Table 2.
SRR Quality and Number of Stacks Used per Case.
| Case | Sequence for SRR | Slice rejection, mean ± SD (range) | No. of stacks for SRR | SRR quality a |
|---|---|---|---|---|
| 1 | T2 HASTE | 1 ± 1 (0-2) | 5 | 1.5 |
| 2 | T2 HASTE | 3 ± 4 (0-10) | 8 | 0.7 |
| 3 | T2 HASTE | 1 ± 1 (0-3) | 8 | 1.5 |
| 4 | T2 HASTE | 4 ± 3 (0-6) | 4 | 0 b |
| 5 | T2 HASTE | 3 ± 2 (0-7) | 9 | 0.3 |
| 6 | TRUFI | 0 ± 1 (0-1) | 3 | 0 b |
| 7 | T2 HASTE | 7 ± 4 (2-15) | 11 | 1.5 |
Abbreviations: SRR, super-resolution reconstruction; T2 HASTE, T2 half-Fourier acquisition single-shot turbo spin echo; TRUFI, true fast imaging with steady state–free precession.
a
Average obtained across 3 radiologists whereby 0 = lots of artifact/blur, 1 = little artifact/blur, and 2 = no artifact/blur.
b
Fewer than 5 stacks are typically insufficient for obtaining good SRR quality.
