Robert Bruce[email protected]BreastU-Systems develops CAD tools for breast ultrasoundMammography remains the primary screening modality for breast cancer. For women with dense breasts, however, ultrasound is increasingly used as an adjunctive diagnostic tool. U-Systems out of San Jose, CA hopes to apply computer-aided detection (CAD) technology to breast ultrasound.February 26, 2002PACS/VNADisaster recovery in radiology, Part III: JCAHO requires emergency preparednessThe Joint Commission on Accreditation of Healthcare Organizations (JCAHO) requires accredited U.S. facilities to develop emergency preparedness plans. Data must be protected against loss, destruction, tampering, and unauthorized access or use. For hospitals using the ASP model, will these rules do the job?January 30, 2002PACS/VNADisaster recovery in radiology, Part II: The New York City experienceMost New York City healthcare facilities were not damaged or compromised on September 11. The exception was NYU Downtown Hospital (Beekman), which was just four blocks from the World Trade Center site and suffered power and telephone interruptions because the nearby ConEd power station was destroyed.January 23, 2002PACS/VNADisaster recovery in radiology, Part I: Protecting your images and informationThe September 11 terror attacks in the U.S. have prompted hospitals and radiology departments to take a hard look at disaster recovery. Imaging facilities are assessing how well their operations might function in case of massive natural or man-made cataclysm, how fast they could get back in operation, and whether they could retrieve images and data.January 16, 2002Practice ManagementDisaster recovery case study #2: UCSF’s model for PACS recovery from off-site storageOne of the most highly developed disaster recovery systems is at the 600-bed University of California, San Francisco Medical Center, where the state requires special seismic testing before each heavy new scanner is installed.January 16, 2002Practice ManagementDisaster recovery case study #1: The Dallas VA alternativeThe 426-bed Dallas Veterans Affairs Medical Center has a well-developed disaster recovery plan. Its requirements are somewhat different from those of nongovernmental hospitals, as all VAMC physicians and other staff are U.S. employees, and must follow the medical center’s standards. There are no off-site referring physicians.January 16, 2002CTRSNA special session probes ethics of whole-body screeningA 90-minute special-focus session at the RSNA meeting focus on the potential benefits and harms of CT screening. The session will be led by Dr. William Black of Dartmouth-Hitchcock Medical Center in Lebanon, NH.November 22, 2001Nuclear MedicineBracco rations popular gall bladder agentsNuclear medicine physicians and technologists have been scrambling for replacements following Bracco Diagnostics' announcement that its imaging pharmaceuticals Kinevac and Choletec will no longer be available.October 21, 2001BreastHologic's new CEO takes aim at digital mammographyHologic CEO John Cumming will never be accused of being passive. Just two weeks after taking over as CEO, Cumming laid off 10% of Hologic's 350 employees and announced the Bedford, MA-based vendor's intent to achieve the top position in digital mammography.September 17, 2001Clinical NewsDuPont's Definity echoes through contrast marketDuPont Pharmaceuticals is preparing its U.S. launch of Definity, an ultrasound contrast agent that was cleared by the Food and Drug Administration in August.

![Images depict axial MRI scans in a 50-year-old premenopausal female patient with biopsy-proven 12-mm invasive lobular cancer in the lower outer quadrant of the left breast. Upper images are subtracted dynamic contrast-enhanced (DCE) MRI scans from the first and second postcontrast acquisitions. Lower images are ultrafast MRI scans obtained within 24 hours after the DCE study (four consecutive subtracted dynamic frames from time points [T] 6–9). There is marked background parenchymal enhancement (BPE) on the DCE MRI scans. Thus, the known cancer (arrow) is barely visible; it exhibits only slightly stronger enhancement than the normal fibroglandular tissue, which results in low conspicuity. At ultrafast MRI there is less BPE, and still the cancer is barely visible because it starts to enhance simultaneously with the BPE. The conspicuity of the cancer is even reduced compared with the DCE series. Both of the readers missed this cancer on both the DCE and ultrafast MRI scans.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2025/05/2025-05-06-rsna-ultrafast-dce-mri-breast.Gzvq76udFr.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
