Software Developed for Fast Volumetry Assessment for MDCT of the Liver

New characterization software for the liver is designed to assist in the physician's fast assessment of volumetry from multidetector computed tomography (MDCT) imaging.

Edda Technology, Inc. (Princeton, NJ, USA) announced the launch of its new release of IQQA-Liver V1.2, which was featured at the annual meeting of the Association for Medical Imaging Management (AHRA) in Denver, CO, USA, in July 2008.

The rapid developments of MDCT technology enhance its abdominal imaging applications. MDCT is playing an increasingly important role not only in characterization of liver and liver lesions, but also in preoperative assessment for live resection and transplantation. To fully realize the value of MDCT scans, quantitative assessment of anatomic volume is mandatory. However, delineation and measurement of various volumes via manual tracing on image slices poses tremendous stress on workload, and suffers from significant inconsistency due to inter- and intraobserver variations.

The new release of IQQA-Liver focuses on real-time assistive tools and automated workflow for the physician's fast assessment of volumetry of liver, liver lesions, vascular structures, liver segments, and lobes from MDCT. Such automated workflow is based upon sophisticated image analysis algorithms and the real-time interactive design. The system performs automatic anatomic phase registration to allow simultaneous visualization and easy cross-referencing of lesion location and characteristics across the different phases. IQQA-Liver additionally provides automated segmentation tools and additional multiple real-time tools for users to interactively separate and label specific liver segments and lobes in three dimensions (3D). Quantitative measurements are extracted from segmented and labeled volumes instantly.

"Edda strives to provide a new generation of interactive decision/planning aid solutions to physicians for daily clinical practice,” stated Dr. Jian-Zhong Qian, president and CEO of Edda Technology. "Our innovation is for the confidence of both physicians and patients when it comes to accurate and fast information assessment from medical imaging.”

IQQA-Liver has been in clinical use in several Chinese hospitals for liver cancer detection, diagnosis, and preoperative evaluation purposes, including Eastern Hepatobiliary Surgery Hospital in Shanghai, and Shanghai Ruijin Hospital. The system can be readily deployed onto existing hospital picture archiving and communication systems (PACS) workstations with Edda's proprietary IQQA Enterprise Engine technologies.
