3D VR models improve kidney-sparing surgery outcomes
September 18, 2019 -- Examining 3D virtual reality (VR) models during presurgical planning for robotic-assisted partial nephrectomy led to reductions in operating time, blood loss, and hospital length of stay compared with planning based on MRI and CT scans alone in a new study, published online September 18 in JAMA Network Open.  Discuss
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.
Virtual reality relieves kids' anxiety over chest x-ray
September 9, 2019 -- Educating pediatric patients about their upcoming chest x-ray exam with virtual reality technology helped reduce preprocedural anxiety, and, in turn, the need for repeat exams and parental presence in the imaging suite in a new study, published online September 9 in JAMA Pediatrics.  Discuss
3D printing cuts surgery time for eye socket repair
September 4, 2019 -- Examining 3D-printed models based on head CT scans enabled clinicians to customize implants required for eye socket fracture repair and reduce the time to complete the surgery by roughly 50% in a new study, recently published online in Academic Radiology.  Discuss
3D MRI enables contrast-free evaluation of cardiac strain
August 29, 2019 -- Researchers from the U.K. have developed a new 3D MRI technique for calculating heart muscle strain. They discuss how their method may help improve the accuracy of quantifying cardiac health without the need for gadolinium contrast in an article published online August 28 in Scientific Reports.
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
