Quantitative T2 mapping in the presence of metal implants is affected by susceptibility-related artifacts. We propose a low flip angle view angle tilting-enabled turbo-spin echo sequence along with spatiotemporal undersampling for low SAR scan efficient T2 mapping. The proposed technique would allow 2.5min T2 mapping with high temporal sampling of the T2 relaxation curve. Performance of the proposed technique is evaluated using retrospective under-sampling simulations and phantom experiments using a cobalt-chromium hip arthroplasty implant.
