Aim: We aimed to determine the relationship between apparent diffusion coefficient (ADC) values obtained from diffusion-weighted images, histopathological fibrosis, and activity stages in patients with chronic hepatitis B infection. 
 Material Method: A total of 30 admitted our hospital September 2012 June 2014 were included study. All underwent biopsy abdomen MRI examination before treatm...

UNLABELLED WHAT IS KNOWN ABOUT THIS SUBJECT?: Diffusion-weighted MRI has demonstrated changes in the corpus callosum of term neonates with perinatal asphyxia. The severity of cerebral changes demonstrated using diffusion-weighted MRI is difficult to assess without measuring values of the Apparent Diffusion Coefficient (ADC). WHAT IS NEW?: ADC values of the anterior part of the corpus callosum a...

The aim was to determine the utility of diffusion-weighted magnetic resonance imaging (DW MRI) and apparent diffusion coefficient (ADC) measurements in differentiation of endometrioma and hemorrhagic ovarian cyst. A total of 24 female patients who underwent pelvic MRI with an initial diagnosis of ovarian cyst were included in the study. The final diagnosis was endometrioma in 12 patients and he...

The characteristics of multiple sclerosis (MS) lesions on diffusion-weighted sequences and apparent diffusion coefficient (ADC) mapping at the very early phase of symptoms have not been clearly described. We report the case of a young woman who presented with a sudden pseudostroke form of MS resulting in hemiplegia and sudden aphasia. MR imaging showed a lesion of the left internal capsule with...

Introduction: Diffusion weighted imaging and in particular the apparent diffusion coefficient (ADC) are among the main lung gas MRI applications. Since ADC values are related to molecular mobility, they are expected to reflex changes in lung microstructure, and hence be used as a detector for early stage lung diseases. Long-range diffusion can instead provide information about the microstructur...

BACKGROUND AND PURPOSE The pathogenesis of cerebral venous infarction (CVI) remains controversial, with uncertainty over whether cytotoxic edema plays a role. Recent animal studies have shown that cytotoxic edema reliably occurs in acute CVI and precedes the onset of vasogenic edema. Our hypothesis was that cytotoxic edema would also occur in acute human CVI and would be detectable as an area o...

BACKGROUND We tested the feasibility of a simple method for assessment of prostate cancer (PCa) aggressiveness using diffusion-weighted magnetic resonance imaging (MRI) to calculate apparent diffusion coefficient (ADC) ratios between prostate cancer and healthy prostatic tissue. METHODS The requirement for institutional review board approval was waived. A set of 20 standardized core transperi...

BACKGROUND Diffusion-weighted imaging (DWI) is an MRI modality using strong bipolar gradients to create a sensitivity of the signal to the thermally-induced Brownian motions of water molecules and in vivo measurement of molecular diffusion. The apparent diffusion coefficient (ADC) is a quantitative parameter calculated from DWI images which is used as a measure of diffusion. DWI allows to obtai...

PURPOSE The aim of this study was to explore the diagnostic effectiveness of magnetic resonance (MR) spectroscopy with diffusion-weighted imaging on the evaluation of the recurrent contrast-enhancing areas at the site of treated gliomas. METHODS AND MATERIALS In 55 patients who had new contrast-enhancing lesions in the vicinity of the previously resected and irradiated high-grade gliomas, two...

INTRODUCTION The mismatch between the perfusion and diffusion abnormality – widely considered to approximate the ischemic penumbra – indicates tissue at risk for infarction but potentially salvageable [1]. The perfusion-diffusion mismatch has been utilized to guide thrombolytic therapy and offers predictive value of ischemic tissue fate. Predictive models have employed multiple acute MRI parame...
