ReconResNet: Regularised residual learning for MR image reconstruction of Undersampled Cartesian and Radial data.

MRI is an inherently slow process, which leads to long scan time for high-resolution imaging. The speed of acquisition can be increased by ignoring parts of the data (undersampling). Consequently, this leads to the degradation of image quality, such as loss of resolution or introduction of image artefacts.

Intraoperative Computed Tomography Versus 3D C-Arm Imaging for Navigated Spinal Instrumentation.

Study Design: A prospective case-series study and a retrospective analysis of historical patients for comparison of data.

Objective: To compare accuracy and limitations of intraoperative computed tomography (iCT)- versus 3D C-arm-based spinal navigation for posterior pedicle screw implantation.

Summary Of Background Data: Despite the higher accuracy of navigated compared to non-navigated pedicle screw implantation, it remains a matter of debate whether the use of iCT imaging may further benefit navigated spinal instrumentation compared to more commonly used isocentric 3D C-arm imaging.
