CT

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 involvement of the bone and cartilage.
• CT is safer for patients with implants.

Disadvantages

• Exposure to radiation.
• Less sensitive for soft tissue involvement.
