Purpose To estimate the inter-observer reliability and agreement of offline analyses of three different ultrasound techniques for assessing tubal patency. Methods 100 tubes (n = 100) in 50 women were evaluated for tubal patency between November 2013 and July 2015 using ultrasound as index tests and laparoscopy as the reference standard. Three different ultrasound techniques were applied: two-dimensional grayscale ultrasound using air + saline as the contrast media (2D-HyCoSy); two- and three-dimensional grayscale ultrasound using foam as the contrast media (2 D/3D-HyFoSy); and the same technique but adding bi-directional power Doppler (2 D/3D-Doppler-HyFoSy)...

A 66-year-old man with poorly controlled type 2 diabetes was admitted for acute bilateral calf pain in the context of coronary artery disease, chronic renal failure, and peripheral neuropathy. Lower-extremity Doppler ultrasound excluded deep vein thrombosis. FDG-PET was performed to exclude a suspected infection because of elevated white blood cells and inflammatory markers but normal creatinine kinase levels. PET scan demonstrated intense bilateral calf muscle and left thigh muscle uptake, which in combination with the patient's history was consistent with diabetic myonecrosis, a rare end-stage complication of diabetes...

Cerebral autoregulation (CA) maintains cerebral blood flow (CBF) in the presence of systemic blood pressure changes. Brain injury can cause loss of CA and resulting dysregulation of CBF, and the degree of CA impairment is a functional indicator of cerebral tissue health. Here, we demonstrate a new approach to noninvasively estimate cerebral autoregulation in healthy adult volunteers. The approach employs pulsatile CBF measurements obtained using high-speed diffuse correlation spectroscopy (DCS). Rapid thigh-cuff deflation initiates a chain of responses that permits estimation of rates of dynamic autoregulation in the cerebral microvasculature...

Pulmonary hypertension (PH) is a disease with severe morbidity and mortality. Echocardiography plays an essential role in the screening of PH. The quality of the acquired continuous wave Doppler signal is the major limitation of the method and can greatly affect the accuracy of estimated pulmonary pressures. The aim of this study was to evaluate the clinical need to image from multiple ultrasound windows in patients with suspected pulmonary hypertension. We prospectively evaluated 65 patients (43% male, mean age 67...

Growing evidence suggests that increased intracranial pulsatility is associated with cerebral small vessel disease (SVD). We systematically reviewed papers that assessed intracranial pulsatility in subjects with SVD. We included 27 cross-sectional studies (n=3356): 20 used Doppler ultrasound and 7 used phase-contrast MRI. Most studies measured pulsatility in the internal carotid or middle cerebral arteries (ICA, MCA), whereas few assessed veins or cerebrospinal fluid (CSF). Methods to reduce bias and risk factor adjustment were poorly reported...

INTRODUCTION: Intubation is a frequently performed procedure in emergency medicine that is associated with significant morbidity and mortality when unrecognized esophageal intubation occurs. However, it may be difficult to visualize the endotracheal tube (ETT) in some patients. This study assessed whether the addition of color Doppler was able to improve the ability to visualize the ETT location. METHODS: This study was performed in a cadaver lab using three different cadavers chosen to represent varying neck circumference...

The cerebral hypoperfusion caused by chronic progressive stenosis or occlusion of intracranial arteries in moyamoya disease can be treated by direct bypass or indirect revascularization procedures. The extent of collaterals from the external carotid artery (ECA) after indirect revascularization surgery is the key point of angiographic follow-up, and the invasiveness of angiography impelled us to investigate the role of ultrasonography in the evaluation of collaterals. We hypothesized that the collaterals shown on angiography might produce corresponding hemodynamic changes in color Doppler ultrasonography...
