Dedicated To my loving wife for her utmost efforts to make impossible, possible To my kids and my parents Parts of the thesis have been published previously in: Alterations in auditory change detection associated with tinnitus residual inhibition induced by auditory electrical stimulation. Auditory middle latency responses differ in right-and left-handed subjects: An evaluation through topograp...
Background and Purpose: Cardiopulmonary resuscitation with external chest compression generates low perfusion pressures that may be inadequate for restoring cerebral metabolism and may worsen intracellular pH. We tested the hypothesis that cerebral reperfusion with a low perfusion pressure after arrest restores brain adenosine triphosphate (ATP) and pH to levels attained at the same perfusion p...
Perfusion imaging of brain tumors has been performed by using various tracer and nontracer modalities and can provide additional physiologic and hemodynamic information, which is not available with routine morphologic imaging. Tumor vascular perfusion parameters obtained by using CT or MR perfusion have been used for tumor grading, prognosis, and treatment response in addition to differentiatin...
BACKGROUND Recently, modifications of Aβ1-42 levels in CSF and plasma associated with improvement in memory and language functions have been observed in patients with mild-moderate Alzheimer's disease (AD) treated with plasma exchange (PE) with albumin replacement. OBJECTIVE To detect structural and functional brain changes in PE-treated AD patients as part of a Phase II clinical trial. MET...
Measurements of cerebral perfusion have become an important part of diagnostic imaging and therapy monitoring in a variety of brain diseases. Magnetic resonance perfusion imaging provides high-resolution images of various perfusion parameters in addition to the important morphological information acquired during the same imaging session. In conjunction with magnetic resonance imaging (MRI) diff...
