“…Therefore, rapid prototyping may have significant implications for in-utero fetal MR imaging, particularly in understanding the exact relations of the internal organs in cases of complex anomalies such as fetal diaphragmatic hernias and conjoined twins [12], which may allow planning of subsequent surgical management in such fetuses in the future. In addition, facial models created by rapid prototyping of in-utero MR, may be useful in identifying facial dysmorphism in cases of genetic syndromes and allow clear demonstration of the extent of facial clefting.…”

ObjectivesThe recent decline in autopsy rates and lack of human anatomical material donated for research and training has resulted in issues for medical training in the United Kingdom. This study aims to examine the feasibility of making accurate three-dimensional (3D) models of the human body and visceral organs using post-mortem magnetic resonance (MR) imaging and rapid prototyping.MethodsWe performed post-mortem MR imaging using a 3D T2-weighted sequence in 11 fetuses and infants, before autopsy, using either a 1.5-T or 9.4-T MR scanner. Internal organs were reconstructed in silico and 3D models were created by rapid prototyping.ResultsThe median gestation of fetuses was 20 (range 19–30) weeks and the median age of infants was 12 (range 8–16) weeks. Models created by rapid prototyping accurately depicted structural abnormalities and allowed clear visualisation of 3D relationships.ConclusionsAccurate 3D modelling of anatomical features from post-mortem imaging in fetuses and infants is feasible. These models could have a large number of medical applications, including improved parental counselling, invaluable teaching resources and significant medico-legal applications to demonstrate disease or injury, without the need to show actual autopsy photographs.

“…Imaging took the form of CT, CT angiography, MRI, and Digital subtraction angiography (DSA) 7 3D stereolithographic models were constructed to aid data interpretation and facilitate detailed planning. 8,9 The twins showed no neurological abnormalities. Twin 1 was of normal weight, hypotensive and produced low volumes of urine, whilst twin 2 was underweight, hypertensive and produced high volumes of urine.…”

“…RP models have proven to be extremely successful aids to diagnosis and planning for complex surgical cases. For example models are routinely used in planning the separation of conjoined twins [4]. Many applications are therefore created from individual patient data.…”
