Abstract :
In this response letter, technical issues raised by the comments concerning determination of arterial input function, cardiac and respiratory related motion artifacts, contrast agent application, and compartmental model fitting in our work are addressed in detail, and a discussion on identifying causes of uncertainty in physiological measurement and how to minimize their contribution is presented.
