Comparison of apparent diffusion coefficients and distributed diffusion coefficients in high‐grade gliomas [PDF]

Journal of Magnetic Resonance Imaging, 2010
AbstractPurpose:To compare apparent diffusion coefficients (ADCs) with distributed diffusion coefficients (DDCs) in high‐grade gliomas.Materials and Methods:Twenty patients with high‐grade gliomas prospectively underwent diffusion‐weighted MRI. Traditional ADC maps were created using b‐values of 0 and 1000 s/mm2.

Pixel-based time–intensity curve analysis and apparent diffusion coefficient mapping of sinonasal organized hematomas [PDF]

, 2010
We present dynamic contrast-enhanced (DCE) and diffusion-weighted magnetic resonance imaging (MRI) features in three cases of sinonasal organized hematoma. The DCE MRI was evaluated by analyzing the time-intensity curve patterns on a pixel-by-pixel basis

The Apparent Diffusion Coefficient in Glial Tumors

OMICS Journal of Radiology, 2017
Background: Diffusion-Weighted Imaging (DWI) is one of the fast developing techniques in the field of MRI. This method uses the random diffusion motion of water molecule depending on physiological and anatomical characteristics of living organisms.

The trouble with apparent diffusion coefficient papers [PDF]

Journal of Medical Radiation Sciences, 2015
This issue of Journal of Medical Radiation Sciences includes a study (Rundle-Thiele et al.)1 that investigates the correlation between magnetic resonance imaging (MRI)-based estimates of water mobility in glioblastoma tumours and expression of the prognostically important gene promoter methylguanine methyltransferase (MGMT).
