New 3D bioprinting method produces functional organ tissue

September 16, 2019 -- Researchers from Harvard University have developed a new 3D bioprinting method that uses a combination of stem cells and 3D CT data to produce functional, patient-specific organ tissue. The resulting 3D-bioprinted models are poised to facilitate organ repair and restoration, according to an article recently published online in Science Advances.

AI detects pulmonary nodules on chest x-rays

September 16, 2019 -- A computer-aided detection software application based on artificial intelligence (AI) is able to identify pulmonary nodules quickly and accurately on chest x-rays, offering potential to serve as a triage or second-reading tool for radiologists, according to research published online September 11 in Clinical Radiology.
