Noise robust spatially regularized myelin water fraction mapping with the intrinsic B1-error correction based on the linearized version of the extended phase graph model

Abstract: The proposed method resulted in more accurate and noise robust myelin water fraction maps with improved depiction of subcortical WM structures.

“…[ 41 ] Although obtaining whole-brain MWF maps could be time-consuming and its accuracy can be subject to the image quality, a good relationship between derived MWF and histological results has been demonstrated in postmortem and animal studies. [ 42 ] Consequently, a combination of DKI and myelin water imaging may elucidate the underlying biomechanism of WM demyelination after CO intoxication.…”

“…Another penalty of losing image fidelity could result from the application of pre-processing median filter. Using a noise robust spatially regularized algorithm proposed by Kumar et al [ 42 ] could be a potential remedy. Finally, the spatial resolution in the present study is limited due to the relatively longer acquisition time of the DKI technique for humans, which may restrict further identification of subtle WM alterations after CO exposure.…”

“…The respective regression coefficient for the bivariate model, the related CI and p-value are shown below the respective plot region in light gray. reconstruction approach (Kumar et al, 2018) has been shown to result in improved noise robustness and better convergence compared to competing approaches (Prasloski et al, 2012a;Kumar et al, 2016). The resultant improved sensitivity has enabled us to detect age-related MWF changes more accurately.…”

“…The corresponding multi‐component analysis assumes smoothness in the normalT1,normalT2 parameter space and spatial smoothness to determine normalT1,normalT2 distributions for all voxels. This method can be seen as an extension on T2NNLS methods where spatial smoothness is applied and multiple relaxation parameters are simultaneously encoded. Six main peaks are detected in the reconstructed spectrum, which are interpreted as 6 different components.…”
