The image processing board was used to drastically reduce the computation time required for 3D image-data rotation. The trackball was used as a 3D pointing device, able to interactively and intuitively determine the 3D view direction. Windows-events generated by the rotation of the trackball were coded to operations which rotated the 3D object. The 3D object was then displayed as a volume rendered image. In conclusion, the proposed system is very useful in understanding 3D structures of volume data.
Acute scrotum is characterized by the sudden onset of symptoms such as pain, swelling, and redness.
This condition includes various pathology, such as testicular torsion, testicular rupture, acute epididymitis, acute orchitis, and appendiceal torsion. It is imperative to differentiate testicular torsion and testicular rupture, both of which require an immediate surgical approach, from other conditions that can be treated with conservative therapy. Although a combination of color Doppler US and radionuclide scintigraphy has been the basis to assess testicular perfusion, it is not always accurate. MR imaging including dynamic contrast-enhanced subtraction can provide information about both testicular morphology and blood flow, based on the contrast enhancement pattern. In this study, dynamic contrast-enhanced subtraction MR images were obtained with a circular surface coil.
