Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Current assessment of lower limb ischemia cannot reflect the location and degree of ischemia. Tissue perfusion assessment was used in the diagnosis and treatment of lower limb ischemia in this project, and the quantitative evaluation of ischemia degree was realized by using its advantages of quantitative analysis and perfusion imaging.
