Özet

Biparametric Magnetic Resonance Imaging (bpMRI) of the prostate combining both morphologic T2-weightedimaging (T2WI) and diffusion-weighted imaging (DWI) is emerging as an alternative to multiparametricMRI (mpMRI) to detect, to localize and to guide prostatic targeted biopsy in patients with suspicious prostatecancer (PCa). BpMRI overcomes some limitations of mpMRI such as the costs, the time required to performthe study, the use of gadolinium-based contrast agents and the lack of a guidance for management of score 3lesions equivocal for significant PCa. In our experience the optimal and similar clinical results of the bpMRIin comparison to mpMRI are essentially related to the DWI that we consider the dominant sequence for detectionsuspicious PCa both in transition and in peripheral zone. In clinical practice, the adoption of bpMRIstandardized scoring system, indicating the likelihood to diagnose a clinically significant PCa and establishingthe management of each suspicious category (from 1 to 4), could represent the rationale to simplify and to improvethe current interpretation of mpMRI based on Prostate Imaging and Reporting Archiving Data Systemversion 2 (PI-RADS v2). In this review article we report and describe the current knowledge about bpMRI inthe detection of suspicious PCa and a simplified PI-RADS based on bpMRI for management of each suspiciousPCa categories to facilitate the communication between radiologists and urologists.

Abstract

Prostatın biparametrik Manyetik Rezonans Görüntülemesi (bpMRG) hem morfolojik T2-ağırlıklı görüntüleme (T2W) hem de difüzyon ağırlıklı görüntülemeyi (DAG) kombine eden ve kuşkulu prostat kanseri (PKa) hastalarında, prostat kanserini belirleme, lokalize etme ve prostat hedefli biyopsiyi yönlendirmede multiparametrik MRG’ye (mpMRG) alternatif olarak ortaya çıkan bir yöntemdir. BpMRG, mpMRG’nin maliyet, çalışmayı uygulamak için gerekli süre, gadolinyum bazlı kontrast maddelerin kullanımı ve önemli PKa için kuşkulu skor 3 lezyonlarının tedavisini yönlendirememe gibi bazı kısıtlamalarının üstesinden gelmektedir. Deneyimimize göre mpMR’e kıyasla bpMRG ile benzer ve optimal klinik sonuçlar esasen hem transizyonel hem de periferik zonda kuşkulu PKa’nın saptanmasında dominant sekans olduğunu düşündüğümüz DAG ile ilişkilidir. Klinik uygulamada, bpMRG ile standardize edilmiş skorlama sisteminin benimsenmesi, klinik açıdan önemli PKa,’ya tanı koyma olasılığına işaret eder. Her bir kuşkulu kategorinin (1 ile 4 arası) tespiti Prostat Görüntüleme, Raporlama, Arşivleme Veri Sisteminin 2. sürümüne (PI-RADSv2) dayanarak mpMRG’nin güncel yorumlanmasını basitleştirme ve iyileştirme gerekçesini temsil edebilir. Bu derleme makalesinde radyologlar ve ürologlar arasındaki iletişimi kolaylaştırmak için kuşkulu PKa’yı tespite ve her bir kuşkulu PKa’nın tedavisi için bpMRG temelinde basitleştirilmiş PI-RADS’e ilişkin güncel bilgileri bildirmekte ve tanımlamaktayız.
