A gallium-67/technetium-99m subtraction technique was used with a variable weighting factor. That is, each image was separately set to 100%. Varying amounts of the Tc-99m images were subtracted from those of Ga-67. A total of 95 patients who had radiogallium scanning for suspected inflammatory
Gallium citrate scanning at 6 hr was used to evaluate a patient with active ulcerative colitis. The localization of 67Ga in the colon correlated with the extent of the inflammatory process. When either colonoscopy or radiographic contrast studies are contraindicated, 67Ga scanning at 6 hr may prove
The treatment of acute nonspecific pericarditis is controversial. No study is available that confirms the efficacy of the administration of corticosteroids or nonsteroid anti-inflammatory agents in this condition. There is no reliable invasive marker for pericardial inflammation, because
OBJECTIVE
The purpose of this study was to compare the inflammatory activity of pulmonary lesions between active tuberculosis and nontuberculous mycobacterial (NTM) infection in acid-fast bacilli smear-positive non-HIV-infected patients using gallium-67 (Ga) scintigraphy.
METHODS
Twenty-four
Central venous catheter-associated Nocardia bacteremia is rarely reported. We present the case of a 48-y-old male with a history of advanced T-cell lymphoma who suffered from recurrent fever and persistent Gram-positive bacillus bacteremia. Port-A catheter-associated Nocardia bacteremia was
Gallium scintigraphy was performed in 54 consecutive patients hospitalized for exploration of fever or inflammation of unknown origin, in whom thorough initial exploration did not yield any clue. Only in 28 patients (51.8%) could a definite diagnosis be established. The positive gallium scintigraphy
The mechanism of ionic gallium-67 localization in inflammatory lesions was studied. Human polymorphonuclear leukocytes (PMN) had higher Ga-67 uptake than lymphocytes, whereas red blood cells had no affinity for Ga-67. Uptake by PMN showed temperature dependence, was independent of Ga-67
The clinical features in patients with acute Q fever are variable. We present a patient with fever, abdominal distension, pericardial effusion, and diffuse gallium uptake in the abdominal cavity, mimicking peritonitis or peritoneum carcinomatosis. Serologic surveys revealed acute infection by
The differential gallium-67 (67Ga) accumulation in tumors and inflammatory lesions in rats after i.v. injection of liposome encapsulated 67Ga ([67Ga]liposomes) was studied. The 67Ga accumulation in the tumor was much greater than that in the granulation tissue regardless of the surface charge of
OBJECTIVE
The purpose of this study was to evaluate the efficacy of gallium-67 ((67)Ga) scanning in the differentiation of malignant tumors from benign tumors or inflammatory disease in the oral and maxillofacial region. Study design Fifty-two patients with tumors or inflammation in the oral and
Gallium 67 has been found to be extremely useful for detection of inflammatory disease. In the skeletal system it complements the 99m Tc-phosphate compounds in differentiating periatricular osteomyelitis, septic arthritis, and cellulitis. Gallium is particularly useful in documenting successful
An 8-yr-old boy with a 1-mo history of culture-negative fever and anemia underwent gallium, ultrasound, and computed tomography studies as part of the evaluation of a fever of unknown origin. These studies revealed a mobile gallium-avid solid abdominal mass subsequently proven to be an inflammatory
Gallium arsenide (GaAs), a technologically and economically important semiconductor, is widely utilized in both military and commercial applications. This chemical is a potential health hazard as a carcinogen and immunotoxicant. We previously reported that macrophages at the exposure site exhibit
This study aimed to investigate the impact of organic gallium (OG) on osteoporotic fracture healing in ovariectomized female Sprague-Dawley rats, as well as study the mechanisms of OG on osteoporotic fracture healing. Forty-five female Sprague-Dawley rats were divided into three groups: sham
Background: Inflammation is an essential response provided by the immune system, ensuring the survival during microbial infection, tissue injury and other noxious conditions. However, prolonged inflammatory processes are often associated with severe side effects on
