Anatomical images of a pregnant mouse showing multiple feto-placental units. F marks the fetuses and the white arrows their placentas. (A) A 2D fast spin-echo (FSE) image. (B) A 2D SPEN image. (C) A 2D SE-EPI image. (D and E) Signal-to-noise ratio of SPEN and SE-EPI images on embryonic days 14.5 (D) and 18.5 (E) (mean ± SEM; *P < 0.05). Scanning parameters: 1 mm slice thickness, field of view (FOV) = 40 × 40 mm2, and in-plane resolution = 0.1563 mm (A) and 0.4 mm (B and C). Both 2D SPEN and SE-EPI data were collected with one segment and reconstructed with no zero filling. Only 50% of the EPI images succeeded in supplying usable data (additional SPEN and SE-EPI MRI data can be found in Fig. S1).
