As history looks back on RSNA shows, 2006 should stand as a watershed year for CAD. Breast imaging and lung solutions remain relevant and are certainly maturing. Breast MRI CAD continues to streamline breast MRI interpretation. But the real news in CAD is the broadening of applications. “In three years, it will be hard imagine an image coming through a hospital without some type of CAD applied,” predicts Dave Faller, general manager of Kodak’s CAD business.

PACS vendors are integrating digital mammography CAD into PACS workstations, and the first enterprise lung CAD solutions that bring CAD to the PACS workstation is on the market. The need for PACS integration is clear. “The average hospital performs 150 to 200 chest x-rays a day,” states Tim Ketchmark, vice president for EDDA technology. “Radiologists don’t want to break workflow to use the application.” Most PACS options allow the radiologist to determine which marks to save, which also aids workflow because the reader does not need to review previously dismissed marks.   

Visitors to the show floor checked out new and upcoming liver, colon and bone densitometry systems. And that’s just the beginning. CAD Sciences Chief Technology Officer James Conklin, MD, indicated that the company is working on a prostate solution and is evaluating other organ systems with researching at multiple institutions. The company is partnering with Saphenia to apply CAD technology to lung, liver and renal nodules. Breast MRI CAD provider Confirma also is evaluating a prostate solutions and expects to launch a system at RSNA 2007. State-of-the-art systems transcend mere markers, said Conklin, who noted that CAD Sciences’ solution can provide a quantifiable measurement of a tumor’s response to therapy weeks and months before a change in tumor size.   

Another company heavily invested in CAD is Kodak. The company expects to submit its FFDM CAD system for FDA approval early in 2007. Other Kodak CAD works-in-progress include an osteoporosis detection system that relies on an x-ray image of the hand. A future ICU CAD system from Kodak will enhance chest images to provide consistent renderings and allow physicians to more easily evaluate line placements.


CAD Sciences debuted Server 2.4 of its Full-Time-Point MR image post-processing engine and WorkSpace 2.1, a streamlined MR image viewer that facilitates the analysis of fTP colorized images and quantitative output data.

The products are the next generation of CAD Sciences’ advanced pharmacokinetic analysis software tools that assist the radiologist with lesion identification, characterization and diagnosis reporting. This advanced set of radiology software offers one-click lesion diagnosis reporting in conjunction with the ability to monitor vascular permeability over time in lesions treated with radiation, hormonal or chemotherapy. These capabilities have been integrated into an advanced workflow roadmap regime that guides the radiologist through the series of sequential tasks that must be performed in order to arrive at a diagnosis.     

Workspace 2.1 offers one-click lesion diagnosis reporting, permitting the radiologist user to identify lesions and generate diagnosis reports with graphical and quantitative analysis of tissue biology. These reports include numerical measurements of vascular permeability and cellular density, considered key physiological indicators of cancer, as well as standard contrast wash-in and wash-out measurements. Users may select a lesion for analysis by simply pointing and clicking on a region of interest. Statistical analysis of the lesion may be performed in 2D or 3D based on user preference. For many current users, automated lesion selection has eliminated manual selection and circling of ROIs (Regions of Interest) to streamline diagnosis reporting.

This latest product release contains a new Therapy Response Monitoring Module (TRM) module that assists radiologists wishing to monitor over time a patient’s response to cancer therapy. TRM is used by radiologists to compare, on a quantitative basis, changes in vascular permeability that are obtained at various stages in a patient’s cancer therapy treatment and measured by the Server 2.4’s advanced fTP algorithm.     

WorkSpace 2.1 has been configured to permit image viewing in dual, triple or super-wide monitor settings. In addition, users may now create multiple customized reporting templates for referring physicians according to
