Background: Alzheimer's disease (AD) is the most common disorder of dementia, which has not been cured after its occurrence. AD progresses indiscernible, first destroy the structure of the brain and subsequently becomes clinically evident. Therefore, the timely and correct diagnosis of these structural changes in the brain is very important and it can prevent the disease or stop its progress. N...

introduction quantitative susceptibility mapping (qsm) is a new contrast mechanism in magnetic resonance imaging (mri). the images produced by the qsm enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. these nuclei are targets in many clinical applications and therefore their easy localization is a must. in this study, we aimed to i...

Objective(s): Systemic lupus erythematosus (SLE) is an autoimmune disease with a wide range of clinical manifestations. Cognitive dysfunction is one of the manifestations that could present prior to the emergence of any other neuropsychiatric involvements in SLE. Cognitive dysfunction is a subtle condition occurring with ahigh frequency. However, there is no data on the correlation of cognitive...

intraventricular tuberculoma (ivt) is extremely rare, ct and mri patterns have been only sparsely described.  herein, a case of intraventricular tuberculoma in a 40 year-old woman is reported.  at admission, the patient displayed malaise and was confused and deteriorated suddenly.  brain ct and mri findings were very similar to intraventricular meningioma.  the patient underwent surgery and tub...

Background: Neonatal seizures can have many causes. Determining the underlying cause of neonatal seizures is very important in determining the prognosis, outcome, and treatment strategies. In this study, we have evaluated the frequency of Magnetic resonance imaging (MRI) findings in neonates younger than 6 months who had been referred to Shiraz Namazi hospital with seizures to determine the pre...

a young patient who presented with headache followed by positive and negative symptoms of psychosis and mutism was sent for the mri of brain. mri revealed a lipoma in the quardrigeminal area. we hypothesized that the neuro-vascular encasement of structures located at the upper dorsal midbrain by the lipoma caused the symptoms. a review of the current literature of quadrigeminal lipoma cases wit...

Intracranial tumors are a type of cancer that grows spontaneously inside the skull. Brain tumor is cause for one in four deaths. Hence early detection important. For this aim, variety segmentation techniques available. The fundamental disadvantage present approaches their low accuracy. With help magnetic resonance imaging (MRI), preventive medical step and evaluation brain done. Magnetic (MRI) ...
