Insights from cardiovascular magnetic resonance imaging supporting the selfish brain hypothesis of arterial hypertension
نویسندگان
چکیده
Background Brainstem hypoperfusion may evoke systemic hypertension as a mechanism to boost cerebral blood flow: the selfish brain hypothesis. This notion is supported by evidence of vertebral artery hypoplasia (VAH) in hypertensive rat models. We determined the prevalence of anatomical variations of posterior cerebral circulation which could predispose to brainstem hypoperfusion in a hypertensive human cohort.

Introduction: Despite growing interest in the use of magnetic resonance imaging (MRI) in the external radiotherapy design process (RT), Computer Tomography (CT) remains a gold standard and is regarded as a basic imaging modality in radiotherapy. MRI shows the high contrast in soft tissues without any radiation exposure to patients. As a result, MRI is used in functional tissue ...

In an attempt to assess objectively the integrity of the auditory pathways in 30 patients with definite multiple sclerosis (MS), an audiometric evaluation was performed and auditory brainstem responses (ABRs) were obtained. Stressing the auditory system by increasing the stimulation rate showed some enhancement in the identification of MS. 24 (RO%) patients had an abnormal ABR along with c...
متن کاملSegmentation of Magnetic Resonance Brain Imaging Based on Graph Theory
Introduction: Segmentation of brain images especially from magnetic resonance imaging (MRI) is an essential requirement in medical imaging since the tissues, edges, and boundaries between them are ambiguous and difficult to detect, due to the proximity of the brightness levels of the images. Material and Methods: In this paper, the graph-base...

BACKGROUND There are limited data on the prognostic value of cardiovascular magnetic resonance measurements in idiopathic pulmonary arterial hypertension, with no studies investigating the impact of correction of cardiovascular magnetic resonance indices for age and sex on prognostic value. METHODS AND RESULTS Consecutive patients with idiopathic pulmonary arterial hypertension underwent card...

Introduction: Nowadays, magnetic resonance imaging (MRI) in combination with computed-tomography (CT) is increasingly being used in radiation therapy planning. MR and CT images are applied to determine the target volume and calculate dose distribution, respectively. Since the use of these two imaging modalities causes registration uncertainty and increases department w...
