Scintigraphy

Patent Pending Scintigraphy ("scint," Latin scintilla, spark) is a form of diagnostic test used in nuclear medicine, wherein radioisotopes are taken internally (via radiopharmaceuticals) and the emitted radiation is captured by external detectors (gamma cameras) to form two-dimensional[1] images. In contrast, SPECT and positron emission tomography (PET) form 3-dimensional images, and are therefore classified as separate techniques to scintigraphy, although they also use gamma cameras to detect internal radiation.
