CAD/PACS integration may aid diagnostics
Two recent studies predict that computer-aided diagnosis schemes will likely be incorporated into PACS in the future.
Two recent studies predict that computer-aided diagnosis schemes will likely be incorporated into PACS in the future.
In one paper, Kunio Doi, Ph.D., director of Kurt Rossmann Laboratories for Radiologic Image Research at the University of Chicago, predicts that CAD schemes could be assembled as packages and implemented as a part of PACS. A package for chest CAD, for example, may include the computerized detection of lung nodules, interstitial opacities, cardiomegaly, vertebral fractures, and interval changes in chest radiographs, as well as computerized classification of benign and malignant nodules and differential diagnosis of interstitial lung diseases (Comput Med Imaging Graph 2007;31(4-5):198-211). Doi notes the potential to search PACS for differential diagnoses once researchers develop a reliable method to quantify the similarity of a pair of images.
The second paper reports a CAD/PACS integration toolkit designed to integrate CAD results with clinical PACS (Comput Med Imaging Graph 2007;31(4-5):195-197). One version uses the DICOM secondary capture object model to convert the screenshot of CAD results to a DICOM image file for PACS workstations to display. A second version converts CAD results to a DICOM structured report based on IHE workflow profiles, according to lead author Dr. Zheng Zhou of the Image Processing and Informatics Laboratory at the University of Southern California.
What a New Mammography Study Reveals About BMI, Race, Ethnicity and Advanced Breast Cancer Risk
December 8th 2023In a new study examining population attributable risk proportions (PARPs) based on data from over three million screening mammography exams, researchers found that postmenopausal Black women had the highest BMI-related PARP and premenopausal Asian and Pacific Islander women had the highest breast density-related PARP for advanced breast cancer.
Study: Contrast-Enhanced Mammography Changes Surgical Plan in 22.5 Percent of Breast Cancer Cases
December 7th 2023Contrast-enhanced mammography detected additional lesions in 43 percent of patients and led to additional biopsies in 18.2 percent of patients, over half of whom had malignant lesions, according to a study of over 500 women presented at the recent Radiological Society of North America (RSNA) conference.
