Area of Science:

  • Nuclear medicine
  • Radiopharmaceutical chemistry
  • Biomedical imaging

Background:

  • Yttrium-87 (87Y) and its daughter strontium-87m (87mSr) are radioisotopes with potential applications in nuclear medicine.
  • Effective preparation of radiotracers is crucial for accurate biodistribution studies.

Purpose of the Study:

  • To prepare Yttrium-87 (87Y) in an injectable form.
  • To determine the biodistribution of 87Y-EDTMP in Balb/c mice.
  • To evaluate the suitability of 87Y as a tracer for clinical investigations involving Yttrium-90 (90Y).

Main Methods:

  • Preparation of 87Y and its daughter 87mSr in a radiochemically pure form suitable for intravenous injection.
  • Biodistribution study of 87Y-EDTMP in a Balb/c mouse model using appropriate imaging or counting techniques.

Main Results:

  • Yttrium-87 (87Y) was successfully prepared in a form suitable for injection.
  • The biodistribution of 87Y-EDTMP was determined in Balb/c mice, providing data on its distribution and retention in vivo.
  • The results indicate that 87Y is a viable radiotracer for preclinical and potentially clinical studies involving 90Y.

Conclusions:

  • The successful preparation and biodistribution analysis of 87Y-EDTMP demonstrate its potential as a radiotracer.
  • 87Y serves as a suitable tracer for future clinical investigations, particularly those focusing on therapies or diagnostics involving 90Y.
