PIRADS v2



Overall scores from the T2W, DWI &

DCE applied sequentially



Certain sequences are dominant

according to zonal anatomy



PZ:

DWI

is primary determinant



E.g. if the DWI score is 4 & T2W score is 3,

the PI-RADS assessment category should

be 4



TZ:

T2W

is the primary determinant



E.g. if T2W score is 4 & DWI score is 2, the

PI-RADS assessment category should be 4
