Diffusion weighted imaging, apparent diffusion coefficient maps and stroke etiology [PDF]

Journal of Neurology, 2018
Objective : In acute ischemic stroke, the number and distribution of lesions on diffusion weighted imaging (DWI) have been shown to give clues to the underlying pathogenetic mechanisms. The objective of this study was to determine whether lesion features

Isotropic apparent diffusion coefficient mapping of postnatal cerebral development [PDF]

Neuroradiology, 2018
Diffusion-weighted imaging (DWI) allows us to image the motion of tissue water. This has been used to demonstrate acute ischaemia. Diffusion imaging is also sensitive to water movement along neuronal tracts.

Heterogeneity of Apparent Diffusion Coefficients Within Infarcts [PDF]

Stroke, 2001
To the Editor: Back et al1 recently reported apparent diffusion coefficient (ADC) measurements in acute stroke, finding no ADC fluctuations in peri-infarct regions over a 15-minute period. The reported data are convincing with regard to the temporal stability of infarct area within the 15-minute time window studied.

Apparent diffusion coefficient of normal adrenal glands [PDF]

Radiologia Brasileira, 2016
Abstract Objective: To assess the feasibility and reliability of apparent diffusion coefficient (ADC) measurements of normal adrenal glands. Materials and methods: This was a retrospective study involving 32 healthy subjects, divided into two groups: prepubertal (PreP, n = 12), aged from 2 months to 12.5 years (4 males; 8 females); and postpubertal ...

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.

Apparent Diffusion Coefficient Values for Neuroendocrine Liver Metastases

Academic Radiology, 2021
We aimed to investigate whether there are any differences in apparent diffusion coefficient (ADC) values obtained from liver metastases due to gastroenteropancreatic neuroendocrine tumors (GEP-NET) and adenocarcinomas.We included 54 patients with 167 liver metastases due to gastroenteropancreatic tumors. We divided the patients into two groups as liver
