PURPOSE This study systematically investigates artifacts produced by biopsy and ablation needles imaged at various trajectories with respect to the static magnetic field (B0). MATERIALS AND METHODS An acrylic phantom was scanned using a rapid balanced fast field echo sequence (FFE) with 3.0-T MRI. A 15-gauge microwave needle, a 17-gauge cryoneedle and 18-gauge coaxial-biopsy needle were imaged in sagittal and axial planes, in 7 different orientations to B0(0°-15°-30°-45°-60°-75°-90°). For four a...

Background: The aim of this study was to translate dynamic glucose enhancement (DGE) body magnetic resonance imaging (MRI) based on the glucose chemical exchange saturation transfer (glucoCEST) signal to a 3 T clinical field strength. Methods: An infusion protocol for intravenous (i.v.) glucose was optimised using a hyperglycaemic clamp to maximise the chances of detecting exchange-sensitive MRI signal. Numerical simulations were performed to define the optimum parameters for glucoCEST measureme...
