چکیده
images obtained from (b) hypercapnia and (c) ischemia study, respectively, during Stages 2 to 3. The time indicated below is the image sampling time after the termination of Stage 2 (S2). The arrows point to the sinus vessel. The total image averaging times for Stages 2 to 3 (i.e., S2, S3) were: 2.5, 6.5 minutes for the hypercapnia study; and 1.0, 1.8 minutes for the ischemia study. Stage 2 Stage 3 10% -30% BOLD (Ischemia) 0 -2% 5% BOLD (Hypercapnia) 0 1.35 -1.35 (ml/g/min) ΔCBF 0

Simultaneous Imaging of CBF Change and BOLD with Saturation-Recovery-T1 Method
A neuroimaging technique based on the saturation-recovery (SR)-T1 MRI method was applied for simultaneously imaging blood oxygenation level dependence (BOLD) contrast and cerebral blood flow change (ΔCBF), which is determined by CBF-sensitive T1 relaxation rate change (ΔR1CBF). This technique was validated by quantitatively examining the relationships among ΔR1CBF, ΔCBF, BOLD and relative CBF c...
متن کاملFurther Test and Validation of Saturation-recovery T1 MRI Measurement for Imaging Absolute CBF Change
Introduction: The feasibility for imaging and quantifying absolute change of cerebral blood flow (CBF) using saturation-recovery T1 MRI approach has been previously demonstrated using rat ischemia (decreasing CBF) and hypercapnia (increasing CBF) models at 9.4T. Briefly, the water exchange between the capillary and brain tissues through the blood perfusion will affect the apparent water T1, thu...
متن کاملLarge Influence of Flow-related Contribution on fMRI Signal: A 9.4T Study using Hypercapnia
Introduction: The functional MRI (fMRI) method is based on the blood oxygenation level dependence (BOLD) contrast, which is the result of interplay among the CBF, CBV and CMRO2 changes in response to brain stimulation . From the standpoint of NMR physics, BOLD associated with the susceptibility change will affect T2/T2*, in contrast, the perfusion change quantified by CBF and/or inflow effect w...
متن کاملCaffeine-induced uncoupling of cerebral blood flow and oxygen metabolism: A calibrated BOLD fMRI study
Although functional MRI (fMRI) based on blood oxygenation level-dependent (BOLD) signal changes is a sensitive tool for mapping brain activation, quantitative studies of the physiological effects of pharmacological agents using fMRI alone are difficult to interpret due to the complexities inherent in the BOLD response. Hypercapnia-calibrated BOLD methodology is potentially a more powerful physi...
متن کاملMethylene blue potentiates stimulus-evoked fMRI responses and cerebral oxygen consumption during normoxia and hypoxia
Methylene blue USP (MB) at low doses has metabolic-enhancing and antioxidant properties and exhibits experimental neurotherapeutic benefits, but little is known about its in vivo effects on cerebral blood flow (CBF), functional evoked responses, and the associated changes in cerebral metabolic rate of oxygen (CMRO2). This study used magnetic resonance imaging (MRI) to evaluate the in vivo effec...
