The need for examining tissue integrity near metal implants in post-operative arthroplasty is rapidly increasing. Quantitative T2 mapping can be beneficial for characterization of tissues and early diagnosis of tissue pathology. Current T2 mapping techniques lack the capability to image near metal hardware. A novel 3D fast spin echo based two-echo multi-spectral T2 mapping technique is proposed to address this need. This technique is compared to the commercially available approach for accuracy of relaxometry measurements both in phantom and human experiments.
