Thyroid Cancer Staging: An Overview
- The size of the tumor
- Whether the disease has spread, and if so, to what parts of the body.
Thyroid Cancer Staging Tests
Tests and procedures that may be used in thyroid cancer staging include:
- Ultrasound
- Computed tomography (CT) scan
- Magnetic resonance imaging (MRI)
- Radionuclide scan (diagnostic I-131 whole body scan).
Ultrasound
An ultrasound is a procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes will then form a picture of body tissues called a sonogram.
Computed Tomography (CT) Scan
A CT scan is a procedure that makes a series of detailed pictures of areas inside the body that are taken from different angles. A computer that is linked to an x-ray machine makes these pictures. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly on the scan. This procedure is also called computerized tomography or computerized axial tomography (CAT).
