4D MRI Research
The multidisciplinary MR/CT program is researching ways to reduce MR imaging exam time and minimize anesthesia or sedation used during imaging exams. In the multi-year NIH/NHLBI funded study, Functional Cardiovascular 4D MRI in Congenital Heart Disease, Lurie Children's cardiologists and radiologists are collaborating with Northwestern bioengineers to develop a comprehensive 20-minute 4D MR exam that might replace the standard 60-90 minute MRI protocol. In addition to studying how the new technique may reduce exposure to anesthesia, the team is investigating how 4D visualization of complex blood flow dynamics may predict progression of cardiovascular disease. The visualization is shown below.
