Overview
CT scans help stage the lung cancer. A CT scan of the abdomen and brain can help visualize the common sights of metastases: adrenal glands, liver, and brain. CT scans diagnose lung cancer by providing anatomical detail to locate the tumor, demonstrating proximity to nearby structures, and deciphering whether lymph nodes are enlarged in the mediastinum.
CT Scan
- Chest CT scan may be helpful in the diagnosis of lung cancer. Findings on CT scan suggestive of lung cancer include:[1]
- Solitary pulmonary nodule
- Centrally located masses
- Mediastinal invasion
- Peripherally situated lesions invading the chest wall
- A ground-glass opacity
- Consolidation
- Mixed density or pure ground glass nodules
- Mixed density or pure ground glass consolidation
- CT scans help stage the lung cancer. A CT scan of the abdomen and brain can help visualize the common sights of metastases: adrenal glands, liver, and brain.
- The benefits of CT Scans in lung cancer patients are the following:[2]
- Provides anatomical detail to locate the tumor
- Demonstrates proximity to nearby structures
- Deciphers whether lymph nodes are enlarged in the mediastinum
Unfortunately, research has shown that there are a number of false positives associated with CT scanning because a CT scan on its own cannot determine malignancy. A positive result for a tumor using a CT scan is typically followed up with a biopsy for confirmation. Images courtesy of RadsWiki
