Doppler Ultrasound in Liver Diseases

The role of Doppler ultrasound in rheumatic diseases.

The use of Doppler techniques, including power, colour and spectral Doppler, has greatly increased in rheumatology in recent years. This is due to the ability of Doppler US (DUS) to detect pathological vascularization within joints and periarticular soft tissues, thereby demonstrating the presence of active inflammation, which has been reported to be correlated with the local neo-angiogenesis. ...

Carotid doppler ultrasound evaluation in patients with lichen planus

Background: Lichen planus is a chronic inflammatory disease associated with an increased risk of subclinical atherosclerosis and cardiovascular diseases. This study aimed to evaluate patients with lichen planus using carotid Doppler ultrasound parameters.Methods: Forty patients with lichen planus and 40 controls were included in this study. Common carotid...

Vascular complications after adult liver transplantation: Evaluation with Doppler ultrasound

Doppler ultrasound in renal transplantation.

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...

Transcranial Doppler ultrasound.

Transcranial Doppler ultrasound allows measurements of blood flow velocity to be made from the basal intracerebral vessels. The major advantages of transcranial Doppler ultrasound are that it is non-invasive, relatively cheap, can be performed with portable machines, allows monitoring for prolonged periods, and has a high temporal resolution making it ideal for studying dynamic cerebrovascular ...
