Computer-aided detection (CAD) developer R2 Technology has launched a pulmonary artery patency exam (PE) tool.
Designed to help physicians detect potential pulmonary artery obstructions or filling defects such as emboli or tumors during multislice CT exams, the tool examines patency following a multislice CT pulmonary angiogram, according to the Sunnyvale, CA-based vendor. It then performs an anatomical segmentation process, providing automatic calculations of vessel diameter, percent occlusion, and size of the detected obstruction, R2 said.
The tool is available with version 2.0 of R2's CT Lung CAD system.
