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.

A joint scintigraphy is a nuclear medical study to detect active joint disease (for example arthritis, osteomyelitis and synovitis). Joint scintigraphies are possible with different radiopharmaceuticals as 99mTc-Tc04, 99mTc nanocolloid (NC) or 99mTc-IgG. Joint scintigraphy is a procedure for a specific purpose rather than a routine test.
