Low-Velocity Flow Doppler Enhancement for the Study of Spontaneous Echo Contrasts
Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2022 Detection of spontaneous echo contrasts (SEC) is important in assessing the risk of stroke and thromboembolism. Transthoracic echocardiography is the most widely used primary imaging for left ventricular SEC.

Reliability of EEG Interactions Differs between Measures and Is Specific for Neurological Diseases
Frontiers in Human Neuroscience, 2017 Alterations of interaction (connectivity) of the EEG reflect pathological processes in patients with neurologic disorders. Nevertheless, it is questionable whether these patterns are reliable over time in different measures of interaction and whether ...

Tissue Doppler in critical illness [PDF]
Critical Care, 2007 We applaud Sturgess et al (1) for their report on tissue Doppler imaging (TDI) in critical illness. Although their patients were selected and TTE performed at variable times after ICU admission, they provide a glimpse into the use of TDI and have generated many hypotheses.

Hearing the Hidden Agenda: The Ethnographic Investigation of Procedure [PDF]
, 1988 Laser Doppler flowmetry (LDF) is virtually the only non-invasive technique, except for other laser speckle based techniques, that enables estimation of the microcirculatory blood flow. The technique was introduced into the field of biomedical engineering

Echocardiography during submaximal isometric exercise in children with repaired coarctation of the aorta compared with controls [PDF]
, 2019 Objective Patients with repaired coarctation (RCoA) remain at higher risk of cardiac dysfunction, initially often only detected during exercise. In this study, haemodynamics of isometric handgrip (HG) and bicycle ergometry (BE) were compared in patients ...

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 ...
