Tc99m-sestamibi: pembangunan kit radiofarmaseutikal untuk pemetaan jantung
A development and comparison study of the Nuclear Malaysia’s Tc99m-sestamibi heart imaging agents (NM kits) and the commercial products is reported. Three batches of kits labelled as B1, B2 and B3 were produced by freeze drying technique. The commercial products such as sestamibi Cardiolite, Polatom...

A development and comparison study of the Nuclear Malaysia’s Tc99m-sestamibi heart imaging agents (NM kits) and the commercial products is reported. Three batches of kits labelled as B1, B2 and B3 were produced by freeze drying technique.
