Tissue was taken from 16 patients with benign thyroid lesions (10 nontoxic nodular colloid goiter, two follicular adenoma, one autonomous adenoma, one iodine-induced thyrotoxicosis, 2 Graves' disease) and 18 patients with malignant thyroid tumors [seven papillary, five follicular, five undifferentiated (anaplastic), and one medullalry carcinoma] and was(More)
Sonography and NMR imaging of the knee joint make it possible to obtain a visual representation of the thickened synovial membrane occurring in patients with rheumatoid gonarthritis, even before inflammatory deformation is radiologically detectable. Both methods can expose effusions and Baker's cysts. In NMR imaging, an indication of the inflammatory(More)
The importance of lightmicroscopical and immunohistochemical features of 38 recurrent differentiated thyroid carcinomas (27 papillary carcinomas (PC), 11 follicular carcinomas (FC] for post-operative serum thyroglobulin (TG) concentrations was analysed in regard to pre-operative serum TG levels with tumour type, histological and cytological differentiation,(More)
In a retrospective study, the hematologic parameters of 296 patients treated with iodine-131 (average: 536 mCi) for carcinoma of the thyroid gland were evaluated with respect to the different doses applied. The average observation period was 65 months. The most frequent hematologic modification was thrombocytopenia which was found in 35%, followed by(More)
59 post-therapeutic examinations of the bone marrow have been performed in 35 patients out of a group of 296 patients treated from 1969 through 1976 by postoperative iodine-131 irradiations for carcinoma of the thyroid gland. Seven patients had normal findings, twelve patients showed panmyelopathy as principal finding, and fourteen patients presented(More)
The new HIDA derivative, 99mTc-dimethyl-iodine-HIDA (JODIDA), was compared with 99mTc-diisopropyl-HIDA (DISIDA) in 17 patients with jaundice by means of paired cholescintigraphic imaging studies. The following parameters were visually assessed: the extent of urinary tract visualization, biliary contrast and appearance time, and gallbladder visualization and(More)
