Paired transverse images of the four cardiac chambers in a foetus at 19 weeks gestation, obtained 6 days after termination of pregnancy. Post-mortem ultrasound image (a) and T2-weighted MRI at 1.5T (b) both show a small ventricular septal defect (dotted white arrow). It is also interesting to note the normal ‘expected’ post-mortem intra-cardiac clot (echogenic material on ultrasound, low signal on MRI) and fluid (hypoechoic on ultrasound, high signal on MRI)
