Workflow Software Supports Multidisciplinary Liver Imaging Evaluations

New imaging workflow software provides a novel toolset for real-time interactive assessment and volumetric quantification of liver, liver lobes, hepatics lesions, and vessels. With the intuitive and easy-to-use tools, physicians may in real-time perform virtual simulation of resection, lobular/segmental/vascular manipulation and quantification to achieve desired planning result typically within minutes.

Edda Technology (Princeton, NJ, USA) announced that the number of clinical cases evaluated for pre- and post-operative assessment using IQQA-Liver in hospitals has exceeded 1,000 examinations, since the first commercial system installation in Q2 2009. IQQA-Liver, now marketed worldwide, is a comprehensive workflow solution supporting modern multidisciplinary liver imaging evaluation and management.

Primary liver cancer represents one of the most common malignancies worldwide and accounts for almost 1.25 million deaths yearly. In the United States, liver disease is among the 10 major causes of death. The management of hepatic tumors presents a challenging problem. Advanced preoperative imaging assessment is vital in determining appropriate treatment, and requires the participation of a multidisciplinary team of surgeons, oncologists, hepatologists, and interventional radiologists specializing in liver malignancy.

IQQA-Liver is designed to cope with such a challenge. Edda's proprietary information technology (IT) allows enterprise-wide deployment of IQQA-Liver via web so as to rapidly share data and results anywhere anytime among the multidisciplinary liver team.

IQQA-Liver has clearance by the U.S. Food and Drug and Demonstration (FDA), China SFDA, Taiwan DOH, and carries the CE marking. It is currently in use at numerous prestigious liver transplantation/surgery/interventional centers worldwide, including University of Colorado Hospitals Denver (USA), and in China, Shanghai Zhongshan Hospital, Shanghai Ruijin Hospital, Tianjin First Center Hospital, Beijing You'an Hospital, and Nanjing Gulou Hospital.

In one study, University of Colorado Hospital Denver employed IQQA-Liver to evaluate retrospectively the entire living liver donor (LLD) candidate studies rejected in a two-year period, and found that about 48% that were previously rejected due to anatomic abnormalities by conventional computed tomography (CT) visualization could have favorable anatomy for LLD. According to Dr. Igal Kam, chief of transplantation, and Dr. Paul Russ, professor of radiology, "IQQA-Liver allows for better understanding of surgical anatomy and surgical planning in the preoperative evaluation. This will have positive outcome on available livers and LLD selection.” Results will soon be presented at the 23rd International Congress of the Transplantation Society in Vancouver (BC, Canada).
