Automated algorithms help spot change in serial CT exams
July 7, 2014 -- Most PACS vendors don't include automatic deformable image registration algorithms in their workstation software. But they should, as these can sharply reduce the time it takes for radiologists to match lung nodule locations on serial lung CT scans, according to researchers from Stony Brook Medicine.
New volume-based criteria from NIH predict cancer survival
June 25, 2014 -- Tumor assessment criteria that account for both tumor density and volume more accurately reflect tumor burden, and they may improve treatment monitoring by predicting outcomes earlier than methods that rely only on tumor density, according to research from the U.S. National Institutes of Health (NIH).
ISCT's Rubin issues challenge to image processing firms
June 20, 2014 -- Advances in image processing have given radiologists new tools to find the abnormalities they're looking for. But Dr. Geoffrey Rubin believes that radiologists need better tools -- and quickly -- before they drown in a flood of data being produced by the new generation of CT scanners.
Patients can be identified based on 3D reconstructions
June 3, 2014 -- 3D surface reconstructions can produce beautiful renderings of a patient's face. So beautiful that individuals could potentially, although not easily, be identified just from their reconstructed CT scan, according to a study published in the June issue of the American Journal of Roentgenology.
3D tumor quantification yields prognostic value in liver cancer
May 12, 2014 -- Researchers from Johns Hopkins Hospital have developed 3D quantification software that can accurately quantify the extent of liver tumor necrosis from MRI after initial chemoembolization. It can also predict patient survival by identifying responders and nonresponders to treatment.
Algorithm spots changes in follow-up brain MRI studies
May 7, 2014 -- Detecting changes in follow-up imaging studies can be difficult due to technical factors as well as human error. A software algorithm developed by a Canadian research team may be able to provide radiologists with some assistance.
Efficiency, personalized medicine will drive CAD forward
April 24, 2014 -- Clinical adoption of computer-aided detection (CAD) software has plateaued and has largely been confined to mammography. To change that, next-generation CAD software will need to deliver efficiency gains, interactivity, and algorithms that are personalized for patients, according to Dr. Eliot Siegel of the University of Maryland.
CAD detects retained surgical items on radiographs
April 21, 2014 -- Retained surgical items after surgery can be a significant source of mortality, morbidity, and cost. Computer-aided detection (CAD) technology can help prevent these costly errors, however, according to a group from the University of Michigan Health System.
SIR: Video glasses calm patients during treatment
March 24, 2014 -- Patients who wore video glasses showing pleasant movies or TV shows during interventional radiology procedures were less anxious than those who underwent procedures without glasses, concludes a new study presented at the Society of Interventional Radiology (SIR) annual meeting in San Diego.
Mammography texture analysis may predict false positives
March 24, 2014 -- False-positive results are an unfortunate aspect of mammography. But an algorithm that analyzes the texture of breast tissue on mammograms may be able to predict which patients are more likely to have negative biopsy results, paving the way for more individualized screening, according to researchers from the University of Pennsylvania.
Use of mobile devices in radiology requires extra care
March 9, 2014 -- VIENNA - Mobile devices such as tablets and smartphones are increasingly being employed in radiology applications, but users must take heed of crucial technical factors that can affect their performance for viewing images, according to a Saturday presentation at ECR 2014.
Radiology residents love their iPads -- most of the time
February 20, 2014 -- Is the iPad making a big difference in the lives of radiology residents who have them? For education, definitely. For clinical use, not quite yet, though the situation is evolving rapidly, according to a survey in the Journal of the American College of Radiology.
Research sheds light on why MRI CAD misses cancers
February 3, 2014 -- Despite its ability to improve the detection of breast cancer, breast MRI computer-aided detection (CAD) software still misses some. Several factors can affect the detection capabilities of the software, Korean researchers have found.
CAD uses MRI to differentiate brain tumors on FDG-PET
January 29, 2014 -- A computer-aided detection (CAD) algorithm that makes use of anatomic data from MRI scans can help radiologists differentiate between benign and malignant brain tumors on FDG-PET images, according to researchers from Yamaguchi University in Japan.
Software adds diagnostic value for heart disease patients
January 21, 2014 -- Dutch researchers have developed 3D visualization software that fuses anatomical and functional data into a single image. They believe the fused images make it easier to diagnose cases of coronary artery disease, according to a paper in the January issue of the Journal of Nuclear Medicine.
MRI volumetry forecasts IQ decline in sickle cell disease
January 17, 2014 -- Structural MRI volumetric analysis of gray matter in the brain can predict a subsequent decline in IQ in children with sickle cell disease, according to a team from the University of Maryland School of Medicine.
iPhone facilitates second opinions for on-call radiologists
January 13, 2014 -- On-call radiology residents can reliably use a smartphone to get after-hours advice from more experienced or specialized radiologists on challenging CT cases for the diagnosis of appendicitis, Korean researchers recently reported.
CAD may catch missed pulmonary embolism on CTPA studies
January 8, 2014 -- Pulmonary embolism can be missed on CT pulmonary angiography (CTPA) exams for many reasons, but computer-aided detection (CAD) software may be able to help prevent these damaging false negatives, according to research in the January issue of the American Journal of Roentgenology.
Quantitative 3D image analysis enables DCIS staging
December 16, 2013 -- Quantitative 3D breast image analysis of ductal carcinoma in situ (DCIS) on dynamic contrast-enhanced MRI can potentially shed light on the prognosis of these often mysterious lesions, according to research presented at RSNA 2013.
Facial transplants: Low-dose methods prove vital to success
December 5, 2013 -- CHICAGO - The complexity and extent of follow-up imaging often required in cases of facial transplantation means the application of all available low-dose imaging techniques must be pursued, according to top award-winning research presented at RSNA 2013.
