Background
Prostate cancer is the most commonly diagnosed male cancer, becoming the 2nd leading cause of death in males in the United States. In current practice, diagnosis is achieved via PSA levels and digital rectal examination, and confirmed with US-guided transrectal biopsy. Limitations to this practice include low specificity, detection of clinically insignificant cancers, under detection of clinically significant ones, and overlooking disease extension. Because of this, prostate MRI has become important in the assess prostate cancer by improving detection of clinically significant cancer, which is critical for reducing mortality, and increasing confidence in benign lesions and dormant malignancies, which are not likely to cause morbidity in a man’s lifetime. This reduces unnecessary biopsies and treatment12. To achieve consistency in reporting and interpreting prostate MRIs, a score system known as PI-RADS was created, currently on version 2.1, allowing radiologists to easily communicate classifications of prostate lesions (Fig. 4).
