Comparison among tumour subtypes. Apparent diffusion coefficient (ADC) derived from turbo field echo with diffusion-sensitized driven-equilibrium (a) in prolactin-producing tumours (PRL) (2.04 ± 0.76 × 10−3 mm2 s−1) is higher than that in growth hormone-producing tumours (GH) (1.26 ± 0.47 × 10−3 mm2 s−1; p < 0.05) and non-functioning tumours (NON) (1.33 ± 0.42 × 10−3 mm2 s−1; p = 0.04). There is no statistically significant difference between GH and NON (p = 0.97). The T2 weighted images (rT2) (b) in PRL (1.42 ± 0.24) is higher than that in GH (0.94 ± 0.06; p < 0.0001) and NON (1.16 ± 0.11; p < 0.05). The rT2 in NON is also significantly higher than that in GH (p = 0.02). There are no statistically significant differences in T1 weighted images (rT1) (c) among tumour subtypes; NON (1.17 ± 0.09), GH (1.10 ± 0.14) and PRL (1.06 ± 0.04; p > 0.05). n.s., not significant.
