How should you measure a lesion?

According to the Guidelines

( https://www.acr.org/-/media/ACR/Files/RADS/Pi-RADS/PIRADS-V2.pdf )

“…….report the largest dimension of a suspicious finding on an axial image. If the largest dimension of a suspicious finding is on sagittal and/or coronal images, this measurement and imaging plane should also be reported. If a lesion is not clearly delineated on an axial image, report the measurement on the image which best depicts the finding….”

and use the dominant sequence:

“…. for the PZ, DWI is the primary determining sequence ………and for the TZ, T2W is the primary determining sequence……”
