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 ...

The application of 3D imaging in pediatric rheumatology helps to make the assessment of inflammatory changes more objective and to estimate accurately their volume and the actual response to treatment in the course of follow-up examinations. Additional interesting opportunities are opened up by the vascularity analysis with the help of power Doppler and color Doppler in 3D imaging. Contrast-enh...

While there has been wide general acceptance of Doppler methods that use the simplified Bernoulli relationship to estimate pressure gradients across stenotic orifices, there is still ongoing controversy related to potential sources of error in the method. In this study we tested accuracy of ultrasound Doppler measurements of flow velocity when compared with the gold standard of laser light Dopp...

INTRODUCTION An increasing number of studies have applied ultrasound to the evaluation of entheses in spondyloarthritis patients. However, no clear agreement exists on the definition of enthesitis, on the number and choice of entheses to examine and on ultrasound technique, which may all affect the results of the examination. The objectives of this study were to first determine the level of hom...

Two-dimensional viewing of three-dimensional anatomy by conventional ultrasound limits our ability to quantify and visualize a number of diseases and is partly responsible for the reported variability in diagnosis. Over the past two decades, many investigators have addressed this limitation by developing three-dimensional imaging techniques, including three-dimensional ultrasound imaging. In th...

Early detection and prompt treatment are important factors that limit morbidity and mortality secondary to venous air embolism (VAE) (1). The precordial Doppler ultrasonic sensor and transesophageal echocardiograph are the two most sensitive monitors currently available to detect VAE (2,3). The Aloka SSD-870 transesophageal echocardiograph is equipped with a Doppler sensor at the distal end of ...

resistive and pulsatility index (RI, PI ). Both are equally Introduction as useful although the RI is probably more commonly used. An RI <0.7 is normal, >0.9 abnormal, and Colour Doppler ultrasound facilitates not only a global between there is a large grey area. A PI <1.5 is assessment of the intrarenal vasculature but can also normal, and >1.8 abnormal. The higher the RI or PI be targetted to...
