Apparent diffusion coefficients in oligodendroglial tumors characterized by genotype [PDF]

Journal of Magnetic Resonance Imaging, 2007
AbstractPurposeTo investigate whether oligodendroglial tumors with or without 1p/19q loss differ in their diffusion‐weighted imaging characteristics. Oligodendroglial tumors with or without 1p/19q loss differ in their therapeutic responsiveness and prognosis, and recent reports also suggest that these tumors may differ in their magnetic resonance ...

Application of Diffusion-Weighted Imaging in the Detection of Active Sacroiliitis and the Comparison of Apparent Diffusion Coefficient and Relative Apparent Diffusion Coefficient Values

Archives of Rheumatology, 2016
Objectives: This study aims to evaluate the role of diffusion-weighted imaging in detection of active sacroiliitis and compare the apparent diffusion coefficient (ADC) and normalized relative ADC (r-ADC) values by using vertebra and iliac wings as reference organs. Patients and methods: The study included 56 patients (26 males, 30 females; mean age 37.

Apparent diffusion coefficient as a prognostic factor in clival chordoma

Scientific Reports, 2021
Clival chordoma is a rare disease with high recurrence rates even after a combination of surgical resection and radiotherapy. Apparent diffusion coefficient (ADC) has been used to evaluate aggressive features of chordoma, but its utility for clival ...

Hyperglycaemia does not increase perfusion deficits after focal cerebral ischaemia in male Wistar rats [PDF]

, 2018
Background: Hyperglycaemia is associated with a worse outcome in acute ischaemic stroke patients; yet the pathophysiological mechanisms of hyperglycaemia-induced damage are poorly understood.

The Effect of the Surroundings to the Apparent Diffusion Coefficient on Diffusion Weighted Imaging

Japanese Journal of Radiological Technology, 2010
Diffusion weighted imaging (DWI) is now widely used in magnetic resonance (MR) imaging of the head and body. Moreover, the Apparent diffusion coefficient (ADC) value is often used for the differential diagnosis of the tumor. However, the effect of the surroundings on the ADC value has not been reported.
