Gamma scintigraphy allows non-invasive visualisation of drug formulations and body systems. A gamma emitting radiopharmaceutical is incorporated into the formulation before administration allowing images to be acquired at precise intervals over a period of time. Analysis of these images provides qualitative and quantitative information on formulation behaviour in vivo. In addition to routine 2 dimensional techniques, scintigraphy can be applied 3 dimensionally.

Gamma scintigraphy is also routinely used to investigate the residence of nasal and oesophageal formulations and to study the deposition of pulmonary formulations. Bio-Images has extensive experience in designing suitable labelling techniques for new formulations and delivery systems. We would be happy to discuss other applications of this technology.
