A Linear Least Squares Method for Unbiased Estimation of T1 from SPGR Signals

The longitudinal relaxation time, T(1), can be estimated from two or more spoiled gradient recalled echo images (SPGR) acquired with different flip angles and/or repetition times. The function relating signal intensity to flip angle and TR is non-linear; however, a linear form proposed 30 years ago...
