    In an inversion-recovery experiment, at the null point, t0, for a tissue with a short T1 relaxation time, the tissue will:(反转恢复实验中,对于一种T1弛豫时间短的组织的过零点t0,组织会:)
    A: ) have an observable signal, while long T1 tissue will have no signal.(有可以被观测到的信号,长T1的组织没有信号)
    B: ) have no observable signal, while long T1 tissue will have signal.(没有可以观测的信号,长T1的组织会有信号)
    C: ) have a similar signal intensity to long T1 tissue.(和长T1组织有相同的信号)
