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.July 23, 2019UltrasoundAR, ultrasound boost efficiency of needle injectionsAugmented reality (AR) may improve the performance of ultrasound image guidance, say researchers from Canada who developed a new technique using AR and ultrasound to help pilot needle insertion into the spine. They discuss their method in an article recently published in Ultrasound in Medicine and Biology.July 21, 2019CTCT CAC linked to cardiovascular mortality in young adultsPositive scores on CT coronary artery calcium (CAC) scans were strongly associated with an increased risk of heart disease and all-cause mortality in young adults in a new study, published online July 19 in JAMA Network Open. CT CAC testing could help direct these individuals to preventive therapy, researchers say.July 21, 2019CTCould a metabolic test revamp CT lung cancer screening?A low-cost metabolic test that uses MR spectroscopy to analyze blood and tissue samples may complement the early detection of lung cancer and help clinicians identify individuals who would benefit most from CT lung screening, according to an article published online July 16 in Scientific Reports.July 17, 2019Advanced Visualization3D printing cuts hip fracture repair time, blood lossIntegrating 3D printing technology into presurgical planning for hip joint fracture repair can significantly reduce operating times and blood loss, compared with conventional methods, according to an article published online July 9 in Orthopaedics and Traumatology: Surgery and Research.July 17, 2019CTDemographic factors limit access to CT lung screeningSmokers who are older, uninsured, undereducated, and live in a rural area are more likely to be located farther away from a CT lung cancer screening facility and thus have limited access to screening services, according to an article published online July 11 in the Journal of the American College of Radiology.July 14, 2019Advanced VisualizationAR offers 3D image guidance for interventional proceduresResearchers from New York have developed a new image-guidance technique that uses augmented reality (AR) to facilitate interventional procedures. They detail how their method may help improve the ease and accuracy of catheter placement into the heart in an article recently published online by PLOS One.July 11, 2019CTCT perfusion shows promising utility in cancer treatmentThe CT perfusion scans of patients with pancreatic cancer revealed that those who responded well to chemoradiation therapy had higher blood flow measurements both before and after treatment than did patients who responded poorly in a new study, published online July 9 in Radiology.July 10, 2019Previous PagePage 20 of 63Next PageTop StoriesMolecular ImagingBrain PET tracer delivered intranasally for first time in humansThe study confirms the safety and efficacy of Ga-68 NOTA-insulin as a PET radiotracer that can be used for human neuroimaging.BreastRace, economics contribute to advanced-stage breast cancer diagnosesBreastMissouri's expanded mammography coverage law boosted screening by 45%CTCT colonography screening program sets benchmarksSponsor ContentWhen time is of the essence
![Images depict axial MRI scans in a 50-year-old premenopausal female patient with biopsy-proven 12-mm invasive lobular cancer in the lower outer quadrant of the left breast. Upper images are subtracted dynamic contrast-enhanced (DCE) MRI scans from the first and second postcontrast acquisitions. Lower images are ultrafast MRI scans obtained within 24 hours after the DCE study (four consecutive subtracted dynamic frames from time points [T] 6–9). There is marked background parenchymal enhancement (BPE) on the DCE MRI scans. Thus, the known cancer (arrow) is barely visible; it exhibits only slightly stronger enhancement than the normal fibroglandular tissue, which results in low conspicuity. At ultrafast MRI there is less BPE, and still the cancer is barely visible because it starts to enhance simultaneously with the BPE. The conspicuity of the cancer is even reduced compared with the DCE series. Both of the readers missed this cancer on both the DCE and ultrafast MRI scans.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2025/05/2025-05-06-rsna-ultrafast-dce-mri-breast.Gzvq76udFr.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
