October 30, 2008 – Definiens is developing computer-aided detection (CAD) applications for the 3D and 4D medical imaging field, Definiens LymphExpertT, designed to help radiologists rapidly and accurately identify and track lesions of interest, facilitating earlier detection and personalized treatments.

Definiens will introduce Definiens LymphExpertT at RSNA 2008. The new application is designed to help radiologists analyze lymph nodes, providing volumetric insight and time modeling functions.

According to the World Health Organization, cancer is the second-leading cause of death in the world and accounted for 7.6 million deaths worldwide in 2005. Advancements in medical imaging systems (e.g., CT, MRI, PET) promise earlier detection and treatment, promoting survival rates. However, prevalent use of medical imaging has led to a dramatic increase in the volume of images to be analyzed, resulting in higher workloads and logistical bottlenecks for clinical radiologists.

Definiens CAD applications will support radiologists in the collection of diagnostic data, reducing human error due to fatigue or data overload. The applications utilize contextual information to compare images from different modalities and over time in a consistent and reproducible manner. Definiens’ applications can be implemented in standard medical imaging systems to provide automated volumetric measurements of almost all structures, including organs and lesions.

Current measurement criteria, such as RECIST for tumors, employ only one-dimensional measurements. Definiens' CAD applications are specifically designed to measure and track tumors volumetrically and over time, producing highly accurate assessments of tumor size and growth. This will allow radiologists to make earlier, more informed judgements on the efficacy of treatments and whether to continue or alter treatment options.

The company says its new applications will enable radiologists to analyze and track lymph nodes of interest in an accurate and consistent manner.
