Hemangiosarcomas are commonly associated with toxic exposure to thorium dioxide ( Thorotrast ), vinyl chloride, and arsenic.
12.
He also contributed to the development of Thorotrast for use in the procedure and contributed many lectures and papers on the subject.
13.
In the form of Thorotrast, a thorium dioxide suspension, it was used as contrast medium in early X-ray diagnostics.
14.
German patients exposed to Thorotrast had their median life-expectancy shortened by 14 years in comparison to a similar non-exposed control group.
15.
The risk of developing bile duct cancer ) in former Thorotrast patients has been measured to be well above 100 times the risk of the rest of the population.
16.
Historadiography has also been used to visualize staining of tissue, such as spinal cord samples with thorotrast, which contains thorium that is opaque to X-rays.
17.
Historically, contrast media was sometimes highly dangerous but these dangers were not well-understood during the development of the early types of contrast media, such as Thorotrast.
18.
Among other things, the scientists are studying the effects of thorotrast, a radioactive substance that at one time was injected into patients to aid in medical diagnoses of brain tissues.
19.
Radiologic contrast medium, has been linked to the development of cholangiocarcinoma as late as 30 40 years after exposure; Thorotrast was banned in the United States in the 1950s due to its carcinogenicity.
20.
Unfortunately, some elements chosen proved to be harmful for example, thorium was once used as a contrast medium ( Thorotrast ) which turned out to be toxic, causing a very high incidence of cancer decades after use.
