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-

Transcutaneous measurement of blood velocity profiles and flow [PDF]
Cardiovascular Research, 1973 A comprehensive report is presented of the application of a pulsed ultrasound Doppler velocity meter for transcutaneous measurement of time varying velocity, velocity profiles, and instantaneous flow in arteries of anaesthetized dogs. The procedure used to provide direct velocity and flow calibration using the Doppler equation is outlined.

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 ...

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.

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 ...

Quantification of leptomeningeal collateral blood flow in hypertensive rats during ischemic stroke
Journal of Stroke and Cerebrovascular DiseasesObjectives: There is increasing evidence that poor leptomeningeal collateral blood flow in hypertensive animals is due to increased vascular myogenic tone, indicating that therapies to enhance collateral blood flow during ischemic stroke may be ...
