Blood Biologic Half-Lives of 99mTc-NT-XI

Patient no.Half-life α (min)Half-life β (min)
145 ± 7*252 ± 31*
217 ± 4*178 ± 32*
317 ± 3*107 ± 15*
462 ± 11*383 ± 98*

  • ↵* Indicates significance (P < 0.01) of coefficients α and β.

  • Blood biologic half-lives were determined on basis of radioactivity counting in blood samples and using weighted fitting to 2-compartment model. Data are expressed as coefficient ± SE.
