The basis of pulmonary scintigraphy is the detection of gamma rays emitted from the lung after administration of a radioactive tracer.

The cerebral blood pool can be imaged with single photon emission computed tomography (SPECT) and positron emission computer tomography (PET) techniques. The used radiopharmaceuticals are technetium-99m labeled red blood cells (RCBs) for SPECT and O-15 labeled water for PET imaging. Measured can be cerebral blood volume, brain perfusion and cerebral metabolism.

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:
