Researchers developed a new radiotracer called FDT for PET scans to specifically target live TB bacteria.
This method offers a more precise way to identify active TB infection in the lungs compared to current methods.
Existing methods include sputum tests (which can miss ongoing infection)
The new approach developed by the researchers is more specific as it uses a carbohydrate that is only processed by the TB bacteria
This new approach is promising for low- and middle-income countries due to:
Fewer technical requirements (uses existing PET scanners)
Simpler production process (doesn't require specialized facilities)
These advantages are crucial as these countries see the majority of TB cases globally.
Positron emission tomography (PET) is a type of nuclear medicine procedure that measures metabolic activity of the cells of body tissues.
PET is actually a combination of nuclear medicine and biochemical analysis.
A positron emission tomography (PET) scan is an imaging test that can help reveal the metabolic or biochemical function of your tissues and organs.
The PET scan uses a radioactive drug called a tracer to show both typical and atypical metabolic activity.
