Image acquisition
Images were acquired periodically after oral administration of
radiolabeled rifampicin and radiolabeled rifampicin nanoparticles under
gamma camera at various time intervals (0h,1h, 2h, 7h, 12h, and 24 h
post-administration) to study the distribution of radiolabeled
rifampicin nanoparticles inside the body. Images were acquired on a
SPECT/CT gamma camera equipped with high energy collimator. A standard
of known activity (~200 μ Ci in 50 ml syringe) was
placed at the lowest uptake area and was imaged with the patient.
