IMAGING OF INFECTION: A CORRELATIVE AND ALGORITHMIC …

Since labeled leukocyte scans show uptake by active bone marrow, it may be difficult to differentiate this normal uptake from abnormal uptake as a result of infection particularly after surgical procedures that may alter the bone marrow distribution significantly. 39 Bone marrow scans using Tc-99m sulfur colloid or nano-colloid may be added and ...

White blood cell - Wikipedia

The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count. The normal white cell count is usually between 4 × 10 9 /L and 1.1 × 10 10 /L. In the US, this is usually expressed as 4,000 to 11,000 white blood cells per microliter of blood.
