Spontaneous pain and brain activity in neuropathic pain: functional MRI and pharmacologic functional MRI studies.
Functional brain imaging studies in chronic neuropathic pain patients have lagged far behind equivalent studies in acute pain. In the past few years, this trend has begun to shift. This article discusses the novel approach of studying brain activity for spontaneous pain and its modulation by pharmacologic manipulation. We argue that the approach provides a solid methodology for studying clinica...
متن کاملPhysiological noise reduction for arterial spin labeling functional MRI.
Three methods for the reduction of physiological noise in arterial spin labeling (ASL) functional magnetic resonance imaging (fMRI) are presented and compared. The methods are based upon a general linear model of the ASL measurement process and on a previously described retrospective image-based method (RETROICOR) for physiological noise reduction in blood oxygenation level dependent fMRI. In t...
متن کاملAbnormal Spontaneous Brain Activity in Acute Low-Back Pain Revealed by Resting-State Functional MRI.
OBJECTIVE Neuroimaging studies have revealed that low-back pain (LBP) alters spatiotemporal dynamics of the blood oxygen level-dependent signal in response to persistent noxious stimulus. This study aimed to investigate changes in spontaneous neural activity of various brain regions in acute LBP using resting-state functional magnetic resonance imaging and amplitude of low-frequency fluctuation...
متن کاملAberrant spontaneous brain activity in chronic tinnitus patients revealed by resting-state functional MRI
OBJECTIVE The neural mechanisms that give rise to the phantom sound of tinnitus are poorly understood. This study aims to investigate whether aberrant spontaneous brain activity exists in chronic tinnitus patients using resting-state functional magnetic resonance imaging (fMRI) technique. MATERIALS AND METHODS A total of 31 patients with chronic tinnitus patients and 32 healthy age-, sex-, an...
متن کاملAltered Spontaneous Brain Activity in Patients with Hemifacial Spasm: A Resting-State Functional MRI Study
Resting-state functional magnetic resonance imaging (fMRI) has been used to detect the alterations of spontaneous neuronal activity in various neurological and neuropsychiatric diseases, but rarely in hemifacial spasm (HFS), a nervous system disorder. We used resting-state fMRI with regional homogeneity (ReHo) analysis to investigate changes in spontaneous brain activity of patients with HFS an...
