Sonoelastography using Compensated Power Doppler
Sonoelastography is the visualisation of elastic properties using ultrasound. It can enable tumours to be detected and localised based on their elasticity when they are less elastic than the surrounding soft tissue. In vibration sonoelastography the target tissues are vibrated while simultaneously recording ultrasound images. A technique for imaging relative elastic properties is proposed that ...
متن کاملKidney biopsy and power Doppler imaging.
BACKGROUND Practically, all complications of kidney biopsy are connected with hemorrhage. In the last years, the use of color Doppler sonography in monitoring kidney biopsies was being described, later the possibility of using power Doppler (PD) in performing kidney biopsies was presented. PD depicts the amplitude, or power, of Doppler signals rather than the frequency shift. This allows detect...
متن کاملrenal power doppler ultrasonographic evaluation of children with acute pyelonephritis
urinary tract infections are common in children. the available gold standard method for diagnosis, tc-99m dimercaptosuccinic acid scan is expensive and exposes patients to considerable amount of radiation. this study was performed to compare and assess the efficacy of power doppler ultrasound versus tc-99m dmsa scan for diagnosis of acute pyelonephritis. a quasi experimental study was conducted...
متن کاملThree-dimensional Power Doppler Ultrasonographic Evaluation of Induced Cystitis in Dogs
Objectives: The aim of this study was to investigate if three-dimensional power Doppler (3DPD) ultrasound (US) can detect bacterial cystitis in dogs better than two-dimensional (2D) US. Animals: Six mixed breed dogs Procedures: Ten ml of 0.1% alcoholic solution of salicylic acid was entered into the urinary bladder of six male mixed-breed dogs by catheter. Twenty four hours later, culture sol...
متن کاملUltrasound imaging for the rheumatologist. XVII. Role of colour Doppler and power Doppler.
The use of Doppler ultrasound in rheumatology has grown in recent years. This is partly due to the increasing number of rheumatologists who perform US in their daily clinical practise and also to the technological advances of US systems. Both colour Doppler and power Doppler are used to evaluate the degree of intra- and peri-articular soft tissue inflammation. Moreover, Doppler US has been foun...
