Background: Quality assessment of medical images is highly related to the quality assurance, image interpretation and decision making. As to magnetic resonance (MR) images, signal-to-noise ratio (SNR) is routinely used as a quality indicator, while little knowledge is known of its consistency regarding different observers.
Methods: In total, 192, 88, 76 and 55 brain images are acquired using T, T, T and contrast-enhanced T (TC) weighted MR imaging sequences, respectively.
