Abstract
In this study, a circulation system was used to measure T(1) values of bovine blood under physiological conditions at field strengths of 4.7, 7 and 9.4 T. Results show that T(1) increases linearly with magnetic field B(0) and can be described with the equation T(1)=129 ms/T B(0)+1167 ms for magnetic field strengths between 1.5 and 9.4 T.
摘要
在本研究中，使用一种循环系统在4.7、7和9.4 T的场强下测量生理条件下牛血的T(1)值。结果表明，T(1)随磁场B(0)呈线性增加，对于1.5至9.4 T的磁场强度，可用方程T(1)=129 ms/T B(0)+1167 ms来描述。
