Abstract:

WB-DWMRI and PET-CT are the two functional tools available for detection and staging of cancer patients. PET-CT has been the established modality since last two decades however with the improvements in MRI technology it is now possible to perform a whole body functional and anatomical imaging. This article reviews the current literature to determine whether WB–DWMRI can be an alternative imaging to PET-CT for imaging cancer patients. The study reviewed 19 studies from 2009-2016 for all types of regional and metastatic cancers including lymphomas and myelo infiltrative disorders to determine the sensitivity and specificity of both the imaging modalities. The results of these studies are discussed and these showed a comparable sensitivities and specificities. The study concludes that due to inherent advantages of WB-DWMRI i.e. lack of radiation, time saving, no use of contrast and lower cost it can be considered as an alternative imaging tool in the evaluation of such patients.
