A patient with retroperitoneal fibrosis and right peritracheal and hilar lymphadenopathy was studied using gallium-67-citrate. No abnormal uptake was seen in the regions of retroperitoneal fibrosis, while there was avid uptake in chest lesions later shown to represent small cell lung carcinoma. Retroperitoneal fibrosis which does not show gallium uptake is most likely mature, with few inflammat...
CT and MR imaging of the brain and gallium-67 scintigraphy showed an enhancing, gallium-avid mass in the left middle cranial fossa of a 10-year-old girl. Craniotomy revealed an inflammatory mass related to the left trigeminal nerve. The lesion contained rodlike bacteria, and serologic tests were positive for cat-scratch disease. Neurologic involvement in cat-scratch disease is uncommon, and the...
Thirty-two patients with AIDS related complex (ARC) or acquired immunodeficiency syndrome (AIDS) underwent 67Ga scans as part of their evaluation. Three patterns of 67Ga biodistribution were found: lymph node uptake alone; diffuse pulmonary uptake; normal scan. Gallium-67 scans were useful in identifying clinically occult Pneumocystis carinii pneumonia in seven of 15 patients with ARC who were ...
Purpose: To identify and interrogate the role of Gallium-67 scintigraphy in the diagnosis of Sarcoidosis. Methods: A retrospective study of 75 patients with suspected Sarcoidosis in a large teaching hospital with a specialist Sarcoidosis Centre. Results: Ga-67 scintigraphy in patients considered on clinical grounds to have Sarcoidosis is a useful and sensitive test, and furthermore, by relaxing...
The value of gallium ((67)Ga) scanning in the diagnosis of septic disease of bone or joint was assessed in 34 patients. The results show a sensitivity of 60 per cent and specificity of 64 per cent. The low accuracy of this method for the detection of bone and joint sepsis (62 per cent) means that gallium scanning can be used only as an adjunct to other investigative techniques.
A 40-year-old Japanese man with acquired immunodeficiency syndrome was diagnosed with Kaposi sarcoma (KS) on the basis of the results of skin lesion biopsies. In addition, 18F-fluorodeoxyglucose-position emission tomography-computed tomography revealed abnormal fluorodeoxyglucose uptake in KS lesions, whereas gallium-67 scintigraphy did not show uptake of gallium. These findings indicate that c...
For a long time, numerous investigators dreamed of using radioisotopes to delineate a malignant tumor as a positive image. However, radiopharmaceuticals clinically sufficient for tumor detection had not yet appeared. The first suggestion, in 1969, that gallium-67( 67 Ga)-citrate might localize in tumors was based on a serendipitous finding by C.I. Edwards and R.L. Hayes.’ Although nearly 20 yea...
