Feasibility of relaxation along a fictitious field in the 2nd rotating frame (TRAFF2) mapping in the human myocardium at 3 T
Myocardial <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub><mml:mrow><mml:mtext>T</mml:mtext></mml:mrow> <mml:mrow><mml:mi>RAFF</mml:mi> <mml:mn>2</mml:mn></mml:mrow> </mml:msub> </mml:math> quantification at 3 T was successfully achieved in a single breath-hold with acceptable image quality, albeit with residual off-resonance artifacts. Nonetheless, preliminary clinical data indicate potential sensitivity of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub><mml:mrow><mml:mtext>T</mml:mtext></mml:mrow> <mml:mrow><mml:mi>RAFF</mml:mi> <mml:mn>2</mml:mn></mml:mrow> </mml:msub> </mml:math> mapping to myocardial infarction detection without the need for contrast agents, but off-resonance artifacts mitigation warrants further investigation.
