22-year-old man with acute knee injury. A and B, Sagittal clinical (A) and deep learning (DL)-accelerated (B) fat-suppressed proton density—weighted images show bone contusions (arrows) in lateral femoral condyle and lateral tibial plateaus, consistent with anterior cruciate ligament tear. It is difficult to distinguish between clinical and DL-accelerated images. Such indistinguishability is uncommon for traditional acceleration techniques at high acceleration factors, particularly for challenging case of 2D images with strong requirements for spatial resolution and anatomic fidelity.
