CT Scan
The purpose of a CT scan is to detect the following;
- Disease extent - CT scan is useful in determining the extent of disease, particularly in lesions of the oral cavity, tongue, and esophagus.
- Assessment of metastasis - to determine the extent of metastasis to regional lymph nodes.
- Perineural invasion - for lesions that are in close proximity to nerves, especially for tumors in the oral and nasopharyngeal cavities.
The accuracy of nodal staging with a CT scan is better than clinical staging, and is helpful in determining which treatment modalities to use.
Advantages:
- CT is less expensive than an MRI.
- CT is more sensitive in detecting tumor involvvement of the bone and cartilage.
- CT is safer for patients with implants.
Disadvantages
- Exposure to radiation.
- Less sensitive for soft tissue involvement.[1]
