英文摘要 | It has recently been shown that O-17 magnetic resonance (MR) spectroscopic imaging at ultrahigh fields provides a reliable method for measuring CMRO2 during a short period of O-17(2) gas inhalation. The mathematical (or complete) model used in the O-17 MR method for calculating CMRO2 requires simultaneous measurements of multiple parameters including the concentration of H-2 O-17 produced in the brain tissue from inhaled O-17(2) gas (C-b), CBF, and the input Junction for the H-2 O-17(2) concentration in the feeding artery (C-a). Both invasive and noninvasive measurements are involved in determining all of these parameters. In this article, two simplified methods are proposed and validated for calculating CMRO2 based on O-17 MR measurement(s); the first method requires the measurements of C-b and CBF, but not C-a, and the second method only requires a single noninvasive measurement of C-b. The simplified methods were used to calculate CMRO2 in anesthetized rat brain, and the results were compared with those obtained using the complete model. The results from this work show (1) the validity of the simplified methods for quantifying CMRO2, and (2) the feasibility for establishing a completely noninvasive O-17 MR approach for imaging CMRO2 in vivo. |
