Revealing Intraosseous Blood Flow in the Human Tibia With Ultrasound
JBMR Plus, 2021 Intraosseous blood circulation is thought to have a critical role in bone growth and remodeling, fracture healing, and bone disorders. However, it is rarely considered in clinical practice because of the absence of a suitable noninvasive in vivo ...

International Journal of Cardiology: Heart & Vasculature, 2014 Objectives: The main objective of this study was to assess the blood flow rate and velocity in coronary artery stenosis using intracoronary frequency domain optical coherence tomography (FD-OCT). A correlation between fractional flow reserve (FFR) and FD-

The Effects of Involuntary Respiratory Contractions on Cerebral Blood Flow during Maximal Apnoea in Trained Divers. [PDF]
PLoS ONE, 2013 The effects of involuntary respiratory contractions on the cerebral blood flow response to maximal apnoea is presently unclear. We hypothesised that while respiratory contractions may augment left ventricular stroke volume, cardiac output and ultimately ...

Abnormal Cerebrovascular Reactivity in Patients with Parkinson’s Disease
Parkinson's Disease, 2015 Background. Orthostatic hypotension (OH) is an important nonmotor manifestation of Parkinson’s disease (PD). Changes in cerebrovascular reactivity may contribute to this manifestation and can be monitored using transcranial Doppler. Objective.

Evaluation of arterial digital blood flow using Doppler ultrasonography in healthy dairy cows
BMC Veterinary Research, 2017 Background Local circulatory disturbances have been implicated in the development of foot disorders in cattle. The goals of this study were to evaluate the suitability of the interdigital artery in the pastern region in both hind limbs using pulsed-wave (
