Abstract
We evaluated pathological findings in targeted biopsies of PI-RADS4 and PI-RADS5 lesions, and clinical data that could predict those patients with benign findings. A retrospective study was conducted to summarize the experience from a single nonacademic center using cognitive fusion and a 1.5 or 3.0 Tesla scanner. We found a false positive rate of 29 and 3.7% for any cancer in PI-RADS 4 and 5 lesions, respectively. Diverse histologic patterns were observed among target biopsies. At multivariate analysis, size ≤ 6mm and previous negative biopsy were independent predictors of false positive PI-RADS4 lesions. The small number of false PI-RADS5 lesions precluded further analyses. Benign findings are common in PI-RADS4 lesions and most of them do not show obvious glandular or stromal hypercellularity as expected in hyperplastic nodules. Size ≤ 6mm and previous negative biopsy predict a higher probability of false positive results in patients with PI-RADS 4 lesions.
