Virtual reality enhances interventional rad training
August 6, 2015 -- By offering interventional radiology trainees what they need most -- practice -- virtual reality training may be poised to stand in for the conventional version, according to a recent talk by researchers who have developed an immersive virtual reality training environment.
Standards are emerging for use of color in medical imaging
July 31, 2015 -- For decades, the world of medical imaging has been visualized in shades of gray. But as color is becoming more common, challenges are emerging that mirror those solved years ago in grayscale imaging, namely regarding the use of standards to define the consistency of color images shown on different medical displays. Fortunately, help is on the way.
Software aims for realism in echocardiography
July 27, 2015 -- A new echocardiography software package released this month analyzes cardiac structure and function pixel by pixel to render detailed functional 3D images that could speed up diagnosis and reduce the number of exams needed in patients undergoing cardiac workups.
4D parathyroid CT sorts out lesion types
July 24, 2015 -- CT scans with 4D image reconstruction can separate parathyroid adenomas and hyperplastic lesions into three distinct lesion types based on enhancement patterns, alerting surgeons to the variations they will find, according to a study in Radiology. The findings also indicate that a three-phase scanning protocol is still needed, the authors believe.
MGH saves money and time printing 3D hearts
July 17, 2015 -- Researchers at Massachusetts General Hospital (MGH) in Boston say that having a 3D rapid prototyping printer in the cardiac imaging department is a potential boon for procedure planning and patient education -- and it doesn't break the bank.
Group creates 3D printed heart with CT, echo data
June 29, 2015 -- In what they are calling a major advance, researchers from Michigan have created a 3D model of a human heart using data from two separate cardiac imaging techniques: CT and echocardiography. They believe that such hybrid 3D models will be more accurate than those created from just one imaging modality.
CT lung CAD may require adjustment from radiologists
June 26, 2015 -- Computer-aided detection (CAD) for CT lung exams will be essential in the coming era of population-based lung cancer screening. But radiologists may have to change their way of reading studies to reap its benefits, according to a recent talk by Dr. Geoffrey Rubin from Duke University.
OCT tool offers fast intraoperative brain tumor imaging
June 19, 2015 -- A new brain tumor imaging technique based on optical coherence tomography (OTC) may offers surgeons a highly accurate way to visualize -- and ultimately resect -- malignant tumors during surgery, according to a report from Johns Hopkins University.
New CAD app generates radiology reports
June 5, 2015 -- Researchers from Oregon have developed a novel computer-aided detection (CAD) application for radiology reports -- one that churns out differential diagnoses, accurately drawing correlations between imaging findings and potential disease states, according to a presentation at the Society for Imaging Informatics in Medicine meeting.
New high-res 3D MRI map aids surgeons
June 4, 2015 -- Researchers at Duke University have created an ultrahigh-resolution 3D MRI map of the human brainstem, intended to help surgeons use deep brain stimulation to treat patients.
