As more emphasis continues to be placed on the early detection of cancer, vendors are touting computer aided detection (CAD) software as the "second pair of eyes" to assist physicians to identify, segment, measure and analyze suspicious pathology. At RSNA, it was apparent that vendors are working hard at developing the CAD technology needed for a variety of imaging modalities, including mammography, breast ultrasound and MRI, CT colonography and lung CT.
Enhancements to systems at the show focused on making CAD more user-friendly and easy to integrate into day-to-day workflow. CAD is not only for the identification and evaluation of lesions of interest, but available with comprehensive editing and evaluation tools that bridge diagnostic decisions with treatment planning.
3TP Imaging Sciences announced it changed its name to CAD Sciences. CAD Sciences' CAD products use a proprietary Full-Time-Point analysis algorithm (fTP) that offers robust reporting and streamlined workflow capability.
Cedara, a Merge Healthcare company, announced the market release of Cedara B-CAD 1.0 to assist radiologists in the analysis of solid breast nodules via ultrasound by automatically analyzing, segmenting and classifying shape and orientation characteristics of user-selected regions of interest. B-CAD automatically generates a report using the ACR BI-RADS ultrasound lexicon classification form, Cedara says.
Kodak's Health Group is distributing the system as part of an integration with the Kodak Carestream mammography workstation.
Confirma at RSNA highlighted new features, products and options to CADstream CAD software for breast MRI studies. The company announced an expanded version of SureLoc, CADstream's interventional guidance tool, that is now compatible with all interventional guidance equipment.
CADalog, a new feature on CADstream, provides storage and timely access to CADstream studies saved with a CADalyst user interface, as well as studies available for on-demand retrieval, Confirma says. It also views and compares previous and current studies.
As a new option for CADstream, Confirma introduced z3D contrast acuity, which enhances the visualization of time-intensity changes. The tool is under clinical investigation.
EDDA Technology showcased version 1.0 of its IQQA-Chest software that is tailored for softcopy review of digital radiographic chest images, as well as demonstrated works in progress software for dynamic liver imaging.
IQQA-Chest now features advanced DICOM connectivity (including DICOM storage, query/retrieval, structured report and send) and a refined worklist to enhance workflow efficiency. It detects lesions as small as 5mm.
IQQA-Liver, which is pending FDA approval, is designed to assist in the review of serial multi-phase CT acquisitions of the liver using dynamic imaging techniques. Clinical testing of the system has been conducted in two hospitals in China.
iMED introduced its CAD Colon 1.0 which identified 85 percent of polyps of 5mm to 10mm and 95 percent of polyps above 10mm in an internal clinical study on 52 symptomatic patients. It is now being tested within IMPACT, a multicenter clinical study which targets to analyze more than 350 patients.
Invivo Corp. showcased DynaCAD version 1.1 breast MRI CAD system with additional features for improved workflow and increased diagnostic confidence. Enhancements include standardized structured reporting, improved image viewing and image analysis and new options for interventional planning. It also has expanded and configurable archiving options for automatic creation of post-processing image series and storage to PACS archives and export options available in multiple file formats for incorporating DynaCAD data into other PC applications and to create CDs and DVDs.
Kodak's Health Group announced enhancements to its film-based mammography CAD system that include a viewing application for CAD results in portrait or landscape mode and the ability to save scanned mammograms as DICOM files. As films are digitized for CAD, they also can be sent to an archive or any vendor's PACS. Also new is a feature that allows users to save log files from the system and report the number of markers per film and per case. Kodak also showed a works-in-progress that will enable its mammography CAD hardware to also run bone mineral density tests.
Median Technologies showcased its web-based software CAD-Lung and CAD-Colon. The works-in-progress software provides tools and accurate
