Biparametrik Prostat MRG, Multiparametrik MRG ile Prostat Kanseri Tespiti İçin Benzer Tanısal Doğruluk Oranları Gösterir

Abstract

Amaç: Prostat kanseri tanısında bp-MRG'nin tanısal doğruluğunu standart mp-MRI ile karşılaştırmak. Gereç ve Yöntemler: 3 Tesla MRG cihazında elde edilen bp-MRG bulguları mp-MRG bulguları ile karşılaştırmalı olarak retrospektif olarak değerlendirildi. Bp- ve mp-MRG'ler için duyarlılık, özgüllük, pozitif ve negatif prediktif değerler (PPV ve NPV) hesaplandı ve karşılaştırıldı. Bulgular: Ortalama yaşı 62.4±11.8 yıl (31-86 yıl aralığında) olan toplam 202 hasta dahil edilme kriterlerini karşıladı. PI-RADS 4 ve 5 lezyonlu hastalarda; bp-MRG ve mP-MRG için duyarlılık, özgüllük, PPV, NPV sırasıyla %95.4, %77.2, %53.8, %98.3 ve %97.7, %73.4, %50.5, %99.1 idi. Sonuç: PI-RADS 4 ve 5 lezyonları için tanısal doğruluk oranları bp-MRI ve mp-MRI için benzer bulundu.

Biparametric Prostate MRI Shows Similar Diagnostic Accuracy Rates for Prostate Cancer Detection with Multiparametric MRI

Abstract

Objective: To compare the diagnostic accuracy of bp-MRI with standard mp-MRI in the diagnosis of prostate cancer. Material and Methods: We retrospectively evaluated the bp-MRIs in comparison with mp-MRIs at 3 Tesla. Sensitivity, specificity, positive and negative predictive values (PPV and NPV), for bp- and mp-MRIs were calculated and compared. Results: A total of 202 patients with a mean age of 62.4±11.8 years (range from 31 to 86 years) fulfilled the inclusion criteria. In patients with PI-RADS 4 and 5 lesions; the sensitivity, specificity, PPV, NPV for bp-MRI versus mp-MRI were 95.4%, 77.2%, 53.8%, 98.3% and 97.7% vs 73.4%, 50.5%, 99.1%, respectively. Conclusion: Overall diagnostic accuracy was similar for the bp-MRI and the mp-MRI for PI-RADS 4 and 5 lesions.
