Transverse relaxometry with transmit field-constrained stimulated echo compensation.
Purely exponential decay is rarely observed in conventional mono-exponential T2 mapping due to transmit field inhomogeneity and calibration errors, which collectively introduce stimulated and indirect echo pathways. Stimulated echo correction (SEC) requires an additional fit parameter for the transmit field, resulting in greater uncertainty in T2 relative to mono-exponential fitting. The aim of this study was to develop an accurate and precise method for T2 mapping using SEC. ⋯ The proposed method generates reliable and reproducible quantitative T2 maps and should be considered for future relaxometry studies.
