Acquisition protocols: technical parameters.

T2-weighted imaging (axial, sagittal, coronal planes)
− Field-of-view: 12–20 cm to encompass the entire prostate gland and seminal vesicles
− 3 mm section thickness, 0 mm gap
− In-plane resolution: ≤0.7 mm (phase) × ≤0.4 mm (frequency)
Diffusion-weighted imaging (axial plane)
− Free-breathing spin echo EPI sequence combined with spectral fat saturation is recommended
− Section thickness to match T2WI
− TE: ≤90 ms; TR: >3000 msI
− Field-of-view: 16–22 cm
− In plane dimension: ≤2.5 mm phase and frequency
− At least two b-values should be acquired in three orthogonal directions. If only two b-values are utilised, these should be 50 −100 s/mm2 (low) and 800–1000 s/mm2 (high)
− “High b-value” acquisition with b=1400–2000 s/mm2, depending on achievable quality of SNR
− ADC map calculation: low b-value should be ≥50 s/mm2, high b-value should be >800 s/mm2, up to a maximum of 1000 s/mm2
Dynamic contrast-enhanced MRI (axial plane)
− Fat suppression and/or subtraction is recommended
− 2D or 3D T1 gradient echo (GRE) sequence; 3D is preferred
− Section thickness to match T2WI
− Injection rate: 2–3 ml/s
− TR/TE: <100 ms/<5 ms
− In-plane dimension: ≤2 mm × ≤2 mm
− Temporal resolution: ≤10s(<7s is preferred)
− Pharmacodynamic analysis does not have to be performed
