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 myelography is a radiographic imaging procedure to visualize the spinal canal, the spinal cord, cerebrospinal fluid (CSF), intervertebral disks and nerve roots. A special contrast agent (dye) is injected through a needle into the subarachnoid space of the spinal canal. A myelogram provides a very detailed picture of the spinal cord and spinal column. A fluoroscopy displays the bones and the fluid-filled space of the spine also in motion. An additional computerized tomography (CT or CAT) scan helps to differentiate the spinal conditions better. The indications include disc herniation, spinal stenosis, tumor, and vertebral fracture.

Whole body scintigraphy is the measurement of radioactivity in the entire body.
Whole body scintigraphy is useful for example in detection of tumors, infections, evaluation of metastases, and diseases with multiple organ involvement.
Different whole body scan techniques include:
