single photon emission computed tomography quantitation of Gallium Citrate uptake for the differentiation of lymphoma from benign hilar uptake
Journal of Clinical Oncology, 1995Co-Authors: E Evensapir, Rachel Barshalom, Ora Israel, Alex Frenkel, Galina Iosilevsky, Nissim Haim, Ron Epelbaum, Diana Gaitini, Gerald M Kolodny, Dov FrontAbstract:PURPOSETo assess the role of quantitative Gallium Citrate (Ga 67) single-photon emission computed tomography (SPECT) in differentiating lymphoma from benign hilar uptake, concentrations of Ga 67 in 29 sites of documented lymphoma and in 75 benign lesions were compared.PATIENTS AND METHODSOne hundred seven thoracic Ga 67 SPECT studies obtained in 101 consecutive lymphoma patients were reviewed. Fifty-nine studies detected Ga 67 uptake in the hilar and or mediastinal regions. Forty-eight studies showed no such abnormality. The concentration of Ga 67 in the thoracic lesions was measured using a quantitative SPECT technique and its nature was determined by correlation with computed tomographic (CT) scans and follow-up evaluation of the sites.RESULTSIn 20 of 59 abnormal studies (34%), there was lymphoma in the hilar and or mediastinal regions. In the remaining 39 abnormal studies (66%), Ga 67 uptake was benign. There were 29 sites of lymphoma and 75 benign lesions. The concentration of Ga 67 in lymphoma was si...

hepatorenal polycystic disease and fever diagnostic contribution of Gallium Citrate ga 67 scan and fluorine f 18 fdg pet ct
European Urology, 2011Co-Authors: Julio Jimenezbonilla, R Quirce, Emilio Rodrigo Calabia, Ignacio Banzo, I Martinezrodriguez, J M CarrilAbstract:A cyst infection was suspected in a patient who was on haemodialysis for renal failure secondary to hepatorenal polycystic disease with persistent fever and pain in right hypochondrium despite antibiotherapy. Radiologic exams (ultrasonography, computed tomography [CT]), however, did not show signs of infection. For surgical removal of the infected cyst, a precise location was required. This report shows how functional imaging, Gallium Citrate Ga 67 scan, and fluorine F 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) revealed which cyst was infected; however, the fused image provided by PET/CT showed the precise, required location. The infected cyst was located on the right kidney. A week later, after nephrectomy, all symptoms disappeared.

lacrimal gland uptake of 67ga Gallium Citrate correlates with biopsy results in patients with suspected sarcoidosis
Ocular Immunology and Inflammation, 2014Co-Authors: Bradford Tannen, Anton M Kolomeyer, Roger E Turbin, Larry Frohman, Paul D Langer, Nasrin Ghesani, Lionel S Zuckier, David S ChuAbstract:AbstractPurpose: To investigate whether lacrimal gland uptake on 67Ga-Gallium Citrate scintigraphy correlates with histopathologic evidence of sarcoidosis.Methods: A retrospective, pilot study of 31 patients with suspected sarcoidosis who underwent Gallium scintigraphy and lacrimal gland biopsy. Lacrimal gland Gallium uptake was assessed by subjective visual scoring (SVS) and lacrimal uptake ratio (LUR).Results: Eleven (36%) patients had lacrimal gland biopsies containing noncaseating granulomas. A statistically significant correlation was found between lacrimal gland Gallium uptake and biopsy positivity using SVS (p = 0.03) or LUR (p = 0.01). Using SVS, biopsy positivity rate increased from 0 to 50% in patients with mild to intense uptake. Using LUR, biopsy positivity rate increased linearly as the ratio increased from 13% (LUR 8).Conclusions: Lacrimal biopsy positivity rate significantly correlated with Gallium uptake on scintigraphy. Both SVS and LUR methods appear to correlate with...
