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. Webvalues of T1, T2, and proton density for three pa-tients are listed in Table 1. In the 21-week-old in-fant, the areas of high signal intensity on the FLAIR images, such as the corona radiata, had greater T1 and T2 values as compared with such low signal intensity areas as the cerebellar peduncle and posterior limb of the internal capsule.
