Table 2 Inter-observer flow coefficients of variation, by field strength and vessel type

From: Foetal blood flow measured using phase contrast cardiovascular magnetic resonance – preliminary data comparing 1.5 T with 3.0 T

  Coefficient of variation (%)
B0 (T) MPA AAO SVC AD DAO PBF UV
1.5 8 5 16 13 4 34 7
3.0 4 10 11 9 10 11 14
  1. B0: field strength; MPA: main pulmonary artery; AAO: ascending aorta; SVC: superior vena cava; AD: arterial duct; DAO: descending aorta; PBF: pulmonary blood flow; UV: umbilical vein.
