Purpose: To determine whether optical imaging can be used for in vivo therapy response monitoring as an alternative to radionuclide techniques. For this, we evaluated the known Her2 response to 17-dimethylaminoethylamino-17-demethoxygeldanamycin hydrochloride (17-DMAG) treatment, an

Generator-derived radionuclides for PET/CT imaging are promising for optimizing targeted radiotherapy by an individual patient-based approach, applying pre-therapeutic evaluation, as well as dosimetric calculations, and for measuring treatment response after radionuclide therapy.

Peptide receptor radionuclide therapy (PRRT) consists of the systemic administration of a synthetic peptide, labeled with a suitable β-emitting radionuclide, able to irradiate tumors and their metastases via internalization through a specific receptor (usually somatostatin S2), over-expressed on the cell membrane. After almost 2 decades of experience, PRRT, with either (90)Y-octreotide or (177)...

introduction foodstuffs are known to contain natural and artificial radionuclides. determination of radionuclide concentration is of great significance for the protection of human health. the main objective of the present study was the quantification of radionuclides in tea samples, cultivated in guilan province in north of iran. materials and methods the activity concentrations of 226ra, 232th...

BACKGROUND the characteristics of (90)Y, suitable for therapy, are denoted by the lack of γ-emission. Alternative methods, using analogues labelled with (111)In or (86)Y, are generally applied to image (90)Y-conjugates, with some inevitable drawbacks. New generation SPECT/CT image systems offer improved Bremsstrahlung images. The intent of this brief communication is to show that high quality (...
