STUDY OBJECTIVES The authors reviewed neuroimaging studies of obstructive sleep apnea (OSA) to summarize findings, evaluate their contribution to a current understanding of the neurophysiology of the disorder, and propose directions for future research. METHOD Manuscripts were identified using the National Institutes of Health PubMed literature search system. Search terms included obstructive...

symptomatic laryngeal chondrometaplasia is rare. to the best of our knowledge, there are only few case reports on laryngeal chondrometaplasia. the imaging appearance of this uncommon disease is even more rarely described. there are only two case reports describing its appearances in computed tomography (ct) and magnetic resonance imaging (mri). ultrasound (us) features have not been reported so...

BACKGROUND Tissue-based research has recently led to a new patho-mechanistic model of essential tremor (ET)-the cerebellar degenerative model. We are not aware of a study that has reviewed the current neuroimaging evidence, focusing on whether the studies support or refute the neurodegenerative hypothesis of ET. This was our aim. METHODS References for this review were identified by searches ...

Background: Glucose transporter (Glut), a cellular transmembrane receptor, has a key role in the metabolism of cell glucose and is also associated with various human carcinomas.Objective: In this study, we evaluated a magnetic resonance (MR) imaging contrast agent for tumor detection based on paramagnetic gadolinium oxide (Gd2O3) coated polycyclodextrin (PCD) and mod...

background: arachnoid cysts are cerebrospinal fluid (csf) fluid-filled sacs that are located between the brain and spinal cord. spinal column arachnoid cysts are rare and mostly asymptomatic, being mostly located in intradural regions. we reported a patient who presented with neurological deficits and mid-thoracic extradural arachnoid cyst treated with en-bloc resection. case presentation: pati...

Recognition of childhood stroke is difficult. Newer diagnostic modalities like magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) have made this task much easier. Head trauma usually causes hemorrhage. We are presenting seven cases of mild head injury presenting as ischamic stroke. Neuroimaging suggested infarct involving left basal ganglia and internal capsule in five an...

conclusion both techniques provided quantitatively consistent results of in vivo velocity vector fields in right internal carotid artery (rca). pc mri represented a good estimation of main flow patterns inside the vasculature, which seems to be acceptable for clinical use. however, limitations of each technique should be considered while interpreting results. subjects and methods mr imaging was...

the purpose of this study was to investigate magnetic resonance imaging (mri) of the normal feline eyeand optic nerves using t1-weighted and t2-weighted images. a total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. magnetic resonance imaging data werecollected using gemsow (philips) at a magnetic field strength of 1.5 t. dorsal, sagittal, a...
