juvenile fibroadenoma is an uncommon histologic variant of fibroadenoma that frequently shows a remarkable and rapid growth. the development of a carcinoma within a fibroadenoma, either in situ or invasive, is a rare condition. we encountered a 36-year-old woman with a palpable mass in the right breast. the radiologic findings were indicative of a fibroadenoma in the breast. sonographic guided ...

background diffusion-weighted imaging (dwi) is a form of magnetic resonance imaging (mri) based on measuring the random brownian motion of water molecules within the biological tissues and is particularly useful in tumor characterization. objectives the purpose of this study was to evaluate the diagnostic value of dw mri and the apparent diffusion coefficient (adc) for preoperative grading of a...

Neuroimaging Neuroimaging is divided into three types: diagnostic, functional, and morphometric or structural imaging. As the name implies, the first is used to rule out conditions such as a brain tumor (computer tomography and magnetic resonance imaging [MRI] scans), whereas functional imaging (e.g., positron emission tomography or functional MRI) is used to investigate how the brain works in ...

Introduction: Bacterial meningitis is an acute infectious inflammation of the protective membranes covering the brain. Its early diagnosis is vital because of its high morbidity and mortality. It is mostly diagnosed by a gold standard diagnostic tool i.e. Cerebrospinal Fluid (CSF) analysis. However, it is sometimes difficult and or impossible to do this procedure and an alternative diagnostic t...

With the rise of aging population, clinical concern and research attention has shifted towards neuroimaging of dementia. The advent of 3T, magnetic resonance imaging (MRI) has permitted the anatomical imaging of neurodegenerative disease, specifically dementia, with improved resolution. Furthermore, more powerful techniques such as diffusion tensor imaging, quantitative susceptibility mapping, ...

background hepatic fibrosis is a typical complication of chronic liver diseases resulting in cirrhosis that remains a major public health problem worldwide. liver biopsy is currently the gold standard for diagnosing and staging hepatic fibrosis. percutaneous liver biopsy; however, is an invasive procedure with risks of complications. therefore, there is need for alternative non-invasive techniq...

the incidence of multiple myeloma (mm) affecting the jaws is 30% and on rare occasions the oral involvement can be the first indication of the disease. authors report a case of mm in a 40-yearold woman who presented with a multilocular radiolucent lesion in the left mandible initially mistaken as an ameloblastoma. conventional radiographs revealed a multilocular lesion on the molar region. comp...

This review covers the current approach to neuroimaging in epilepsy. Some conceptual considerations for the interpretation of neuroimaging findings are also discussed. An algorithm for neuroimaging in the presurgical evaluation of epilepsy patients is presented, and recommendations are given for specific magnetic resonance imaging (MRI) protocols. The typical findings on MRI, including function...
