Computer-assisted detection software has moved beyond its initial applications in mammography imaging and is becoming an essential tool in the diagnosis and management of various types of cancer. At RSNA, vendors are showing systems for film and digital mammography, but the real news extends into other applications. There are new systems for chest and abdominal CT images that not only facilitate lesion detection, but also support workflow by automatically generating measurements of lung and liver lesions. RSNA-goers also can check out a prostate MRI CAD application. Similar to breast MRI CAD, the system helps users efficiently sort through the volume of MRI data to more efficiently diagnose prostate disease.

Carestream Health (Booth 2513) is debuting CAD for chest and digital mammography.

In addition to CAD for film-based mammography, Carestream is showing CAD software for its CR-based mammography platforms and CAD for other vendors’ full-field digital mammography (FFDM) systems. The CAD for CR and FFDM solutions are available outside of the United States. The company also is demonstrating chest CAD and bone mineral density testing on its Kodak Directview DR 3000 platform, which are only available in China.

Confirma (Booth 7950) is unveiling the next generation of CADstream for breast MRI enhancements, CADstream for prostate MRI and the Access Breast Coil.

CADstream for breast MRI includes a new customizable BI-RADS-centric user interface that accommodates a variety of user experience levels. Additional CADstream enhancements include improved 3D renderings and volume summaries and morphology reporting tools.

CADstream Prostate is designed to improve quality, standardization and efficiency in MRI studies of the prostate. Confirma’s application-specific product provides image registration, image alignment between contrast series and T2 images and uptake and washout maps. The system also features multiplanar reformatting with subtractions, MIPs and prostate-specific lesion reporting.

Confirma’s Access Breast Coil’s open design provides flexibility when performing interventional procedures, with both lateral and medial access.

Based on an open-system architecture, SecondLook Digital is optimized for digital mammography systems. In addition, iCAD’s SecondLook Digital provides a flexible DICOM connectivity solution enabling universal compatibility with PACS and review workstations.

Median Technologies (Booth 8548) is showcasing its complete portfolio of Lesion Management Solutions, including LMS-Lung/Track and LMS-Liver CAD systems.

LMS-Lung/Track and LMS-Liver are designed to efficiently assist radiologists managing oncology patients in all steps. They segment user-identified lesions and measure key characteristics such as volume and longest axial diameters. They also pair lesions in follow-up exams, compute growth and doubling time and generate reports. LMS-Lung/Track and LMS-Liver perform tasks automatically to improve workflow and reduce intra- and inter-observer variability. LMS-Lung/Track and LMS-Liver support images acquired on any multidetector CT scanner and can be integrated with modality or PACS/RIS workstations.

Medipattern Corporation (Booth 5515) is announcing new B-CAD products: multiple versions of B-CAD for breast ultrasound imaging and one version for breast MRI.

B-CAD 1.2.1 for breast ultrasound imaging is available in a wide range of formats. The solution includes a DICOM-network-ready PC with a B-CAD viewer and CAD reporting system, ideal for facilities just entering a PACS environment. Two software plug-in modules for PACS partners Cedara and Sectra can plug into new or existing PACS viewers. B-CAD 1.2.1 delivers ease of workflow, enabling radiologist-customizable methods that easily integrate into the natural reading process.

Medipattern is showing its morphology CAD for breast MRI as part of Confirma’s Version 5 CADstream product. It performs detection and characterization of features based on physical shapes or morphology within a breast MRI.

Medipattern also is showing a work in progress for CAD on whole-breast ultrasound. Next-generation B-CAD reads the images in cine loops, automatically detecting and characterizing lesions. CAD results are reviewed by the radiologist for editing and then B-CAD automatically enters all of the evidence and findings into a natural language report.

Riverain Medical (Booth 8503) is highlighting its OnGuard Chest X-ray CAD system.

OnGuard works in conjunction with the reading of original standard AP/PA digital chest x-rays. It provides practical early detection by quickly identifying solitary pulmonary nodules between 9mm and 30mm in diameter that may be early stage lung cancer. The OnGuard system supports efforts to proactively detect lung cancer when it is most treatable. It also integrates with any PACS workstation to provide a solution to finding subtle suspicious nodules that may warrant further examination.
