Overview
CT scan may be helpful in the diagnosis of anaplastic thyroid cancer.
Key CT Findings in Anaplastic thyroid cancer
- A CT scan uses special x-ray equipment to make 3-dimensional and cross-sectional images of organs, tissues, bones and blood vessels inside the body. A computer turns the images into detailed pictures. It may be used to:[1]
- Help determine the location and size of the thyroid tumour (although ultrasound has become the preferred imaging test for this purpose)
- Check organs and surrounding tissues for any spread of the cancer
- Check lymph nodes surrounding the thyroid for spread of the cancer (if the lymph nodes are enlarged)
- Precisely guide a biopsy needle into areas where the cancer is thought to have spread
- A CT scan can detect cancer that has spread and developed into tumours in others parts of the body. It cannot detect cancer cells that have spread but have not yet developed into tumours (microscopic spread).
- Sometimes intravenous contrast medium is used with a CT scan to provide a more detailed image. The contrast may sometimes not be used if it is suspected that the person has a differentiated thyroid cancer because it can interfere with radioactive iodine scans and treatment.
