Fig. 2From: Perinatal post mortem ultrasound (PMUS): a practical approachTwo transverse postmortem ultrasound images of the chest in the same 23-week gestational-aged foetus, obtained 4 days after death. Postmortem ultrasound performed outside the water bath (a) and with foetus in the water bath (b). Notice how the thoracic cage was collapsed both due to body laxity and transducer compression in image (a), but how there is improved visualisation of the heart (asterisk) and lungs (white arrows) using the water bath (b) as the chest expandsBack to article page
