Apples or Kiwis? Is 23Gy kidney absorbed-dose limit the way to go for radiopharmaceutical therapies?
Переглядів 644Рік тому
Clinical trials for radiopharmaceutical therapies (RPTs) are usually limited to 23 Gray absorbed dose to kidneys. However, this value seems arbitrary when considering its source: a publication for external radiation beam therapy (EBRT) dating back to 1991, itself referring to a paper in 1968. The existing limit in fact neglects inherent differences between RPT and EBRT. In this episode, Nuclear...

Myth or Fact? We Cannot Perform Routine Dosimetry For Radiopharmaceutical Therapies
Переглядів 1,1 тис.2 роки тому
Radiopharmaceutical therapies have shown great promise to treat different disease such as prostate cancer and neuroendocrine tumors. Currently, however, they follow a population based approach in which every patient is treated the same. Can we move into personalizing radiopharmaceutical therapies? That would involve performing routine internal dosimetry. In this episode, Nuclear Jimmy and invit...
