3-Dimensional model reconstruction of penis and surrounding tissue / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>MR imaging provides enough anatomical information for modeling. It can be used for the development of model surgery system of individual penoplasty.</p>
