Administration in medical imaging refers to the administration of contrast agent (dye) or radioactive material (radiopharmaceutical) into the body by injection, oral administration or by other route.

An aerosol ventilation scintigraphy is a nuclear medical imaging procedure that records the distribution of an inhaled radioactive aerosol within the bronchopulmonary system.
Aerosol ventilation in the gamma camera section does not constitute a significant radiation hazard to personnel. Patient compliance is an important factor to minimizing the dose. Clear instructions and practice are a vital part of the diagnostic imaging procedure.

Amersham Health, now GE Healthcare was the imaging diagnostics and therapy business of Amersham plc. The imaging business produced contrast agents that are injected into the body to improve pictures obtained through medical imaging scans.

(ADC) An analog to digital converter is used to bridge analog and digital circuitry. Medical imaging systems use an analog to digital converter to sample and quantize the image data.

A bone marrow scintigraphy is a nuclear medical imaging procedure of the bone marrow with 99Tc-HSA-micro or nano-colloids for the early diagnostics of pathological marrow processes. The principle of this examination is the uptake of Tc-99m labeled albumin (HSA) or sulfur colloid by the reticuloendothelial cells of bone marrow. A bone marrow scan also reflects the regional blood flow. The imaging can be started 60-90 min after the injection of around 8 mCi technetium labeled colloid.
