Figure 4From: Brain perfusion in fibromyalgia patients and its differences between responders and poor responders to gabapentinComparison of regional cerebral blood flow (rCBF) between the responder group and the poor responder group. Maximum intensity projections of Statistic Parametric Mapping 2 (SPM2) results from comparison of rCBF between the responder and poor responder groups are shown. (a, b) The poor responder group exhibited hyperperfusion in the right middle temporal gyrus, left middle frontal gyrus, left superior frontal gyrus, right postcentral gyrus, right precuneus, right cingulate, left middle occipital lobule, and left declive. Height threshold is less than 0.001, corrected for multiple comparison.Back to article page
