title: [3-Dimensional model reconstruction of penis and surrounding tissue].
abstract: OBJECTIVE
  To evaluate the feasibility of 3-Dimensional (3-D) model reconstruction of penis and surrounding structures based on magnetic resonance images, which may provide the model building method for modeling surgery of individual penoplasty.
  
  
  METHODS
  Magnetic resonance (MR) images of penis with different imaging parameters were evaluated. With the surface rendering construction, the 3D virtual model was established by Amira software.
  
  
  RESULTS
  The anatomical details imaging is better in T2-weighted fast spin-echo images with 3.0 mm slice thickness. The established model based on the MR images can show the soft-tissue, suspensory ligament of the penis. The suspensory ligament stretches between the pubic symphysis and the corpora cavernosa. The penile roots attach to inferior ramus of pubis.
  
  
  CONCLUSIONS
  MR imaging provides enough anatomical information for modeling. It can be used for the development of model surgery system of individual penoplasty.
