The statistics are clear. Lung cancer is the No. 1 cancer killer, taking more lives annually than breast, prostate, and colorectal cancer combined. According to the American Cancer Society, only 15 percent of lung cancers are detected in the earliest and most treatable stage. Colorectal cancer is the second leading cause of cancer deaths. Breast cancer is the second leading cause of cancer deaths in women today - and the most common cancer among women. According to the World Health Organization, more than 1.2 million people will be diagnosed with breast cancer this year worldwide. The ACS estimates that in 2005, approximately 211,240 women in the United States will be diagnosed with invasive breast cancer.
As more emphasis is 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 this year's Radiological Society of North America meeting, 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 colongraphy and lung CT.
However, vendors made it clear that CAD is far from replacing the physician, but instead helping to improve the radiologic interpertation process. Enhancements to systems 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 desisions with treatment planning.
If you didn't make it all the way around the floor or not on the show floor at all, here are some details of what CAD vendors had on display. Vendors are listed in alphabetical order.
3TP Imaging Sciences announced at RSNA it changed its name to CAD Sciences. The change more accurately reflects its current expanding base of products in computer aided diagnosis (CAD) for breast and prostate MRI, the company says.
CAD Sciences' CAD products use a proprietary Full-Time-Point analysis algorithm (fTP) that offers users an advanced processing algorithm in conjunction with robust reporting and streamlined workflow capability.
Cedara, a Merge Healthcare company, announced the market release of B-CAD 1.0 that is designed to assist radiologists in the analysis of breast lesions using ultrasound images.
Cedara B-CAD provides tools for automatic image analysis, segmentation and classification for breast ultrasound. It assists radiologists in the analysis of solid breast nodules by automatically analyzing, segmenting and classifying shape and orientation characteristics of user-selected regions of interest. Addressing the need for consistent reporting practices, B-CAD automatically generates a report using the ACR BI-RADS ultrasound lexicon classification form, Cedara says.
Cedara has inked an agreement with Eastman Kodak Company that allows Kodak's Health Group to distribute Cedara B-CAD to its customers as part of an integrated system with the Kodak Carestream mammography workstation. Kodak's workstation is designed for viewing and storing mammography images and data from full-field digital mammography (FFDM) modalities from multiple viewers. The FDA-cleared workstation also can display images and data from a full range of modalities including ultrasound, MR, CR, DR, nuclear medicine, PET and digitized images.
Confirma at RSNA highlighted new features, products and options to CADstream, its flagship CAD software designed for breast MRI studies.
Confirma announced that an expanded version of SureLoc, CADstream's interventional guidance tool, is now compatible with all interventional guidance methods and equipment. SureLoc reports needle target for both grid and pillar methods in real-time, displays images and needle position in a patient's orientation and can be made available on any networked PC for access in the MR suite.
CADalog is another new feature of CADstream. The tool provides storage and timely access to CADstream studies saved with a CADalyst user interface, as well as studies available for on-demand retreival, Confirma says. In addition, CADalog is able to view and compare previous and current studies.
As a new option with CADstream, Confirma introduced z3D contrast acuity, which enhances the visualization of time-intensity
