this indicates that 31p-nmr spectroscopy data have to be supplemented with other data , e.g. , rate of oxygen consumption , cell survival time under hypoxic stress , and/or fraction of metabolically active , nonclonogenic hypoxic cells , to be useful in quantitative determination of tumor hypoxia and hence prediction of tumor radioresistance caused by hypoxia .
