Single voxel MRS is prone to partial volume contamination.
Only in (near) transmurally infarcted segments was ATF significantly reduced, most likely due to wall thinning, as ATF is prone to partial volume effects.
These structures are mainly made of CSF, which may appear contrasted on T1 and T2-weighted MR acquisitions, but they also are prone to partial volume effects.
The ROI and VOI methods yield graphical outputs with good signal-to-noise ratio, but lack spatial resolution and are prone to partial volume averaging errors.
This removes the white matter at the junctions with cerebrospinal fluid and grey matter that is prone to partial volume effects.
Whole tumour ROIs yield outputs with good signal-to-noise ratio, but lack spatial resolution and are prone to partial volume averaging errors and thus are unable to evaluate tumour heterogeneity.
ROI methods yield enhancement curves with good signal-to-noise ratio, but lack spatial resolution, are prone to partial volume averaging errors and ignore the heterogeneity of tumour enhancement.
All control channels are modeled to be prone to errors, leading to losing partial CSI of the system at the CU and/or losing precoded user data at the cooperating TNs.
may be prone to low blood sugar.
