3D luminescence imaging shows subtle bone damage September 13, 2016 -- Researchers at Trinity College in Dublin have devised an experimental 3D bone scanning technique that may improve the diagnosis of bone injuries without the use of ionizing radiation, according to a new study published in Chemical Communications.
3D reconstructions of shipwreck skulls posted online September 7, 2016 -- Researchers from Swansea University in the U.K have posted an online exhibition of 3D reconstructions of skulls and other artifacts from the 1545 wreck of Henry VIII's warship, the Mary Rose.
Texture classification eases lung CT analysis September 5, 2016 -- Dutch researchers have developed a semiautomatic method for classifying abnormal lung textures that reduces the time taken to analyze thoracic CT scans. They found the interactive labeling protocol is more efficient to use than a fully automated alternative.
A clinical take on whole-body dynamic PET August 26, 2016 -- A U.S.-Swiss research team has developed a promising method for whole-body dynamic PET. Their dynamic PET parametric imaging framework may be of value for commercial PET systems of limited axial field-of-view that are now established in the clinic.
4D flow MRI shows smallest hint of LV dysfunction August 23, 2016 -- Four-dimensional flow MRI can depict even subtle changes in left ventricular (LV) function, bringing new insight to the diagnosis of patients with mild left ventricular dysfunction and remodeling, concludes a study published on 17 August in PLOS One.
Navigation tool permits biopsies in closed MRI scanners August 22, 2016 -- A new investigational technique is enabling German researchers to perform MR-guided liver biopsies of lesions that can't be seen using other modalities and are inaccessible in most MRI scanners, according to a new study in the August edition of European Radiology.
How low can CT radiation dose go for lung screening? August 18, 2016 -- We're making progress in the race to reduce radiation dose for CT lung cancer screening to ever-lower levels. But as dose drops, image noise grows. Fortunately, researchers are refining image processing techniques that can improve image quality while driving CT dose down to the level of a chest x-ray.
New neural network outperforms CAD for mammography August 16, 2016 -- A convolutional neural network trained on a large dataset of mammographic lesions outperformed a conventional mammography computer-aided detection (CAD) scheme, according to a new Dutch study published this month. These networks can be fine-tuned based on radiologists' knowledge.
Siemens, InSightec to partner August 16, 2016 -- MR-guided focused ultrasound developer InSightec has signed an agreement with Siemens Healthineers to develop compatibility between Exablate Neuro and Siemens' 1.5- and 3-tesla MRI systems, Magnetom Aera and Skyra.
