Physiological Mechanisms and Significance of Intracranial B Waves

Autor: David W. Newell, Maiken Nedergaard, Rune Aaslid

Publikováno v: Frontiers in Neurology, Vol 13 (2022)

ObjectiveRecently published studies have described slow spontaneous cerebral blood flow (CBF) and cerebrospinal fluid (CSF) oscillations measured by magnetic resonance imaging (MRI) as potential drivers of brain glymphatic flow, with a similar freque

Determination of Effective Orifice Area in Mitral Stenosis from Non-invasive Ultrasound Doppler Data and Mitral Flow Rate

Autor: Rune Aaslid, Knud Landmark, Jarle Holen, Svein Simonsen, Tønnes østrem

Publikováno v: Acta Medica Scandinavica. 201:83-88

Ten patients with mitral stenosis, but without mitral insufficiency, have been studied during cardiac catheterization. The mitral orifice blood velocities, the mitral pressure gradient, and the mitral flow rate were determined with ultrasound, manome

Ambulatory Transcranial Doppler Cerebral Embolic Signal Detection in Symptomatic and Asymptomatic Carotid Stenosis

Autor: Hugh S. Markus, Rune Aaslid, Andrew D. Mackinnon

Publikováno v: Stroke. 36:1726-1730

Background and Purpose— Transcranial Doppler (TCD) ultrasound can detect asymptomatic emboli in carotid stenosis. Current systems are nonportable and can only record for short durations. A novel ambulatory TCD system allows prolonged recording. We

Dynamic Pressure–Flow Velocity Relationships in the Human Cerebral Circulation

Autor: William H. Gild, Gust H. Bardy, David W. Newell, Stephanie R. Lash, Rune Aaslid

Publikováno v: Stroke. 34:1645-1649

Background and Purpose— The pressure–flow velocity relationship in the cerebral circulation is characterized by the critical closing pressure (CCP), which is the pressure at which flow ceases, and the linear slope of a plot between pressure and f
