Table 2.
Comparison of feasibility and artifact rate in Group 1 and Group 2.
| N° | Feasibility n (%) | Breath n (%) | SM n (%) | Ca n (%) | S/N n (%) | CD n (%) | |
|---|---|---|---|---|---|---|---|
| GROUP 1 Segments | 1310 | 1229 (94%) | 11 (13%) | 13 (16%) | 54 (67%) | 3 (4%) | - |
| GROUP 2 Segments | 1342 | 1303 (97%) | 13 (33%) | 10 (26%) | 14 (36%) | 2 (6%) | - |
| P | - | 0.0001 | NS | NS | 0.0001 | NS | - |
Breath: artifacts due to breath/chest movement; SM: slice misalignment due to heart rate variability or premature beat during the scan; Ca: blooming artifact due to large calcifications; S/N: impaired image signal/image noise ratio; CD: cardiac device.
