This tool aims to be a comprehensive database of normal in vivo T1 and T2 relaxation parameters for a wide range of human tissues and organs. More than once I have been searching the web for normal values, and have been unable to find a single resource, so here is my best try. These parameters are only listed from peer-reviewed journal articles and are linked via their PubMed ID (PMID).

Start by typing characters into the search box to find the T1 and T2 for the region of the body (e.g., "brain", "liver", etc) that you are looking for. If there is something missing, please contact me at


Please wait.
