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.

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
