Rapid 3D MRI

Clinical knee MRI examinations typically utilize 2D imaging methods with thick slices, requiring upwards of 20-25 minutes of scan time, and yet not producing any quantitative information. New rapid 3D MRI methods can great reduce scan time while at the same time providing additional diagnostic information and detecting early disease features.

Our work aims to improve the value of MRI in diagnostic joint imaging through new MRI methods to reduce scan time and improve resolution and visualization of fine structures. We are also working to incorporate new methods to evaluate synovitis and tissue microstructure which cannot be assessed with conventional MRI. Lastly, we hope to do this in both knees simultaneously, without added scan time.
