In cerebrovascular disorder diagnosis computer-aided diagnosis of intracranial aneurysms, segmenting of high-intensity major vessels along with the low-contrast aneurysms is essential to the recognition of lethal vascular disease. This paper proposes a novel intensity-based algorithm to segment intracranial vessels and the attached aneurysms. The proposed method can handle intensity varying vas...

We report a case of progeria and the utility of visualizing the cerebrovascular anatomy by using MR angiography. A 4-year-old child with Hutchinson-Guilford syndrome developed symptoms of ischemia and MR angiography showed bilateral occlusion of internal carotid and vertebral artery origins; the anterior spinal artery was prominent.

Cerebrovascular diseases are one of the serious causes for increase in mortality rate world which affect blood vessels and supply to brain. In order, diagnose study abnormalities cerebrovascular system, accurate segmentation methods can be used. The shape, direction distribution studied using automatic segmentation. This will help doctors envisage system. Due complex shape topology, is still a ...

ZusammenfassungComputed tomography angiography (CTA) is one of the most commonly used modalities in diagnosis cerebrovascular diseases like ischemic strokes. Usually, anatomy interest stroke cases Circle Willis and its peripherals, cerebral arteries, as these vessels are prominent candidates for occlusions. The occlusions remains challenging, not only because large amount surrounding but also d...

BACKGROUND AND PURPOSE Atherosclerotic calcifications are present not only in the extracranial carotid bifurcation but also in the intracranial part of the internal carotid artery. We assessed the association between intracranial internal carotid artery calcifications and cardiovascular risk factors in patients with ischemic cerebrovascular disease and the association between calcifications and...

Introduction: Surgery for cerebellar hemangioblastoma can be challenging because of the tumor's location in posterior fossa and its inherent nature hypervascularity. Solid HGB show characteristics arteriovenous malformation, internal decompression, or piecemeal resection, harbor risk potentially devastating intraoperative bleeding swelling. Indocyanine green (ICG) is widely used visualizing flo...

this report presents a case of vertebral artery dissection (vad), which was misdiagnosed as cerebrovascular accident (cva) in initial examinations.in this case, a 33-year old woman, who was involved in a car accident, was referred to khoy legal medicine centre by traffic court two months after the accident.the patient was examined by the author, who was on an assignment at the centre.at this ti...

Hypoglycemic hemiplegia mimics cerebrovascular disease. Two patients are reported who experienced multiple attacks of transient hemiplegia associated with hypoglycemia and who were initially diagnosed as having transient ischemic attacks. In both, angiography was normal and the attacks resolved with reduction of insulin dose. Recognition of hypoglycemia as the cause of transient hemiplegia is i...

Methods Children presenting to our neurovascular service and who had had cerebral and renal angiography, other than those with a final diagnosis of vasculitis, were eligible for inclusion. Cerebrovascular disease was categorized MM or other occlusive cerebrovascular disease (OCVD) using standard definitions. Case notes, imaging reports and renal angiograms were retrospectively reviewed. Hyperte...
