Contrast enhancement by combining T1- and T2-weighted structural brain MR Images
2014
Magnetic Resonance in Medicine
Purpose-In order to more precisely differentiate cerebral structures in neuroimaging studies, a novel technique for enhancing the tissue contrast based on a combination of T1-weighetd (T1w) and T2-weighed (T2w) magnetic resonance imaging (MRI) images was developed. Methods-The combined image (CI) was calculated as CI = (T1w−sT2w)/(T1w+sT2w), where sT2w is the scaled T2-weighted image. The scaling factor was calculated to adjust the gray matter voxel intensities in the T2w image so that their
