3D-bioprinted model reproduces heart structure, function
August 1, 2019 -- Researchers from Pennsylvania have developed a way to create realistic 3D-bioprinted heart models that reproduce not only the cardiac texture and microstructure of MR images but also cardiac function and cell growth. Their new 3D bioprinting technique is the subject of an article published in the August 2 issue of Science.  Discuss

Cinematic rendering complements CT in diagnosing colitis
July 30, 2019 -- Radiologists who had access to cinematically rendered images of the colon in addition to conventional CT scans -- as opposed to CT alone -- reported clear improvements in their capacity to diagnose ulcerative colitis in a new study, published in the August issue of the Japanese Journal of Radiology.  Discuss
How can 3D printing improve kidney cancer surgery?
July 26, 2019 -- 3D-printed models based on CT scans not only facilitated presurgical planning for kidney cancer removal but also enhanced navigation during surgery, ultimately reducing patient blood loss in a new study, published online July 21 in the Journal of International Medical Research.  Discuss
3D printing enhances chest wall reconstruction
July 24, 2019 -- Where standard methods to reconstruct damaged chest walls fall short, 3D printing may offer a hopeful alternative, according to researchers from the Mayo Clinic. They demonstrate several benefits of using a 3D-printed model to plan chest wall surgery in an article published in the August issue of Trauma Case Reports.  Discuss
