Electronics Nuclear engineering description: Acute myocardial infarcts (AMI) are typically discriminated with T2-weighted short TI inversion recovery (STIR) with turbo spin echo (TSE) readouts [1], albeit with limited specificity [2]. Guided by the association that T2-STIR images identify AMI territories on the basis of edema-related T2 changes, even some of the recently proposed improvements [2,3] have relied on preferential sensitization of magnetization to T2- weighting. However, whether T2-STIR imaging itself may also be sensitive to other sources of image contrast have not been fully investigated. We hypothesize that in addition to T2-weighting, edema detection with T2-STIR imaging has substantial weighting from proton density (PD) changes. date: 2010 type: Conference or Workshop Item type: PeerReviewed identifier: Zhou, Xiangzhi and Rundell, Veronica and Liu, Ying and Tang, Richard and Klein, Rachel and Giri, Shivraman and Shah, Saurabh and Tsaftaris, Sotirios A. and Zuehlsdorff, Sven and Simonetti, Orlando and Li, Debiao and Dharmakumar, Rohan On the origin of myocardial edema contrast in T2-STIR images.
