Apparent diffusion coefficient mapping of the normal parotid gland and parotid involvement in patients with systemic connective tissue disorders.
PURPOSE We hypothesized that a difference in restricted diffusion would exist in patients with connective tissue disorders (CTD) as compared with those without CTD. Our purpose was to determine whether the apparent diffusion coefficient (ADC) measurement could be used to identify parotid abnormalities in patients with CTD. METHODS One neuroradiologist, who was unaware of patient histories, re...
متن کاملDiffusion-weighted imaging of the parotid gland: Influence of the choice of b-values on the apparent diffusion coefficient value.
PURPOSE To determine how the ADC value of parotid glands is influenced by the choice of b-values. MATERIALS AND METHODS In eight healthy volunteers, diffusion-weighted echo-planar imaging (DW-EPI) was performed on a 1.5 T system, with b-values (in seconds/mm2) of 0, 50, 100, 150, 200, 250, 300, 500, 750, and 1000. ADC values were calculated by two alternative methods (exponential vs. logarith...
متن کاملExploring the Possibility of Estimating Degree of Glioma Tumors by Measuring Apparent Diffusion Coefficient
Introduction: Most common glioma tumors are tumors of the central nervous system (CNS) which are the cause of about 40 to 50 percent of brain tumors. This type of cancer includes 2 to 3 percent of cancers in the world. Conventional MRI is powerless in the detection and differentiation of benign and malignant tumors. In this case, diffusion weighted imaging (DWI) can create cont...
متن کاملA Potential Risk of Overestimating Apparent Diffusion Coefficient in Parotid Glands
OBJECTIVES To investigate transient signal loss on diffusion weighted images (DWI) and overestimation of apparent diffusion coefficient (ADC) in parotid glands using single shot echoplanar DWI (EPDWI). MATERIALS AND METHODS This study enrolled 6 healthy subjects and 7 patients receiving radiotherapy. All participants received dynamic EPDWI with a total of 8 repetitions. Imaging quality of DWI...
متن کاملSclerosing Mucoepidermoid Carcinoma of the Parotid Gland
Introduction: Mucoepidermoid carcinoma represents one of the most common malignant salivary gland tumors.However, the sclerosing morphologic variant is extremely rare with only 23 reported cases in the English-language literature since it was discovered in 1987. Case Report: Herein, we describe another case that was diagnosed in a 25-year-old woman presenting with a posterior auricular mass, ...
