What is it about?
Pulmonary vein stenosis is an uncommon condition with significant morbidity in children that is frequently diagnosed with CT. We displayed the 3D CT images using our homegrown stereoscopic 3D display system. We tested 24 physicians and compared their diagnostic accuracy for pulmonary vein stenosis for 3D display vs. conventional flat screen display. Our study found that overall, there was no significant difference between the two forms of display for diagnostic accuracy , however, for complex cases, there was an improvement when using 3D stereoscopic display.

Why is it important?
There has been a tremendous increase in three-dimensional (3D) technology in the non-medical and more recently, medical communities. Computed tomography imaging is widely used and easy to translate into 3D technology such as printing and virtual reality. Although there are numerous publications about the use of 3D printing and its applications, there is still relatively little information about virtual reality display and their usefulness in medical practice. The finding that 3D display is useful for more complex cases but not diagnosis in general will help guide further studies into the use of 3D displays for complex medical diseases.
Perspectives
The study results are helpful in guiding where we should focus our efforts on 3D technologies in medicine. As shown, we don't need 3D displays for simple cases, but they are helpful for complicated cases. These results are completed supported by our longstanding clinical work, and it is good to see our experience supported by objective data.
