Multimodality developer Siemens Medical Solutions has released a new version of its computer-assisted detection (CAD) syngo Colonography Polyp Enhanced Viewing (PEV) application. The software tool helps radiologists to detect polyp-shaped objects between 6-mm and 25-mm in size and can now be used both in clean-prepped and solid-liquid tagged protocols, according to the Malvern, Pa.-based firm.

The company said the latest iteration of syngo Colonography PEV was developed using a database of more than 1,700 CT colonography cases from more than 15 clinical sites worldwide, and covers a variety of computed tomography (CT) acquisition parameters and bowel preparation protocols.

In addition to the PEV tool, Siemens recently introduced its auto-processing feature for CT workflow. The application provides pre-processing technology for oncology, cardiac and acute care imaging, the company said.

For example, data acquired on a Siemens Somatom CT scanner for colon exams is automatically processed off-line as it arrives at a syngo MultiModality Workplace. When the radiologist accesses the exam data using the syngo Colonography CT application, potential lesions are identified and ready for review when the reader accesses the PEV function.

The new syngo Colonography PEV version is available on the syngo MultiModality Workplace 2007C as well as the syngo CT Workplace 2007C, Siemens said.
