Diagnosis of Non-Small Cell Lung Cancer

Imaging Studies for Non-Small Cell Lung Cancer

Imaging studies are performed to determine the extent of the non-small cell lung cancer (NSCLC) and to complete the staging workup. In general, the following imaging studies are performed:

• Chest X-ray - This is usually the initial radiological (imaging) test performed to determine if there are any abnormalities in the lungs.

• Computed tomography (CT Scan) - This imaging modality can define the location, size, and anatomical characteristics of a tumor much better than a regular chest X-ray.

• Magnetic resonance imaging (MRI) - This imaging modality is useful for determining if a tumor has spread to involve a nerve or bone.

• Positron emission tomography (PET) scan - This is a new imaging modality that is becoming more widely used in staging lung cancer. It is essentially a "whole body" scan so that it can also detect if a tumor has spread to other parts of the body.

• Bone scan - This imaging test is used to determine if lung cancer has spread to the bones.
