GALLIUM SCAN radiographic
imaging of the body which measures the amount of the radioisotope
gallium that is concentrated in a specific part of the body.
It is most useful in detecting nodal disease above the diaphragm.
Also called: Gallium-67 scintigraphy, Ga67 scan, high dose
(8-11 mCi) gallium scan.
Key words/possible involvement: area of increased
density, area of enhanced contrast, area of high radioactivity,
space occupying lesion, diffuse nodularity, decreased uptake,
decreased activity.
Other words/no involvement: if there is no specific
reference to visible abnormality of the organs in the abdomen,
retroperitoneum, or pelvis.
PAROTID OR SALIVARY
GLAND SCAN Used to detect blockage of the salivary
gland ducts and tumors of the major salivary glands.
Key words/possible involvement: area of increased
uptake, hotspot, area of decreased uptake, cold spot,
space occupying lesion, mass, enlargement, metastases.

Other words/no involvement: if there is no specific reference
to visible abnormality, blockage or tumor, as well as references
to calcifications, vascular abnormalities, congenital anomalies,
and other benign conditions.
THYROID SCAN Also called
radionuclide scan, I-131 or I-123 scan, technetium-99m pertechnetate
scan.
Key words/possible involvement: area of decreased
uptake, cold spot, nonfunctioning nodule, area of decreased
concentration, mass, nodule, space occupying lesion.
Other words/no involvement: if there is no specific
reference to visible abnormality, normal function, size, shape,
and position, as well as references to vascular abnormalities,
benign adenomas, congenital anomalies, and other benign conditions.
