Table 2. Comparative assessment of T1 mapping at room air, pure O2 and perfusion.
Score = 0 n(%) | Score = 1 n(%) | Score = 2 n(%) | Total n(%) | |
---|---|---|---|---|
T1 | 23 (19%) | 56 (47%) | 41 (34%) | 120 (100) |
ΔT1 | 36 (30%) | 43 (36%) | 41 (34%) | 120 (100) |
Perfusion | 21 (19%) | 44 (41%) | 43 (40%) | 108 (100) |
Severity of abnormal T1 at room air (T1), abnormal T1 reduction with 100% O2 (ΔT1) and perfusion alterations (Perfusion) in a per-zone approach. Note that perfusion imaging was rejected by 2 patients.
