The toxic-oil syndrome (TOS) is a multisystem disorder whose etiology and pathogenesis are as yet unknown. Lung alterations persist in a significant number of TOS patients due to the underlying vascular lesion. Computer-assisted 67Ga scanning and bronchoalveolar lavage (BAL) studies were performed in 14 TOS patients with sustained abnormal diffusing capacity for carbon monoxide (Dco). No signif...

A report is presented of a liquefaction necrosis of mitral annular calcification in a patient with chronic renal failure and secondary hyperparathyroidism who had been managed by hemodialysis for 11 years. The mass was echogenic with an echo-lucent area inside, high density on computed tomography and low intensity on magnetic resonance imaging. The uptake of gallium-67 (67Ga)-citrate and the bo...

We report a case of adult T-cell leukemia (ATL) with gastric involvement visualized by 111In-chloride scintigraphy. A 55-year-old male patient presented with upper abdominal pain and appetite loss. His barium gastric series showed multiple ulcerating polypoid tumors due to gastric involvement of ATL. These lesions accumulated 111In-chloride and were also avid for 67Ga-citrate. Although the mech...

The production cross-section of 68Ge, 69Ge, 65Zn and 67Ga radioisotopes from alpha-induced nuclear reaction with natZn have been measured using the stacked foil activation technique followed by off-line γ-ray spectroscopy in incident alpha energy range 14-37 MeV. obtained cross-sections are compared previous experimental data available EXFOR library, evaluated TENDL-2019 theoretical results, ca...

This paper presents the establishment of a quality control program and correction factors for the geometry of the vials used for distribution of radiopharmaceutical and activimeters calibration. The radiopharmaceutical produced by IPEN 67Ga, 131I, 201Tl and 99mTc had been tested using two different vials. Results show a maximum variation of 22% for 201Tl, and the minimum variation was 2.98% for...
