Comparison of the quantitative value acquired by the different cerebral circulation metabolism measurement methods. - Comparison of the quantitative value acquired by the different cerebral circulation metabolism measurement methods.

Between the two measurement methods, each of the CBF, CBV and CMRO2 showed strong correlation. Measured values at the seven measurement points of OEF and CMRO2 had differences over 10% between the two methods. Those differences might be originated from differences of the gas inhalation methods, measurements procedure, image reconstruction parameters and image analysis. Without OEF, obtained regression equations could transform the measured values between the two measurement methods.
