Multiplanar computed tomography reconstruction to aid in recognition of the middle cerebral artery “Dot” sign: The sagittal string sign

SAGE Open Medical Case Reports, 2017
While non-contrast head computed tomography is effective in detecting blood, it is not sensitive in diagnosing hyperacute ischemic stroke. One neuroradiologic marker for early thromboembolic occlusion of the distal middle cerebral artery is the middle ...

Animal models of ischaemic stroke and characterisation of the ischaemic penumbra [PDF]

, 2018
Over the past forty years, animal models of focal cerebral ischaemia have allowed us to identify the critical cerebral blood flow thresholds responsible for irreversible cell death, electrical failure, inhibition of protein synthesis, energy depletion ...

Magnetic resonance investigation into the mechanisms involved in the development of high-altitude cerebral edema [PDF]

, 2017
Rapid ascent to high altitude commonly results in acute mountain sickness, and on occasion potentially fatal high-altitude cerebral edema. The exact pathophysiological mechanisms behind these syndromes remain to be determined.

Triptans and CGRP blockade - impact on the cranial vasculature [PDF]

, 2017
The trigeminovascular system plays a key role in the pathophysiology of migraine. The activation of the trigeminovascular system causes release of various neurotransmitters and neuropeptides, including serotonin and calcitonin gene-related peptide ...

Bilateral middle cerebral artery occlusions: Case report detailing successful treatment with timely mechanical thrombectomy

Radiology Case Reports, 2020
Bilateral middle cerebral artery occlusion is a very rare and dangerous pathology, accounting for less than 1% of stroke presentations. Unless treated, the natural course of the disease leads to coma or death and thus is extremely important to be ...

Doppler colour flow imaging of fetal intracerebral arteries relative to fetal behavioural states in normal pregnancy [PDF]

, 1994
In 14 normally developing term fetuses, the relationship between the blood flow velocity waveforms at cerebral arterial level (internal carotid artery, anterior, middle and posterior cerebral artery) and fetal behavioural states was studied using Doppler
