Polyp-Enhanced Viewing Developed for CT Colonography Examinations

Siemens Medical Solutions (Erlangen, Germany) has recently released a new version of the syngo Colonography PEV (Polyp-Enhanced Viewing) system. With the new version, syngo Colonography PEV provides the benefits of computer-assisted diagnostic (CAD) reading to a wider range of protocols commonly applied in computed tomography (CT) colonography today, including stool-tagging agents. The PEV tool is integrated into the syngo Colonography CT application.

Together with workflow-enhancing features such as Auto Polyp Measurements, the software improves reading accuracy as well as efficiency. The system was developed using an extensive database of more than 1,700 CT colonography cases from more than 15 clinical sites worldwide, and covers a variety of CT acquisition parameters and bowel preparation protocols.

Increased colorectal cancer screening is creating a demand for tools that improve speed, enhance confidence, and offer our patients the highest possible level of care, said Dr. Anno Graser, Klinikum Grosshadern (Munich, Germany). The PEV solution from Siemens represents a valuable support mechanism for detecting polyps, especially in the important 5-9 mm size range, which require a high level of sensitivity and are critical during early diagnosis.

In addition to the PEV tool, Siemens recently introduced its auto-processing feature. With its pre-processing technology for oncology, cardiac, and acute care imaging, this feature is helping radiologists to obtain critical images when and where needed to make faster and more efficient diagnostic decisions. In the field of oncology, data acquired on a Siemens Somatom CT scanner for colon exams is automatically processed off-line as it arrives at the 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 first version of syngo Colonography PEV was launched in February 2006 as one of the first automated detection systems for use in CT colonography, and the upgraded version is available on the syngo MultiModality Workplace 2007C as well as the syngo CT Workplace 2007C. Siemens has shipped more than 300 units of syngo Colonography PEV worldwide.
