CAD for breast CT is improved with spiculation detection January 15, 2015 -- University of Chicago researchers significantly improved the performance of their computer-aided detection (CAD) algorithm for breast CT studies by having it detect lesion spiculation automatically, according to a new study.
New display calibration method may boost color image viewing January 8, 2015 -- Although color now pervades medical imaging, currently accepted calibration methods for imaging displays still rely on assessing gray levels. Display calibration may soon enter the color era, however, if a proposed extension to the DICOM Grayscale Standard Display Function is adopted.
CAD for virtual monochromatic CTC images shows high accuracy January 6, 2015 -- A computer-aided detection (CAD) algorithm analyzed virtual monochromatic dual-energy CT colonography (CTC) images accurately with few false positives in a study from Massachusetts General Hospital. The researchers believe the study could pave the way to more accurate minimal-prep CTC.
CAD detects lymph nodes at chest CT December 24, 2014 -- A new automated tool developed at the National Institutes of Health can detect mediastinal and abdominal enlarged lymph nodes more accurately than previous techniques, according to a presentation at the 2014 RSNA meeting.
Philips targets image-guided therapy with 1.2B bid for Volcano December 17, 2014 -- Continuing an aggressive expansion of its image-guided therapy and interventional radiology business, Philips Healthcare has inked a deal to pay $1.2 billion to acquire Volcano, a developer of intravascular ultrasound and fractional flow reserve technology.
Texture analysis sorts out indecipherable kidney lesions December 3, 2014 -- CHICAGO - Researchers from Johns Hopkins University have found a way to differentiate benign from malignant kidney lesions with great accuracy, solving a problem that has defied solutions since the advent of CT.
GE revives Signa MRI brand, launches CT and DBT December 2, 2014 -- CHICAGO - The return of its storied Signa brand in MRI, a new family of Revolution CT scanners, and a new digital breast tomosynthesis (DBT) system with market clearance are among the new product introductions at RSNA 2014 for multimodality vendor GE Healthcare.
CT with 3D printing helps visualize face transplantation December 2, 2014 -- CHICAGO - CT images are helpful for planning a complicated surgery, but physicians say that being able to hold a patient's skull in their hands makes surgical planning for face transplantation much easier. And this can be accomplished with 3D printing technology, researchers explained at the RSNA 2014 meeting.
Start-up RadLogics to offer cloud-based image analysis November 30, 2014 -- A new Silicon Valley start-up called RadLogics is combining big data image analysis with cloud-based technology to offer radiologists a tool to support the image interpretation process. RadLogics is demonstrating its technology to RSNA 2014 attendees in preparation for a product launch in early 2015.
3D printing from MRI untangles congenital heart surgery November 21, 2014 -- Taking cardiac MR images and turning them into 3D prints of the entire heart has gone from experiment to clinical use in Peoria, IL. It is helping doctors there plan complex congenital heart surgeries in young children, according to a presentation at the American Heart Association annual meeting in Chicago.
