Rapid 3D Articular Cartilage Imaging with Reduction of Truncation Artifacts

Three-dimensional knee imaging is useful for cartilage imaging but scan times can be prohibitively long. This study demonstrates a technique that can shorten scan time by about 40% by partially filling k-space using a linear prediction model, thus reducing truncation artifacts. Two radiologists reviewed images produced by this technique and determined them to be as acceptable as the gold standard images.
