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.
iPad offers promise for mobile assessment of acute GI bleeding
March 6, 2014 -- VIENNA - An iPad can be an effective tool for reading CT angiography studies in patients suspected of having acute gastrointestinal (GI) bleeding, according to a presentation from Italian researchers on Thursday 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.
Siemens RSNA launches include Force CT scanner, angio unit
December 4, 2013 -- CHICAGO - Siemens Healthcare is launching a range of new products at this week's RSNA meeting, including the third generation of its dual-source CT architecture, a new angiography system, and a major ultrasound technology upgrade.
Germany's rising stars step into limelight at RSNA
December 4, 2013 -- CHICAGO - More than 30 of Germany's brightest researchers have grabbed the opportunity to display their talents to a global audience at RSNA 2013 in a lavish government-funded initiative.
CAD may help uncover extracolonic findings on CTC studies
December 1, 2013 -- CHICAGO - Computer-aided detection (CAD) technology shows potential for identifying hard-to-find renal calculi and lesions on CT colonography (CTC) exams, according to research presented on Sunday at RSNA 2013.
Dinosaur vertebra fossil rises up in 3D from CT data
November 21, 2013 -- Noninvasive imaging techniques have long proved valuable for digging up the stories of fossils without damaging them. In a new study published online in Radiology, German researchers have gone a step further, making a carbon copy of a dinosaur vertebra using CT data and 3D printing.
House subcommittee mulls new approach to mobile app regulation
November 20, 2013 -- The debate over how best to regulate mobile medical apps reached the halls of the U.S. Congress this week as representatives sparred over a proposed bill that could strip the U.S. Food and Drug Administration of its authority to regulate many types of app software.
Radiology can benefit from mobile computing in myriad ways
November 15, 2013 -- Mobile computing technologies have the potential to reshape the practice of radiology, touching on areas such as interactions with referring physicians and other radiologists, image acquisition and transmission, education, and even patient care, according to an article in the December issue of Academic Radiology.
Ambient light rapidly degrades image quality on mobile devices
October 18, 2013 -- Maybe there's a reason radiologists work in dark rooms. A new study has found that the ability to interpret images correctly with mobile displays begins to decline if the devices are used in ambient light conditions brighter than the average office.
Mobile image viewer helps clinicians access images faster
October 3, 2013 -- Clinicians can access medical images much faster using mobile image-viewing software on Apple iPads without sacrificing diagnostic confidence or ease of use, compared with the use of traditional desktop-based software, according to researchers from the Mayo Clinic in Scottsdale, AZ.
