Abstract
Objective: To analyze the sensitivity and specificity of magnetic resonance in the detection of prostate cancer. Methods: In this work, a cross-sectional, quantitative study of prostate multiparametric magnetic resonance imaging (RM-rp) was performed, from January to February 2020, in the database of a group of large clinics in the city de Montes Claros - MG and region. 2200 medical records of patients seen at the clinic, aged between 45 and 75 years, were analyzed. The collection involved cases that presented lesions suspected of prostate cancer in the prostate MR-rp using the PI-RADS criterion (with scores between 3-5) and total pre-test PSA present. Results: It can be inferred that the use of MRI associated with PSA ≥4ng / dl increases the reliability of the diagnosis by increasing sensitivity and decreasing cases of false positives. In addition, this association maximizes the benefit of this method as a screening test, as it also decreases possible unnecessary and unwanted iatrogenic costs. Conclusion: RM-rp raises the sensitivity and specificity data when compared to PSA in isolation, but it should not be the first test to be requested, but if there is a change in PSA.
