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
