The goal of the Casimage project is to offer an authoring and editing environment integrated with the Picture Archiving and Communication Systems (PACS) for creating image-based electronic teaching files. This software is based on a client/server architecture allowing remote access of users to a central database. This authoring environment allows radiologists to create reference databases and collection of digital images for teaching and research directly from clinical cases being reviewed on PACS diagnostic workstations. The environment includes all tools to create teaching files, including textual description, annotations, and image manipulation. The software also allows users to generate stand-alone CD-ROMs and web-based teaching files to easily share their collections. The system includes a web server compatible with the Medical Imaging Resource Center standard (MIRC, http://mirc.rsna.org) to easily integrate collections in the RSNA web network dedicated to teaching files. This software could be installed on any PACS workstation to allow users to add new cases at any time and anywhere during clinical operations. Several images collections were created with this tool, including thoracic imaging that was subsequently made available on a CD-Rom and on our web site and through the MIRC network for public access.

outpatient clinic based TPLA procedures were performed successfully and discharged the same day. The ablation zone on T2-weighted, DCE and CEUS imaging and histology (figure 1) was clearly demarcated upon qualitative analysis and the 3D shape seems to be ellipsoid on MRI and CEUS. This closely matches the annotated ablation zone on histology. Currently, quantitative data, regarding 3D segmentation of T2-weighted, DCE, CEUS and histopathology, is being analyzed to be presented.CONCLUSIONS: TPLA is a feasible office-based minimal invasive focal treatment of PCa and it can be performed safely under local anesthesia, in these preliminary results. Multiple laser fiber configurations will be investigated with ongoing enrollment. The ablation zone is clearly demarcated on CEUS imaging and on MRI T2-weighted and DCE imaging. The histopathological defined 3D ablation zone closely matches the ablation zone seen on imaging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
