Black-blood CT sheds light on intraluminal heart anatomy
October 9, 2019 -- An advanced imaging technique called black-blood CT can leverage cinematic rendering technology to provide a detailed view inside the lumen of vasculature and potentially bolster cardiac evaluation, according to an article published online October 1 in the Journal of Cardiovascular Computed Tomography.  Discuss
New technique unravels 3D MRI scans of placenta
October 3, 2019 -- When applied to 3D MRI, a new mapping algorithm can generate virtual placenta models that open up and flatten -- enhancing the visibility of the placenta during pregnancy, according to an upcoming presentation at the International Conference on Medical Image Computing and Computer Assisted Intervention in China.  Discuss
Cinematic rendering offers clinical utility in MSK CT
September 26, 2019 -- What is the clinical utility of cinematic rendering in musculoskeletal (MSK) CT? It enhances the visualization of soft-tissue injuries and fractures -- in turn improving trauma evaluation and preoperative planning, Dr. Savvas Nicolaou said in a presentation at the recent International Society for Computed Tomography meeting in San Diego.  Discuss
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
