| SPECT |
Single-photon emission computed tomography. A special type of computed tomography (CT) scan in which a small amount of a radioactive drug is injected into a vein and a scanner is used to make detailed images of areas inside the body where the radioactive material is taken up by the cells. SPECT can give information about blood flow to tissues and chemical reactions (metabolism) in the body.

| spectroscopy |
The study of the interaction between matter and radiation. Since the energy levels in all atoms and molecules are discrete (quantized), the absorption or emission of radiation occurs at distinct energies (frequencies) characteristic of a given chemical. The energy levels probed may be rotational (microwave region), vibrational (infrared region), or electronic (visible or ultraviolet). ...
