Lung MRI with excellent image quality has been demonstrated at 0.55T, largely due to reduced susceptibility effects. Here, we present joint estimation of lung parenchyma transverse relaxation rates $$$R_{2}$$$, $$$R_{2}^{\prime}$$$, and off-resonance $$$\Delta f$$$. A custom echo-shifted turbo spin echo (TSE) pulse sequence with ECG triggering and breath hold was performed in 4 healthy volunteers, resulting in the mean $$$R_{2}$$$ of 23.4s-1, $$$R_{2}^{\prime}$$$ of 53.9s-1, and $$$\Delta f$$$ of 45.7Hz. This work demonstrates the feasibility of echo-shifted TSE for the estimation of three parameters of interest in lung MRI, and confirms prior measurements made with separate pulse sequences.
