1
MRI is crucial for monitoring prostate cancer during active surveillance, offering greater accuracy than PSA testing or biopsy.
-
2
Volume assessment of tumors is more clinically relevant than maximum diameter, reflecting tumor burden and growth rate.
-
3
The PRECISE system standardizes reporting of tumor changes but lacks quantification of change magnitude and rate.
-
4
A practical reporting approach emphasizes consistent volume measurement and longitudinal context for better clinical interpretation.

5
MRI's effectiveness in prostate cancer monitoring is enhanced by assessing changes over time and integrating clinical data.
