heart. METHODS A prospective cohort study was conducted of fetuses in the second and third trimesters with a normal heart or with congenital heart disease (CHD). One or more spatiotemporal image correlation (STIC) v...

PURPOSE Despite the routine use of helical CT in diagnosis of renal colic, there are recent concerns regarding the radiation exposure, overuse and costs. We attempted in this retrospective study to evaluate the accuracy of ultrasound (gray-scale and color Doppler with twinkling), KUB and urinalysis in diagnosis of renal colic due to ureteral calculi presented in Emergency Room. MATERIALS AND ...

Doppler ultrasound examination revealed signs of tendinosis with significant neovascularity, formed by immature tortuous and dilated vessels into intratendinous mass (Figure 1A). Furthermore, color Doppler scans showed areas of intratendinousedema in the proximal patellar-tendon interface (Figure 1A). After discussing the various treatment options, the patient opted to try etamsylate injection ...
