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

<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>

Imaging diagnosis of the vertebral injury in earthquake / 中国骨伤

<p><b>OBJECTIVE</b>To explore the clinical value of imaging diagnosis of the vertebral injury in earthquake.</p><p><b>METHODS</b>Twenty-two cases of the vertebral injury in earthquake with clinical and imaging data were analyzed retrospectively. All of the cases were performed X-ray plain film examination, CT in 20 cases and MRI in 15 cases.</p><p><b>RESULTS</b>Imaging examination can establish definitive diagnosis in all cases. In the 22 cases, the vertebral compression fracture was found in 20 cases, and vertebral bursting fracture in 2 cases,single-level vertebral fracture in 12 case,and multiple-level vertebral fracture in 10 case. Among the 31 vertebral bodies of fracture, the fracture of cervical vertebra, thoracic vertebra, lumbar vertebra and sacral vertebra was found in 3, 12, 14, 2 vertebral bodies, respectively.</p><p><b>CONCLUSION</b>Imaging examination is the most valuable examination method in diagnosis of the vertebral injury in earthquake. It can not only make definitive diagnosis, but also play an important role in selection of therapeutic method.</p>
