Magnitude of improvement in subjective image quality assessment (SD)
| Angiogram type | Number of images | Early phase | Mid-phase | Late phase |
|---|---|---|---|---|
| Scale: Grade 0 means that both images were of equal quality. For each image pair we determined if one image was mildly (grade 1), moderately (grade 2), or highly superior (grade 3) *p<0.05 in one paired Student t test comparing to null hypothesis. **p<0.01 in one paired Student t test comparing to null hypothesis. ***p<0.001 in one paired Student t test comparing to null hypothesis. | ||||
