This study was to evaluate the abilities of T1ρ and ADC to estimate the duration of ischemia in human, and focus on clinical application. We take a cross-sectional study to collect patients with brain ischemia in period of time(March 2014 to February 2015), and exploit the characteristics of ADC and T1ρ in brain ischemia in various stages of ischemia and uncover their relationships with ischemia stages. Our results indicate that T1ρ parametric results were elevated in the ischemic lesion, and increased over time of ischemia in a linear fashion.
