Table 1 Comparison of Image Quality and Vessel Contrast Scores for each time point between BPA MRA (gadofosveset trisodium) and ECA MRA (gadopentetate dimeglumine) for the symptomatic arm

From: Comparison of blood pool and extracellular gadolinium contrast for functional MR evaluation of vascular thoracic outlet syndrome

Time Point Contrast Image Quality p-value Vessel Contrast p-value
1. Abduction-early BPA 4.58±0.39 0.92 3.97±0.12 0.57
  ECA 4.50±0.41   3.92±0.19  
2. Abduction-late BPA 4.36±0.38 0.06 3.97±0.12 0.007
  ECA 4.12±0.30   3.73±0.26  
3. Adduction-early BPA 3.89±0.65 0.014 3.42±0.52 <0.001
  ECA 4.42±0.11   3.96±0.14  
4. Adduction-late BPA 4.17±0.49 0.09 3.86±0.29 0.18
  ECA 3.77±0.78   3.62±0.68  
  1. Image Quality Scores: 1=non-diagnostic, 3=diagnostic, 5=excellent Vessel Contrast Scores: 1=same as muscle, 4=much brighter than muscle. Note arterial contrast was assessed at Time Points 1 and 3, and venous contrast at Time Points 2 and 4
