objective cerebral palsy (cp), a common static motor neurological disorder of childhood with wide spectrum of underlying etiologies, can be demonstrated with different neuro imaging techniques. we undertook this study to investigate the diagnosis of intracranial lesions in children with cp and its correlation between clinical deficits and neuroradiological findings. materials and methods in thi...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
In recent years, the development of neuroimaging techniques such as high-resolution magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), positron emission tomography (PET), or single photon emission tomography (SPECT) has promoted the identification of structural and functional characteristics underlying mental disorders to a great extent. In anxiety disorders, recent...

ABSTRACTNeuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. It is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. Neuroimaging modalities include X-ray computed tomography (CT), magnetic resonance imaging (MRI), single photon emis...
زمینه و هدف: سرطان پروستات سومین علت مرگ و شایع ترین علت سرطان در مردان مسن است. با توجه به توانایی تشخیصی پایین روش های غربالگری در تشخیص و لوکالیزه کردن تومور، روش های تصویربرداری از جمله magnetic resonance imaging (mri) و diffusion weighted imaging (dwi) در سال های اخیر مورد توجه و استقبال قرار گرفته است. در این تحقیق، ارزش استفاده از dwi برای تشخیص سرطان های پروستات بررسی گردید.روش بررسی: ا...
intracranial gliosis has no typical clinical signals or imaging characteristics. therefore, it can be easily misdiagnosed as neoplasm. hereby, we report a unique case of gliosis that grew outward from the surface of the brain. mri depicted its signal and enhancement pattern similar to the cerebral gray matter. the diagnosis was confirmed by pathology and immunohistochemistry. although it was di...

basic physical principles of nuclear magnetic resonance imaging (n.m.r.i), a nonionizing medical imaging technique, are described. principles of nmri with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. t1 and t2 and spin density (s.d.) factors and different image construction techniques based on their different combinations is discu...
