In previous Q&A's we have illustrated how MR signal intensities on T2(*)-weighted DSC images decrease during passage of a gadolinium bolus. From this raw data some potentially useful semiquantitative parameters can be extracted, such as time-to-peak (reflecting blood flow) and negative enhancemen...
