Table 1 Image quality and artefact scores for the 2D reference and 3D 5× k-t SENSE images before and after contrast.

From: Measurement of left ventricular dimensions with contrast-enhanced three-dimensional cine imaging facilitated by k-t SENSE

  Median Image Quality Score Median Artefact Score
2D reference images 5 0
3D 5× k-t pre-contrast (p value vs 2D reference score) 3 (p < 0.01) 2 (p < 0.01)
3D 5× k-t post-contrast

  1. Legend for Table 1
  2. Image quality scoring: (1) endocardial border not visible (non-diagnostic image), (2) severe blurring of endocardial border, (3) moderate blurring, (4) mild blurring, (5) well defined endocardial border (modified from McConnell et al [13])
  3. Artefact scoring: (0) no artefact, (1) minor artefact, (2) significant artefact but not affecting endocardial border definition, (3) significant artefact obscuring endocardial border in places
