LevelCheck algorithm targets wrong-site spinal surgery April 23, 2015 -- A new algorithm called LevelCheck -- designed to prevent wrong-site spinal surgery -- boasted near-perfect accuracy in a trial by Johns Hopkins University researchers. By matching preoperative CT scans to intraoperative radiographs, LevelCheck confirms for surgeons that they are targeting the correct vertebral level.
Coregistered 3D US plus angio boosts aneurysm surgery April 6, 2015 -- Combining rotational digital subtraction angiography with 3D ultrasound creates a powerful pair for guiding aneurysm surgery when images are dynamically coregistered during procedures, according to a new study by German researchers and published in PLOS One.
Imaging vendors have options for image processing hardware March 27, 2015 -- When developing new imaging systems, OEMs can choose from many types of computer hardware platforms. Platform selection in turn affects the type of image processing to be used, which then influences the radiologist's work when viewing medical images. Software architects from advanced visualization developer ContextVision offer some guidance.
FDA in hand, EchoPixel preps for launch of True 3D platform March 24, 2015 -- Advanced visualization developer EchoPixel is moving its True 3D Viewer technology to market after receiving clearance from the U.S. Food and Drug Administration for the platform, which creates holographic displays from CT and MRI data.
Apple announces ResearchKit app software for medical researchers March 10, 2015 -- Apple introduced ResearchKit, an open-source software framework designed to benefit medical researchers, at its March 2015 Special Event on Monday. Using ResearchKit, researchers will be able to more easily design apps that allow patients to remotely consent to join clinical trials and provide data.
Automated perfusion mapping falls short in stroke March 8, 2015 -- VIENNA - Automatically generated color CT perfusion maps have a role in the emergency care of ischemic stroke patients, but they are less accurate than manually generated maps, according to research presented at ECR 2015.
CTPA-based prediction model nails pulmonary hypertension March 7, 2015 -- VIENNA - When do suspected pulmonary embolism patients actually have pulmonary hypertension (PH)? Although the treatment approach for the conditions is quite different, their presentation can be similar. But a new CT pulmonary angiography (CTPA) tool can accurately predict PH in patients without pulmonary embolism, according to researchers from Israel.
CAD boosts breast MRI sensitivity March 6, 2015 -- VIENNA - Breast MRI already has high sensitivity, but can it be even higher? The answer is yes, if computer-aided detection (CAD) is thrown into the mix, according to a presentation at ECR 2015. In fact, the CAD system detected previously missed cancers nearly as well as it did screen-detected cancers.
CAD becomes a spell-check for small polyps March 6, 2015 -- Computer-aided detection (CAD) can only enhance performance if used correctly, and it does not reduce the need for training, according to a presentation on Friday at ECR 2015 in Vienna. CAD for colonography has shown promise, but radiologists need to understand sensitivity and specificity issues, as well as when CAD should be deployed.
Vertebral CAD aces detection of compression fractures February 26, 2015 -- A new computer-aided detection (CAD) scheme can robustly detect vertebral compression fractures on spine CT images. The algorithm was developed by a team led by Dr. Ronald Summers, PhD, from the U.S. National Institutes of Health.
