title: [Four-dimensional reconstruction by inversion mode of spatio-temporal image in prenatal diagnosis of congenital heart diseases].
abstract: OBJECTIVE
  To investigate the value of 4-dimensional reconstruction by inversion mode of spatio-temporal image correlation (STIC) in prenatal diagnosis of congenital heart diseases.
  
  
  METHODS
  Cardiac volume images of 30 normal fetuses and 22 fetuses with congenital heart diseases were obtained by STIC gray-scale 2-dimensional imaging technique. Under the guidance of cross-sectional display, the images were collected by inversion mode.
  
  
  RESULTS
  A total of 53 and 38 qualified volume images were obtained in the 30 normal fetuses and 22 fetuses with congenital heart diseases respectively. All volume images were inverted successfully and showed the spacial position of the heart and blood vessel directly.
  
  
  CONCLUSIONS
  Four-dimensional reconstruction by inversion mode of STIC is feasible. This new method can provide more morphologic information, and may be used for prenatal diagnosis of congenital heart diseases.
