MRF technique appears to be a promising and rapid quantitative method for the characterization of free water content and tumor morphology in BMs. WebSo, T1 (which is T x 1) is 4.5g x 1 = 4.5g. Therefore to work out –T1 would be 75g (for your pack weight) – T1; 75g – 4.5g = 70.5g. So for this example, to comply with rule 2, that no more than 2.5% of your samples must be –T1, means that – no more than 2.5% of your sample must weigh less than 70.5g.
