Question

39) The half-life of "Mo used in the "Mo-e generator is A. 78 hours B. 13.2 hours C. 73 hours D. 66 hours 71) The molecular targeting method of tissue localization for 11-Satumomab pendetide (OncoScinct C in ovarian and colo-rectal cancer imaging is A. active transport C. capillary blockage D. antigen-antibody reaction 72) Te-DTPA is compound formed fromTe and DTPA forn A. Colloid B. Phosphonate C. Chelate D. Antibody

Answer 1

39. Option D is the answer .The half life of 99Mo used in the 99Mo -> 99mTc generator is 66 hours . Mo has a half life of 66hours and can be easily transported over long distances to hospitals where it's decay product technetium is extracted and used for various nuclear medicine diagnostic procedures.

71. The molecular targeting method of tissue localisation for 111In -satumomab pendetide in ovarian and colorectal cancer imaging is antigen -antibody reaction

72. 99mTc- DTPA is a chelate compound formed from 99mTc and DTPA . It is a compound containing a ligand bonded to central metal atom at two or more points .
