T 2 Quantification Using Only T 2 -weighted and Proton Density Weighted Fast Spin Echo Images

Proton density and T ₂ -weighted fast spin echo images are frequently acquired in clinical MRI exams. T ₂ quantification is commonly performed in the clinic via applying an exponential fit to these two images, despite recent evidence that an exponential fit is insufficient to correctly quantify T ₂ . We present T ₂ quantification by implementing stimulated echo compensated T ₂ fitting using only a proton density-weighted and a T ₂ -weighted fast spin echo image. This method is demonstrated in the human brain in comparison to a standard quantitative multi-echo spin echo approach.
