gallium

/gal·li·um/ (Ga) (gal´e-um) a chemical element, at. no. 31. The nitrate salt is an inhibitor of bone calcium resorption and is used to treat cancer-related hypercalcemia.

gallium Ga 67 citrate  a radiopharmaceutical imaging agent used to image neoplasms, particularly of soft tissues, and sites of inflammation and abscess.

gallium (Ga)

[gal′ē·əm]

Etymology: L, Gallia, Gaul

a metallic element. Its atomic number is 31, and its atomic mass is 69.72. The melting point of gallium is 29.8° C (88.6° F); it will melt if held in the hand. Because of its high boiling point (1983° C; 3602° F), it is used in high-temperature thermometers. Radioisotopes of gallium are used in total body scanning procedures. Many of its compounds are poisonous.

gallium-67

a radioisotope of gallium having a half-life of 78.1 hours; used in the imaging of soft tissue tumors.

gallium nitrate

used in the treatment of hypercalcemia.

gallium scan

a nuclear medicine procedure using the radioisotope gallium-67 in the form of gallium citrate. Gallium has a high affinity for certain tumors and also for non-neoplastic lesions, such as abscesses. Gallium scans are particularly useful in the staging of lymphomas, and in localizing occult abscesses.
