Dynamic Contrast Magnetic Resonance Imaging (DCE-MRI) and Diffusion Weighted MR Imaging (DWI) for Differentiation between Benign and Malignant Salivary Gland Tumors
Background: Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. Objective: The majority of these tumors are benign; however, sometimes they tend to transform into a malignant form. Functional M...
متن کاملCT and MRI of an unusual intranasal mass: pleomorphic adenoma.
A rare case of pleomorphic adenoma arising from the nasal septum is presented. Computed tomography (CT) and magnetic resonance imaging (MRI) of a 65- year-old woman who presented with right sided nasal obstruction, nasal discharge and epistaxis revealed a well-defined lobular mass occupying the right nasal cavity. Histopathologic examination revealed a pleomorphic adenoma. CT and MRI findings o...
متن کاملdiffusion weighted mri for hepatic fibrosis: impact of b-value
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...
متن کاملDifferentiation between benign and malignant breast lesions using quantitative diffusion-weighted sequence on 3 T MRI.
AIM To investigate the capability and diagnostic accuracy of diffusion-weighted imaging (DWI) in differentiating benign from malignant breast lesions using 3 T magnetic resonance imaging (MRI). MATERIALS AND METHODS Women with suspicious or indeterminate breast lesions detected at MRI, mammogram and/or ultrasound were recruited for dynamic contrast-enhanced (DCE)-MRI and DWI prior to their bi...
متن کاملMetastasizing pleomorphic salivary adenoma.
OBJECTIVE To address questions about the etiology, behavior, optimal treatment, and prognosis of metastasizing pleomorphic adenoma (MPA), we undertook a review of the literature (1953-2005) and constructed a virtual series of all identified cases of MPA, metastatic lesions that are very occasionally identified in patients with a history of pleomorphic salivary adenoma and, on detailed pathologi...
