T2 signal abnormality was seen more commonly in scans obtained 3 or more days after surgery than in those collected immediately postoperatively. No differences in age, anatomical target, diagnosis, or number of microelectrode passes were noted between patients with or without T2 signal. Further ...

Children who are born preterm without subse- quent major neurodisability may, in addition to visible lesions on MRI scans, have a diffuse abnormality of CWM, manifest as an increase in T2 relaxation time. This abnormality shows a close correlation with minor motor impairment but not with full-...

In 20 of these, the areas of increased T2 signal concurred with epileptiform EEG abnormality and clinical seizure semiology. Group analysis of MRI- negative patients with electroclinical seizure onset localizing to the left and right temporal and left and right frontal regions revealed increased T2 ...

(but P > 0.05).There was inverse correlation between some hippocampal subfields T2 signal intensity and the scores of MMSE.Conclusion There is abnormality of some hippocampal subfields T2 signal intensity,and the quantitative measurement early of the left hippocampal head is useful in m...
T2-weighted MRI showed no significant abnormality in signal intensity from the occluded hemisphere within several hours post-occlusion. Using a paramagnetic MR contrast agent, dysprosium-DTPA-BMA together with heavily T2-weighted spin-echo or with T2*-weighted echo-planar (EPI) MR imaging, perfusion...
