Table 2 Effective and biological half-lives determined from the mono-exponential fits to the data of radiotracer uptakes in organs and lesions in children patients

From: Patient-specific dosimetry of 99mTc-HYNIC-Tyr3-Octreotide in children

Organ Effective half-life (hour) Biological half-life (hour)
LKidney 4.72 ± 1.08 (2.44–5.93) 69.5 ± 117.1 (4.1–431.4)
RKidney 4.94 ± 1.32 (1.57–5.99) 308.5 ± 534.2 (2.1–1873.3)
Liver 5.07 ± 0.76 (3.04–5.99) 182.4 ± 429.6 (6.1–1521.6)
Spleena 5.83 ± 1.33 (4.26–8.22) 15.0 ± 42.8 (− 54.8–90.5)
Tumors 4.18 ± 1.21 (2.86–5.71) 35.0 ± 45.7 (5.4–112.9)
