The scatter plots demonstrate cerebral perfusion during a standard 3-phase protocol: room air, MH and a recovery phase. Global cerebral VI, FI and VFI did not differ with MH in the normal foetuses (n = 28, p > 0.05). Of the foetuses with borderline small left hearts, the VI, FI and VFI values did not differ significantly in the foetuses that were younger than 28 weeks (a, c, e, n = 12, p > 0.05) but decreased significantly in the foetuses that were older than 28 weeks (b, d, f, n = 16, p < 0.01) using the Games-Howell post hoc test for multiple comparisons after one-way analysis of variance. * Statistically significant change between the baseline and MH values in the foetuses with borderline small left hearts
