PI-RADS recommendations for mpMRI sequence parameters
| 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 |
Since MRSI is still investigational, PI-RADS does not specify MRSI as standard for mpMRI sequences in prostate cancer diagnosis
