The role of computer-aided 3-dimensional analytic tools and virtual microscopy in the investigation of radiologic-pathologic correlation.

Abstract

To cope with recent advances in radiologic imaging technology, a corresponding method for pathomorphologic demonstration should be developed to promote better understanding of radiologic-pathologic correlation. We attempted to obtain gross and microscopic images by using a 3-dimensional analytic tool and virtual microscopy and to link these images with multidetector computed tomography images. Surgically resected specimens were sliced to a thickness of 3 mm, and the digital images of each slice were 3-dimensionally reconstructed with RATOC TRI/3D SRF II software. Histology slides were digitized by using virtual microscopy with an Olympus VS-100. We obtained clear gross pathologic images in arbitrary cut sections of organs, and it was possible to rotate these 3-dimensional images at any angle. Furthermore, we created synchronous cut-section movies of computed tomography and gross pathologic images. Subsequently, we switched from these cut-section movies to virtual microscopy images by clicking on the hyperlink button to observe radiologic-pathologic correlation.
