Computer-assisted detection has now expanded its focus to helping physicians more effectively view mammography, MRI, ultrasound, CT and x-ray images with an eye toward breast, lung and colon cancer detection. Look for a nice boost to CAD this year in providing connectivity to PACS to smooth department workflow.

Cedara (Booth #1918) is showcasing its Cedara B-CAD application, the world's first CAD for assisting radiologists in analyzing breast ultrasound images. It automatically analyzes, segments, and classifies shape and orientation characteristics of user-selected regions of interest (ROI). It allows quick additions of annotations to DICOM images and automatically generates a report using the ACR BI-RADS Ultrasound Lexicon Classification Form.

B-CAD also can be integrated with I-ReadMammo, Cedara's multimodality breast imaging workstation. As a united offering, Cedara I-ReadMammo with Cedara B-CAD represents a solution for breast imaging workflow through support for multiple FFDM vendors and modalities, specialized tools for mammography reading, CAD marker display and more.

Confirma, Inc. (Booth #8750) is highlighting its CADstream CAD system for magnetic resonance imaging that automates the processing of MRI studies. CADstream's core automated features include image registration, multiplanar reformatting, subtractions, angiogenesis maps, curves, maximum intensity projections (MIPs), volume summaries and SureLoc for real-time interventional guidance. CADstream also incorporates advanced features, including a streamlined portfolio for more comprehensive treatment planning - incorporating the BI-RADS Atlas for lesion classification - and a multimodality-ready configuration, offering users the ability to display and compare mammography, ultrasound and breast MRI studies.

The latest version of CADstream includes an expanded version of SureLoc that calculates coordinates for interventional guidance. SureLoc now reports needle position for both grid and pillar methods in real time (insertion location, depth and needle angle) and displays images and needle position in the patient's orientation. This feature is compatible with interventional breast coils and with vacuum-assisted biopsy systems, and is available on any networked PC for access at any location.

In its initial application, CADstream is being used to assist in the analysis, interventional guidance and reporting of breast MRI studies. CADstream is DICOM 3.0 compliant, allowing integration with any MRI scanner and PACS.

EDDA Technology (Booth #1505) is highlighting its flagship IQQA-Chest v1.0 that debuted at RSNA 2004, as well as showing as a works in progress IQQA-Liver system - both from the  Intelligent/Interactive Qualitative and Quantitative Analysis (IQQA) series of products.

IQQA-Chest is a software system designed for soft-copy reading of digital radiographic chest images that assists physicians in the identification, quantitative evaluation, diagnosis and reporting of pulmonary nodules. EDDA points out that the latest clinical study involving five hospitals in China on CT-confirmed nodules suggested improved performance in detecting lung nodules from screening populations using both DR and CR technology. (The results have been accepted for oral presentation at RSNA 2005.)

EDDA recently released IQQA-Chest v1.1 featuring advanced DICOM connectivity (including DICOM storage, Query/Retrieval, Structured Report and Send) and a refined worklist design to further enhance workflow efficiency.  

IQQA-Liver, which is pending FDA approval (which could come prior to showtime), is geared toward enhancing workflow for the application of dynamic liver imaging that is challenged by data overflow from multislice CT. Namely with 32- and 64-detector CT, the number of slices in a dynamic CT series can easily reach a few thousand, with at least four phases acquired in a typical dynamic CT study with contrast. IQQA-Liver is designed to assist the review of serial multi-phase CT acquisitions of the liver using dynamic imaging techniques. It offers advanced visualization and quantitative evaluation tools empowered by image registration and segmentation techniques and can be used in the diagnosis and staging of primary liver disease and liver metastases as well as in pre-operative assessment. Clinical testing of the system has been conducted in two hospitals in China.
