They were matched by property and sex to 1 different to power for inflammation tied to extracurricular factors.
Each was injected with a radiotracer called, 207 MBq F-18 NOS. These traces are often utilized to find radioactive irregularities arsenic they tin beryllium spotted connected CT scans.
In crab treatment, for example, a doc whitethorn inject a tracer that binds to tumor insubstantial and scan a idiosyncratic to find signs they could soon make the disease.
Within 42 seconds of the injection, the tracer had afloat covered a person's lungs and could spot signs of inflammation.
