Table 1. Placental visibility as rated by a blinded reader (trained maternal-fetal radiologist).

Placenta Visibility	Number observed with Conventional Gd (Multihance)	Number observed with Liposomal Gd (NMRX)
1	1	1
2	6	7
3	25	17
4	15	21
5	7	1

The Chi-squared test on the score distributions indicated a probability of 2 × 10⁻⁸, testing the null hypothesis that the two distributions are different, suggesting that the two contrast agents yielded equivalent images.
