PMs have an altered signal on cine MRI. In particular, we sought to demonstrate that in MVP the signal intensity (SI) of the PMs is typically lower compared to that of LV parietal myocardium as measured on cine images. Furthermore, we looked into a possible association of ...
Abnormal T2 -weighted MRI signal surrounding leads in a subset of deep brain stimulation patients [J]. Stereotactic & Functional Neurosurgery,2011,89(5) :311-317.DJ Englot; CM Glastonbury; PS Larson.Abnormal T2 -weighted MRI signal surrounding leads in a subset of deep brain stimulation ...
A predicted group by drug interaction was noted in the dorsal medial prefrontal cortex (dmPFC) as well as right superior frontal gyrus and left and right occipital regions, such that psychosis patients showed an increased BOLD signal to LRZ challenge, rather than the decreased signal exhibited by...
A heart rate may signal an underlying health concern when the resting heart rate is above 100 bpm or under 60 bpm. A heart rate that is above 100 bpm and too fast is calledtachycardia. A heart rate that is too slow and below 60 bpm is calledbradycardia. When you’re active during the...

First, it is likely that individuals with an autism spectrum disorder process faces in a different manner than normal subjects, relying more on feature-based than configural analyses.10,11 The reduced FG and increased ITG activation may relate to such a difference, since the FG seems specialized...
However, few reports have corroborated that intracranial epidermoid cysts exhibit unusual appearance on CT and MRI scans owing to the presence of calcification, albumin, iron, copper and increased level of protein [[1], [2], [3],5]. In the present study, we report an atypical extracranial ...
Based on this prevailing model and previous findings from studies of OCD, it is hypothesized that, compared with healthy controls, the corticostriatal-limbic regions of OCD patients would show increased FC during resting-state and reduced FC during incentive processing. Specifically, this altered ...
On the contrary, summarizing 50 whole-brain-based fMRI studies Chen et al (2011) found abnormally increased activation in BD patients relative to HC in the parahippocampus, hippocampus, and the amygdala. Overall, most fMRI studies comparing BD patients with HC were conducted in manic or remit...
Thus, the above-mentioned MEG study19 further reported decreased alpha synchro- nization in the right PCC associated with increased levels of CSF phosphorylated tau. Finally, anomalies in memory-related EEG oscillations could also be partially due to disruption of fast synap- tic inhibition mediated...
