Contrast-enhanced (CE) 3D T1-weighted scanning has been used more frequently with better spatial resolution and thinner section than 2D T1-weighted images for early detection and response assessment of brain metastases. To further improve the image scanning sequence, a new reconstruction algorithm, Compressed-SENSE Artificial Intelligence (CS-AI) was applied experimentally to achieve a balance between shortened scan time and improved image quality. This study aims to investigate the feasibility of contrast-enhanced 3D T1-weighted MRI reconstructed with Compressed SENSE Artificial Intelligence (CS-AI) by comparing with 3D T1-weighted images reconstructed with Compressed SENSE(CS), and to find out the optimal acceleration factor(AF).
