These are broadly divided into non-small cell carcinoma and small cell carcinoma as they differ clinically regarding presentation, treatment, and prognosis: most common cell type in non-smokers but still most patients are smokers, most common primary lung malignancy to cause paraneoplastic syndromes and SVC obstruction. Performance evaluation and generalisability of an AI algorithm for lung For example, it can show if you are anemic (have a low number of red blood cells), if you could have trouble with bleeding (due to a low number of blood platelets), or if you are at increased risk for infections (because of a low number of white blood cells).

The evaluation of distant metastasis (in particular of the liver and the adrenal glands) is the rationale behind including the upper abdomen in the staging CT. When the CXR raises the suspicion for malignancy, CT with contrast should be performed for complete staging.
