Differential MRI diagnosis between brain abscesses and necrotic or cystic brain tumors using the Apparent Diffusion Coefficient and Normalized Diffusion-Weighted

Magnetic Resonance Imaging 21 (6) 645-650

par Administrateur - publié le

Abstract :

Magnetic Resonance Diffusion-Weighted Imaging (DWI) has been reported to be helpful for the differential diagnosis between abscesses and cystic/necrotic brain tumors. However the number of patients is still limited, and the sensitivity and specificity of the method remain to be confirmed. The primary purpose of this study was to investigate a larger sample of patients, all investigated under the same experimental conditions, in order to obtain statistically significant data. Moreover, there is no consensus about the appropriate values of b required to use to make an accurate diagnosis from DWI.
