Nine patients with reflex sympathetic dystrophy were examined. Clinical manifestations suggesting arthropathy were supported by radiographic demonstration of juxta-articular and subchondral bone erosions and by radionuclide demonstration of increased activity localized in the joint regions. Aggressive demineralization was demonstrated by fine-detail(More)
A retrospective analysis was made of 25 patients with breast cancer treated only with chemotherapy in order to determine the predictive value of technetium-99m bone scanning in determining response to chemotherapy. Whole-body scanning demonstrated bone healing in only 3 of 25 patients. However, the presence of stable disease on bone scan correlated with a(More)
In spite of localization of gallium in the lungs in a large variety of inflammatory pulmonary diseases, the chest radiograph is and will continue to be the principal diagnostic tool for evaluation of pulmonary inflammatory disease. The 67Ga-citrate scan, however, serves as a study complementary to chest radiography because it indicates the extent,(More)
Nodules were found in 1108 subjects who received childhood radiation for benign conditions of the cervical area at our institution. This is 37.5% of 2958 subjects, out of a total of 5379, for whom there is follow-up information. Of the 848 subjects who have had thyroidectomies, 297 (35.0%) had thyroid cancer. In addition to thyroid tumors, salivary, neural,(More)
Patchy osteoporosis is the primary roentgenologic manifestation of the reflex sympathetic dystrophy syndrome (RSDS). As recent clinical and histologic data suggested articular changes in RSDS, fine-detail roentgenograms were obtained in eight consecutive patients. Juxta-articular and soft-tissue swelling, osteoporosis and erosions of the subchondral bone(More)
Radiogallium uptake in the salivary glands is strongly correlated with prior therapeutic radiation which includes the cervical region. Fifteen of 17 patients with increased salivary gland uptake had such a history. An easily identified characteristic pattern of symmetric localization of 67Ga occurs in the parotid and submandibular regions in these patients.(More)
This review is based primarily on historic data, and it examines the indications for and limitations of gallium-67 scanning in the evaluation of patients with neoplasms. The use of gallium-67 scans is discussed according to tumor type, and data from the most representative and comprehensive studies are included. The results described, some of which were(More)
Gallium-67 scans were performed on 32 patients with adult and childhood sarcomata as part of clinical staging studies. Gallium-67 scans proved to be highly accurate in assessing sites of disease in patients with malignant schwannoma, Ewing's sarcoma, and rhabdomyosarcoma. Gallium-67 scans were inaccurate in determining sites of disease in patients with(More)
Of 5379 patients who had received radiation treatment at our institution for benign conditions of the head and neck, 318 developed thyroid cancer 3 to 42 years later. We report follow-up observations (median interval from diagnosis to recurrence or last contact, 10 years; longest interval, 31) for 296 of these patients. Three patients died of thyroid cancer(More)
