Prototype FFR-CT software shows high accuracy vs. invasive FFR October 2, 2014 -- A software-based technique aimed at deriving CT-based blood flow data without invasive procedures showed similar accuracy to invasive fractional flow reserve (FFR) for determining the significance of coronary stenosis, according to a new report in the American Journal of Cardiology.
ASTRO: Imaging, radiation oncology increasingly work as one September 16, 2014 -- SAN FRANCISCO - Imaging is central to the unprecedented wave of medical specialties converging on cancer care. But it will take more than what today's radiologists are trained for to better understand cancer's mysteries, according to a keynote address by Dr. Hedvig Hricak, PhD, on Monday at the American Society for Radiation Oncology (ASTRO) meeting.
Mich. researchers hope to revamp lung CT image processing September 12, 2014 -- A new study at the University of Michigan aims to speed up image processing for low-dose CT lung cancer scans in the hopes of reducing reconstruction times to just a few minutes, which should result in lower radiation doses to patients.
Start-up advances MR-guided procedures with software platform September 4, 2014 -- Wisconsin researchers are developing a new software platform that would allow surgeons to observe the brain in real-time on MRI during surgical and therapeutic drug interventions. The goal of their company, called InseRT MRI, is to develop customized MRI-guided minimally invasive procedures.
Segmentation technique supports coronary CAD August 26, 2014 -- A new coronary artery segmentation and tracking method is showing promise for supporting computer-aided detection (CAD) schemes that can read coronary CT angiography scans to look for arteries blocked by both soft and calcified plaque, according to research published in Medical Physics.
MRI-guided catheter could upgrade stroke treatment August 22, 2014 -- A new steerable MRI-guided catheter can navigate through blood vessels from the groin to the brain in a search for clots to destroy, according to research from the University of California, San Francisco.
Decade of lung CAD brings insight, but little daily use August 19, 2014 -- Computer-aided detection (CAD) is known to boost radiologist performance in the detection of lung nodules, and radiologists certainly need the help. But despite a decade of fine-tuning and some powerful new capabilities, CAD systems haven't found a place in daily practice at most imaging facilities
MRI histogram analysis predicts bladder tumor aggressiveness August 15, 2014 -- Sophisticated histogram-based measurements of diffusion on MRI scans can predict bladder tumor aggressiveness noninvasively, according to a new study in Abdominal Imaging. The results could potentially help clinicians tailor therapy to individual patients, and even help predict which patients' tumors will metastasize.
Automated CT tool reveals pulmonary hypertension August 8, 2014 -- In a new study that used computer-aided analysis, the presence of low normal lung tissue volume correlated with pulmonary arterial hypertension at 3D CT. The technique could offer a more accessible and less invasive diagnostic test than right heart catheterization, according to researchers from Japan.
Standard mammography image processing best for calcifications July 31, 2014 -- Standard image processing algorithms help mammography detect calcification clusters more effectively than low-contrast or film-screen algorithms and could reduce false positives, according to a new study published in the August issue of the American Journal of Roentgenology.
