An Experimental Study Using Laser Doppler Flowmetry
We used laser Doppler flowmetry (LDF) to measure flux in cortical bone fragments as a method of determining their vascular status and viability. In an experimental tibial osteotomy measurements of flux were made from specific cortical sites both before and after osteotomy. Flux levels fell rapidly in non-vascularised fragments and remained significantly reduced throughout the experiment. By con...
متن کاملNormal Echocardiographic Measurements in a Korean Population Study: Part II. Doppler and Tissue Doppler Imaging
BACKGROUND Hemodynamic and functional evaluation with Doppler and tissue Doppler study as a part of comprehensive echocardiography is essential but normal reference values have never been reported from Korean normal population especially according to age and sex. METHODS Using Normal echOcaRdiographic Measurements in a KoreAn popuLation study subjects, we obtained normal reference values for ...
متن کاملI-44: Color Doppler Imaging in Impotence
Sexual impotent is very common entity and define as inability to induce or maintaining penile erection during sexual intercourse. Studies reveals about 10% of men aged 40-70 years have complete, 17% have mild and 25% have moderate amount of erectile dysfunction. The sexual impotence has different etiology including psychogenic, neurogenic, arteriogenic and venogenic causes. Current studies reve...
متن کاملSonoelastography 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...
