Role of serial multiparametric magnetic resonance imaging in prostate cancer active surveillance

Figure 1 Baseline multiparametric magnetic resonance imaging images of two patients with Gleason score 6 low-risk prostate cancer but with different index of suspicion from multiparametric magnetic resonance imaging. Patient 1 had an IOS of 1 on their baseline MRI scan and Patient 2 had an IOS of 5 on their baseline MRI scan. The mpMRI images shown for each patient are: A: T2-weighted image; B: DCE-parameter overlay (Amplitude); C: Quantitative T2 map; D: ADC map. mpMRI: Multiparametric magnetic resonance imaging; MRI: Magnetic resonance imaging; IOS: Index of suspicion; ADC: Apparent diffusion coefficient; DCE: Dynamic contrast-enhanced.
