the application of magnetic resonance to diagnostic medical imaging stands as one of the great scientific achievements in the past 50 years. magnetic resonance techniques are easily applied to organs which remain stationary during the imaging procedure, such as the brain and musculoskeletal system. imaging of moving heart structures and circulating blood is considerably more difficult. clinic...
case presentation we report a 5-year-old boy, who was presented with sudden right hand monoparesis and dysarthria. conclusions the patient was investigated with magnetic resonance angiography and diagnosed as md. introduction moyamoya disease (md) is a disorder caused by blocked arteries at the base of the brain. as the normal blood vessels narrow and become blocked, a person may suffer a strok...
o bjectives: to determine the diagnostic accuracy of magnetic resonance angiography (mra) compared to intra-arterial digital subtraction angiography (dsa) in detection of intracranial aneurysms in those suffering from acute subarachnoid hemorrhage (sah). m e thods: this observational diagnostic study was performed at a tertiary teaching hospital and reference center in shiraz, iran. we included...
a retroesophageal right subclavian artery as the last branch of the aortic arch- in vivo case report
three major arteries normally originate from the aortic arch. variations of the aortic arch branches are observed in some cases. rare variation of the aortic arch branches is originated from the retroesophageal right subclavian (rrs) artery as the last branch of the aortic arch. variation of artery is possibly associated with the variation of the recurrent laryngeal nerve. this research provide...
dissection of the internal carotid artery (ica) is a rare condition that accounts for a significant proportion of ischemic strokes in young adults. iatrogenic dissection as a complication of neurointerventional procedures is a traumatic dissection which has been reported relatively rare in the literature. in this report, a case of dissection of the ica is reported that was caused by repetitive ...

Background: A retrospective study of five patients with the clinical or magnetic resonance-based diagnosis of carotid dissection was done. Clinical data, imaging studies, treatment, and outcome were reviewed. The potential applicability of three-dimensional time-of-flight magnetic resonance angiography in these settings was evaluated. Summary of Report: This modality reliably showed vascular ab...
background: there are conficting reports regarding the association between coronary artery disease (cad) and mild cognitive impairment (mci). volumetric magnetic resonance imaging (mri) investigations have been considered as an objective biomarker for mci. in this study, we determined the relationship between the regional brain volumes and the extent of cad in mci patients and cognitively no...
