Is absolute quantification in proton magnetic resonance spectroscopy useful to differentiate amnesic mild cognitive impairment from Alzheimer 's disease and healthy aging?
Using a single-voxel (1)H-MRS at a short TE, we revealed that absolute quantification is useful to detect the characteristic patterns of metabolite concentrations in patients with aMCI as compared with AD patients and HCs.
Among patients who underwent redo-AF ablation, those with more PV reconnections showed better clinical outcomes than those with fewer PV reconnections. The mechanism of AF recurrence might be different in patients with lower numbers of PV reconnections during redo-procedures.
