| 0–10 mm | 11–20 mm | 21–30 mm | 31–50 mm | ≥51 mm | |
|---|---|---|---|---|---|
| T2W-FSE | 1 (0) | 11 (3) | 10 (2) | 22 (17) | 8 (8) |

Note.—T2W-FSE indicates dual T2-weighted fast spin-echo; T2W-FS-FSE, T2-weighted fat-suppressed fast spin-echo; CE-T1 W-FS-SE, contrast-enhanced T1-weighted fat-suppressed spin-echo; 3D TOF MRA, unenhanced and contrast-enhanced 3D time-of-flight MR angiography; DSA, digital subtraction angiography. Data in parenthesis represent presence of intra-tumoral flow for each subgroup and technique.
