Computer-aided detection figures prominently in the Siemens Medical Systems booth at this year's RSNA meeting. The company is featuring packages for colon cancer, pulmonary embolism, and lung nodules in several work-in-progress versions. Syngo Lung CAD will offer solid nodule detection — improved over the currently available commercial version — that will use a new CAD Manager to present results on PACS workstations. Syngo PE Detection will distinguish segmental and subsegmental filling defects in CT angiography studies of the thorax. Syngo Colonography PEV includes enhancements in the visualization of flat polyps. Syngo MammoCAD, although validated on the company's Mammomat NovationDR full-field digital mammography system and syngo MammoReport soft-copy reading and reporting workstation, has not yet been approved for sale in the U.S.
