Alzheimer’s Disease (AD) is the most prevailing type of dementia. The prevalence AD estimated to be around 5% after 65 years old and staggering 30% for more than 85 in developed countries. destroys brain cells causing people lose their memory, mental functions ability continue daily activities. findings this study are likely aid specialists decision-making process by using patients’ Magnetic Re...

The purpose of this study was to determine if administration of gadopentetate dimeglumine aids in the MR detection of optic nerve lesions in patients with acute optic neuritis and to establish an efficient MR imaging protocol to effectively demonstrate such lesions. Patients with acutely decreased visual acuity were referred for MR imaging of the brain and orbits. Predominantly, T1-weighted ima...

Magnetic resonance (MR) imaging and computed tomography (CT) are useful for the evaluation of central nervous system (CNS) lupus. This report describes the use of cranial MR and CT in 21 patients with systemic lupus erythematosus (SLE) with acute neuropsychiatric symptoms manifested by headache, seizures, focal neurological deficits, psychosis, or organic brain syndrome. Computed tomography was...

PURPOSE To describe the MR characteristics of optic neuropathy caused by vasculitis. METHODS Nine cases of optic neuropathy with diagnosis of vasculitis (six with systemic lupus erythematosis and one each with rheumatoid arthritis, Sjögren disease, and radiation vasculitis) were reviewed retrospectively. Patients were 31 to 62 years old, and all but one were women. All patients had MR imaging...

Among the currently available brain tumor imaging, advanced MR imaging techniques, such as diffusion-weighted MR imaging and perfusion MR imaging, have been used for solving diagnostic challenges associated with conventional imaging and for monitoring the brain tumor treatment response. Further development of advanced MR imaging techniques and postprocessing methods may contribute to predicting...

PURPOSE To characterize the MR findings in children with spastic tetraplegia by gestational age at birth and perinatal history. METHODS Thirty-four children, 19 boys and 15 girls, with spastic tetraplegia whose brain damage occurred in the prenatal or perinatal period were included in the study. Eighteen were born at term or later and 16 were premature. Axial proton density- and T2-weighted i...

In the field of Automation, Fuzzy Control Fuzzy control has significant merits which are utilized in intelligent controllers, especially for vibration control systems. This paper is concerned with the application aspects of the developed MR damper for landing gear system, to attenuate the sustained vibrations during the landing phase. Also a comparative study is made on the responses obtained f...
