New Zealand start-up scans 1st humans with spectral CT
July 18, 2018 -- Researchers from a start-up company in New Zealand have scanned the first humans with a spectral CT scanner based on solid-state digital detectors. The technology produces color images at much higher levels of resolution than traditional CT scanners and, thus, may improve diagnosis.  Discuss

Virtual reality adds depth to brain aneurysm diagnosis
June 20, 2018 -- Radiologists detected brain aneurysms just as accurately by examining CT scans with a virtual reality device as they did by reviewing conventional CT angiography and 3D rotational angiography scans, researchers reported in the July issue of Clinical Neurology and Neurosurgery.  Discuss
New 3D CT technique tops x-ray for diagnosing arthritis
June 19, 2018 -- Researchers from the U.K. have developed an algorithm capable of detecting subtle changes in the spacing between arthritic joints on 3D-reconstructed CT scans better than even standard x-ray imaging can, according to an article published online on June 18 in Scientific Reports.  Discuss

'Bitmap' technique enhances quality, speed of 3D printing
June 4, 2018 -- A new 3D printing technique can produce multimaterial 3D-printed models more rapidly and with a higher resolution than traditional techniques by converting MRI and CT scans into a series of black and white pixels, according to a study published online May 29 in 3D Printing and Additive Manufacturing.  Discuss
AI may help overcome barriers to medical 3D printing
May 21, 2018 -- How can artificial intelligence (AI) help ameliorate the high cost and long turnaround time of producing 3D-printed models? One possibility is by automating steps in the 3D printing process, according to a review article published online May 9 in Expert Review of Medical Devices.  Discuss
