Preliminary Experience with Digital Subtraction Angiography in Cardiac Evaluation [PDF]
, 1985 iVe report our initial experience using digital subtraction angiography (DSA) techniques for cardiac evaluation. DSA of the heart may be performed with intravenous or right atrial injection of contrast medium (IVDSA) and with left ventricular or aortic ...

Evaluation of the Extension of the Cerebral Blood Flow and its Main Parameters [PDF]
arXiv, 1999 Among the major factors controlling the cerebral blood flow (CBF) - cerebral perfusion pressure, arterial partial pressure of oxygen (PaO2), cerebral metabolism, arterial partial pressure of carbon dioxide (PaCO2), and cardiac output, the effect of PaCO2 is peculiar in being independent of autoregulatory CBF mechanisms and it allows to explore the full

Aqueductal developmental venous anomaly as an unusual cause of congenital hydrocephalus: a case report and review of the literature [PDF]
, 2012 Introduction Aqueductal stenosis may be caused by a number of etiologies including congenital stenosis, tumor, inflammation, and, very rarely, vascular malformation.

Oxygenation and Blood Volume Periodic Waveforms in the Brain [PDF]
arXiv, 2011 Results of an experiment are presented whose aim is to explore the relationship between respiration and cerebral oxygenation. Measurements of end tidal CO2 (EtCO2) were taken simultaneously with cerebral oxygen saturation (rSO2) using the INVOS Cerebral Oximeter of Somanetics.

Normative Cerebral Perfusion Across the Lifespan [PDF]
arXivCerebral perfusion plays a crucial role in maintaining brain function and is tightly coupled with neuronal activity. While previous studies have examined cerebral perfusion trajectories across development and aging, precise characterization of its lifespan dynamics has been limited by small sample sizes and methodological inconsistencies. In this study,

Simple exercises that significantly increase cerebral blood flow and cerebral oxygenation [PDF]
arXiv, 2011 We tested the hypothesis that simple exercises may significantly increase cerebral blood flow (CBF) and/or cerebral oxygenation. Eighteen subjects ranging in age from nineteen to thirty nine participated in a four-stage study during which measurements of end tidal CO_2 (EtCO2 - by capnometer) and local brain oxygenation (by near-infrared spectroscopy ...

Effects of non-physiological blood pressure artefacts on measures of cerebral autoregulation [PDF]
arXiv, 2016 Cerebral autoregulation refers to regulation mechanisms that aim to maintain cerebral blood flow approximately constant. It is often assessed by autoregulation index (ARI), which uses arterial blood pressure and cerebral blood flow velocity time series to produce a ten-scale index of autoregulation performance (0 denoting the absence of and 9 the ...

Involvement of electrophysiological localization of the subthalamic nucleus in deep brain stimulation for Parkinson’s disease [PDF]
, 2008 We studied the involvement of the electrophysiological localization of the subthalamic nucleus (NST) using a multi-unit recording technique by means of semi-microelectrode in a set of thirty Parkinson’s patients who benefited from a bilateral stimulation
