Hepatoma Induced by Thorium Dioxide
Southern Medical Journal, 1976A 74-year-old man complained of anorexia and weight loss. Twenty-six years earlier he had received an injection of Thorotrast. A needle biopsy of the liver showed thorium dioxide granules and periportal fibrosis. On laparotomy, a hepatoma of the left lobe of the liver was discovered.

Patients who have received thorium dioxide (Thorotrast) are at risk for hepatic and other malignancies. Because of the need to identify and carefully follow up these patients, we have presented three cases with the characteristic radiologic findings on plain films so that physicians unfamiliar with this appearance will now be aware of it.

The cohesion of thorium dioxide
Journal of Physics: Condensed Matter, 1994The cohesion of solid thorium dioxide is calculated within the fully ionic description, calculating exactly, after generating the electronic wavefunctions of the ions, those parts of each inter-ionic potential that do not arise from electron correlation.

Thorium Dioxide and Liver Cancer
JAMA: The Journal of the American Medical Association, 1982To the Editor.— In light of recent data presented at the International Conference on the Radiobiology of Radium and the Actinides in Man held in Lake Geneva, Wis, Oct 11-16, 1981 (co-sponsored by the US Department of Energy, the US Nuclear Regulatory Commission, and the Commission of European Communities), the following additional comments are offered

LATE EFFECTS OF THORIUM DIOXIDE IN MAN
Archives of Internal Medicine, 1951THE USE of thorium dioxide in man has been controversial since its introduction in 1930. 1 In the form of a colloidal suspension, thorium dioxide is a radiopaque diagnostic agent of greatest usefulness in visualizing the liver and spleen. Numerous observers have shown that this particulate material is taken up by the reticuloendothelial system after ...

Thorium-thorium dioxide phase equilibria
Journal of Nuclear Materials, 1969Various Th-ThO2 mixtures were investigated with thermal analysis, X-ray, and microscopic techniques. The following information on phase boundaries is deduced. The oxygen solubility in solid Th is less than the OTh ratio of 0.003. The solid-solid transition of Th saturated with ThO2 occurs at 1370 ± 30 °C.

Progressive Thorium Dioxide Myelopathy
New England Journal of Medicine, 1964THIS seems to be an era of steadily increasing use of many contrast mediums in an effort to study and diagnose various problems. This practice is increasing in all branches of medicine but especially in delineating the nervous system and its vascular supply. This is good, and certainly none can detract from the great advances in neurologic surgery that

Thorium-Dioxide Granuloma With Laryngeal Palsy
Archives of Otolaryngology - Head and Neck Surgery, 1970A case is presented of associated laryngeal paralysis due to thorium dioxide (Thorotrast) granuloma of the neck. This was caused by accidental extravasation at the time of carotid angiography 20 years previously. Phonosurgical repair was successful.

Thorium-dioxide-inducedpharyngeal hemorrhage
American Journal of Otolaryngology, 1983Thorium dioxide, a producer of alpha particle radiation, was used in the United States from 1930 to 1950 for carotid and cerebral angiography. Cervical thorium dioxide granuloma is a well-recognized sequela of extravasation of this material near the carotid bifurcation.

Biokinetics and assessment of intake of thorium dioxide
Radiation Protection Dosimetry, 2003The aim of this work was to investigate the biokinetics of thorium dioxide in animals for the purpose of assessing intakes of the compound by workers and the resulting doses. The results imply that measurements of the decay products in the chest or extrapolations from urine analysis data are unlikely to be of value for doses below 20 mSv.
