Background
Prostate cancer is one of the most prevalent malignant neoplasms worldwide,
incidence being higher in older patients2.
It represents the second leading cause of death.
In underdeveloped countries,
most of the tumours are diagnosed in advanced stages,
moment in which therapy success is low2.
Magnetic resonance is a non invasive imaging method for evaluating the prostate gland and surrounding structures.
A multiparametric protocol (mpMRI) allows better detection of clinically significant cancer,
as well as differentiating benign from dormant malignancies.
Its main goals being the reduction of unnecessary biopsies and treatment improvement1.
PI-RADS (Prostate Imaging Reporting and Data System) evaluating system is a guideline for building an structured report,
it is designed to promote global standardization and to limit variations in acquisition,
interpretation and mpMRI reporting 1
Multiparametric resonance indications,
patient prepration and neede clinical information are shown in Table 1
