چکیده انگلیسی
Proton-electron double-resonance imaging (PEDRI) was recently employed to monitor the process of formation of a calcium alginate hydrogel at a field of 16Â mT. Here, under the same experimental conditions, images obtained through this technique are compared to images obtained by conventional T2-weighted method. The results confirm that the image contrast obtained using PEDRI, thanks to the Overhauser effect, exhibits an improved sensitivity with respect to changes in water mobility as previously suggested in the literature. Furthermore, by increasing the echo time interval for the T2-weighted images, important features of the gelling dynamics obtained via PEDRI could not be reproduced.
