Systematic review and meta-analysis of the diagnostic accuracy of ultrasonography for deep vein thrombosis [PDF]

, 2005
Background Ultrasound (US) has largely replaced contrast venography as the definitive diagnostic test for deep vein thrombosis (DVT). We aimed to derive a definitive estimate of the diagnostic accuracy of US for clinically suspected DVT and identify ...

Angiogenic gene expression and vascular density are reflected in ultrasonographic features of synovitis in early Rheumatoid Arthritis: an observational study. [PDF]

, 2015
INTRODUCTION: Neovascularization contributes to the development of sustained synovial inflammation in the early stages of Rheumatoid Arthritis. Ultrasound (US) provides an indirect method of assessing synovial blood flow and has been shown to correlate ...

Comparison of clinical tests and doppler ultrasound in the preoperative assessment of lower extremity varicose veins

Indian Journal of Vascular and Endovascular Surgery, 2017
Introduction: Varicose vein of the lower extremity is a very common problem and is associated with severe morbidity if left untreated. Recurrence is inevitable if preoperative assessment of incompetence is not accurate.

Venous occlusion plethysmography vs. Doppler ultrasound in the assessment of leg blood flow kinetics during different intensities of calf exercise [PDF]

, 2017
PurposeIt has recently been shown that venous occlusion plethysmography (VOP) can successfully assess the rate of increase in leg blood flow (LBF) (LBF kinetics) responses during calf exercise, but there is lack of data supporting its validity ...

A phantom study on the applicability of a detectability index in ultrasound imaging

Frontiers in Physics
The assessment of clinical image quality on ultrasound is currently often subjective. While image quality factors such as contrast response or depth of penetration can be evaluated semi-automatically, the evaluation of high contrast resolution requires ...
