In SNR assessment of phantom MR images, the noise level cannot be obtained from the background areas reliably when a parallel imaging technique is used. The current gold standard is to use a difference image for noise assessment on the object. In practice the difference image methods are prone to artifacts from position drifts and solution flow. We present a method for SNR measurement from one image only, based on the wavelet transform. The new method is validated using the difference image method.
