Hypothesis
This study aimed to assess the positive predictive value (PPV) of high-grade PI-RADS v2.1 MRI findings and their correlation with histopathological results from biopsies.
Conclusion
High-grade PI-RADS v2.1 scores exhibit strong positive predictive value for detecting prostate cancer.
Supporting Evidence
- The PPV was 94.5% for a PI-RADS v2.1 score of 5 and 51.5% for a score of 4.
- Significant correlations were observed between MRI characteristics and high-grade PI-RADS scores.
- Lesions with ill-defined margins were more likely to be prostate cancer compared to those with well-circumscribed borders.
Takeaway
Doctors used special MRI scans to find out if men have prostate cancer, and they found that high scores on these scans usually mean cancer is present.
Methodology
A facility-based cross-sectional study was conducted involving patients referred to the SPHMMC interventional radiology unit with high-grade PI-RADS v2.1 MRI findings who underwent TRUS-guided prostate biopsy.
Potential Biases
MRI findings and histopathology results were reported by different physicians, potentially introducing inter-reader variability.
Limitations
The study focused solely on patients with PI-RADS v2.1 scores of 4 and 5, restricting the analysis to positive predictive value, and potential inter-reader variability in MRI findings and histopathology results.
Participant Demographics
Participants' ages ranged from 46 to 92 years, with the majority (67.6%) being between 61 and 80 years old.
