Estudio de correlación clínico-radiológica, sensibilidad y especificidad de ecotomografía transcraneana en enfermedad de Parkinson y otros trastornos del movimiento
(2011)
Background: The detection of hyperechogenicity of the substantia nigra using
trans cranial sonography can be predictive of the diagnosis of Parkinson Disease. Aim:
To report an experience with transcranial sonography for ...
No Relationship Between Patent Foramen Ovale and Migraine Frequency
(Blackwell Publishing Inc., 2016)
© 2016 American Headache SocietyBackground: Pathophysiology of migraine is not fully known. A link has been proposed between migraine and patent foramen ovale (PFO). However, there are conflicting data regarding the causal ...
Flat-head positioning increases cerebral blood flow in anterior circulation acute ischemic stroke. A cluster randomized phase IIb trial
(SAGE Publications Inc., 2018)
© 2017 World Stroke Organization. Background: Whether lying-flat improves blood flow in patients with acute ischemic stroke is unknown. Our aim was to investigate if lying-flat “changes” cerebral blood flow velocities ...
Flat-head positioning increases cerebral blood flow in anterior circulation acute ischemic stroke. A cluster randomized phase IIb trial
(Sage, 2018)
Background: Whether lying-flat improves blood flow in patients with acute ischemic stroke is unknown. Our aim was
to investigate if lying-flat ‘‘changes’’ cerebral blood flow velocities assessed by transcranial Doppler ...

Additional information given to a multimodal imaging stroke protocol by transcranial doppler ultrasound in the emergency room: A prospective observational study
(2010)
Background: Transcranial Doppler (TCD) ultrasound can
demonstrate dynamic information. We aimed to evaluate
whether TCD generates useful additional information in the
emergency room after a multimodal stroke imaging ...
Head position and cerebral blood flow velocity in acute ischemic stroke: A systematic review and meta-analysis
(S. Karger AG, 2014)
Background: Patients with acute ischemic stroke (AIS) have impaired vasomotor reactivity, especially in the affected cerebral hemisphere, such that they may depend directly on systemic blood pressure to maintain perfusion ...
