title: A new perspective to assess relaxation time of tumor.
abstract: The dissimilarities in spin-lattice relaxation time (T1) of water proton from one tumor to the other is due to the yield of hypoxic fraction in the tumor. The yield of higher relaxation time (T1) in the KHT tumor compared to the RIF-1 tumor as a function of growth is due to the hypoxic fraction of the tumor. The hypoxic fraction in the tumor is also responsible for the P-31 spectral parameter changes.
