Simultaneously quantifying T₂ and T₂* properties can provide great sensitivity and specificity to diseases. However, most of the existing methods are time-consuming. Here, we develop an overlapping-echo method for simultaneously achieving reliable T₂ and T₂* maps in a single shot. This method is robust to motion and the inhomogeneity of B₀. Experimental results demonstrate that the resulting T₂ and T₂* values are in good agreement with those obtained with reference methods.
