3D MRI helps predict osteoarthritis risk after ACL tears
August 26, 2019 -- Virtual 3D models of the knee based on MRI scans of anterior cruciate ligament (ACL) tears revealed which regions in the knee were most likely to develop osteoarthritis in a new study, published online in Clinical Biomechanics. The technique could help individualize rehabilitation strategies for patients following ACL surgery.  Discuss
3D models advance therapy for heart rhythm disorders
August 21, 2019 -- 3D heart models based on MRI scans allowed for the virtual simulation of existing and future irregular heartbeats in patients with atrial fibrillation in a new study, published online August 19 in Nature Biomedical Engineering. The models helped pinpoint distinct regions in the patients' heart that would benefit most from ablation therapy.  Discuss
4 applications of cinematic rendering in maxillofacial CT
August 20, 2019 -- Swiss researchers have used cinematic rendering to create photorealistic images of head CT and conebeam CT scans. They assess the potential benefits of integrating these images into the evaluation of maxillofacial anatomy and pathology in a study recently published online in Dentomaxillofacial Radiology.  Discuss
7T MRI and 3D printing uncover signs of severe MS
August 14, 2019 -- A combination of 7-tesla MRI and 3D printing technology has revealed that patients with a growing number of chronic active brain lesions are also more likely to have more debilitating forms of multiple sclerosis (MS), including individuals receiving standard treatment. The findings were published online August 12 in JAMA Neurology.  Discuss
3D-printed head customizes neurosurgery simulation
August 8, 2019 -- Researchers from Australia have created a 3D-printed head model, based on a combination of MRI and CT angiography scans, that allows for the realistic simulation of neurosurgical procedures. They discuss the specifics of their method in an article published online August 1 in 3D Printing in Medicine.  Discuss
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
Top 5 clinical applications of pediatric 3D printing
July 31, 2019 -- What are the most common clinical applications for 3D-printed models created from MRI scans of pediatric patients? A team from Ohio explored the various applications and the role radiologists play in production of the models in a new article, recently published online in the Journal of Magnetic Resonance Imaging.  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
