Table 1 PI-RADS recommendations for mpMRI sequence parameters

From: Trends in targeted prostate brachytherapy: from multiparametric MRI to nanomolecular radiosensitizers

Imaging sequence Slice (mm) FOV (cm) In-plane dimensions (mm) TR/TE (msec) Additional Contrast
T2W 3 12–20 ≤0.7 × ≤0.4 Not specified
DWI ≤4 16–22 ≤2.4 × 2.5 ≤90/ ≥3000 b min = 50–100 s/mm2
b max = 800–1000 s/mm2
DCEI 3 Entire prostate + SV ≤2 × 2 <100/ <5 Observation time ≥2 min 0.1 mmol/kg GBCA; injection rate = 2–3 cc/sec
  1. Since MRSI is still investigational, PI-RADS does not specify MRSI as standard for mpMRI sequences in prostate cancer diagnosis
