Intrinsic Brain Abnormalities in Patients with Hepatitis C Virus Infection with Cognitive Impairment: A Preliminary Resting-State fMRI Study

Figure 2

Brain regions showing decreased ALFF in patients with HCV infection. The patients showed lower ALFF values in two prefrontal regions, including ROI-1 (left medial frontal gyrus and bilateral anterior cingulate gyrus) and ROI-2 (right middle and superior frontal gyrus). The letters “L” and “R” represent the left and right sides, respectively.
