MRIqual: A Matlab toolbox for examining the quality of structural (SNR) and functional (tSNR, SFNR) MRI

MRIqual is a Matlab toolbox that allows users to examine the quality of structural (SNR) and functional (tSNR, SFNR) magnetic resonance imaging (MRI) data. It also enables conversion of DICOM to NIfTI or Analyze (.img/.hdr) format and visualization of 3D images (slice mosaic, 3D rendering, statistical overlays). MRI quality assurance measures include multiple types of signal to noise ratio for structural and functional images, as well as temporal signal-to-noise ratio (tSNR) and Signal-to-Fluctuation-Noise Ratio (SFNR) for functional images.
