Assessment of likelihood of radiological change on magnetic resonance imaging in patients on active surveillance for prostate cancer (PRECISE score)

PRECISE score	Assessment of likelihood of radiological progression
1	Resolution of previous features suspicious on MRI
2	Reduction in volume and/or conspicuity of features suspicious for prostate cancer
3	Stable MRI appearance: no new focal/diffuse lesions
4	Significant increase in size and/or conspicuity of features suspicious for prostate cancer
5	Definite radiologic stage progression (ECE, SV involvement, LN involvement, metastasis)

MRI magnetic resonance imaging, ECE extracapsular extension, SV seminal vesicle, LN lymph node
