Pachygyria or incomplete lissencephaly is a developmental condition due to abnormal migration of neurons. The association of seizures in this condition warrants investigation like electroencephalogram (EEG) and magnetic resonance imaging (MRI). 18F-flurodeoxyglucose positron emission topography computed topography (18F-FDG PET/CT) has a potential role in commenting of wide...

As fluorine-18-fluorodesoxyglucose positron emission tomography/computed tomography ( (18)F-FDG PET/CT) is gaining wider availability, more and more patients with malignancies undergo whole body PET/CT, mostly to assess tumor spread in the rest of the body, but not in the brain. Brain is a common site of metastatic spread in patients with solid extracranial tumors. Gold standard in the diagnosi...

OBJECTIVE The advent of computed tomography (CT) scan revolutionized the diagnostic evaluation of neurologic patients. The aim of this study was to evaluate brain CT results of epileptic children. MATERIALS & METHODS In a descriptive cross-sectional study, noncontrast brain CT scan of 150 consecutive 1-18 year old epileptic children whom were referred to pediatric neurology clinic of Shahid S...

objective(s): in clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (dtc) patients with high serum thyroglobulin (tg) and negative 131i whole-body scan (wbs) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. the purpose of this study was to evaluate the value of 18f-fdg pet/ct scan in dtc patients with high seru...

background outcome determination of head trauma is important for medical decision-making. to determine the consequences by using ct findings, the marshall and rotterdam criteria were introduced. few studies have been conducted to determine the diagnostic value of the rotterdam criteria. objective this study assesses the diagnostic value of the rotterdam criteria score with early outcome for tra...

background : glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. this study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation. methods : the study was a cross-sectional study evaluating patients with unstable shoulder...

magnetic resonance imaging (mri) uses a constant magnetic field and radio waves, a non-invasive method for examining tissues, organs and the skeletal system. the advantages and disadvantages of mri is not fully understood. in the computerized tumor (ct) scan, as an invasive method, the x-rays of the body is used for tomography; which different x-ray attenuation coefficient in tissues as well as...

BACKGROUND In emergency medicine for determining the intracranial injury (ICI) in children with head trauma, usually brain CT scan is performed. Since brain CT scan, especially in children, has some disadvantages, it is better to find a procedure which could help to choose only the children with real head trauma injury for brain CT scan. AIMS The aim of this study is to find such procedure. T...

brain tumors are considered in regarded to their size, position and aggressive manner. brain tumors cause several neurologic symptoms. for instance, they increase intracranial pressure due to local damage and displacement of surrounding tissues. in this paper, two glioblastoma multiform cases with more than 15 year- survival have been reported. the first patient was a 52 year- old woman who suf...
