Radiological Characteristics, Imaging Techniques and Staging of Lung Cancer

Lung cancer is among the most common cancers worldwide accounting to significant morbidity and mortality. Patients suspected of having lung cancer undergo various diagnostic procedures. Chest X-ray, positron emission tomography, computed tomography and magnetic resonance imaging are used for the diagnosis although combination of computed tomography and positron emission tomography are considered to be more effective and reliable imaging techniques. Lung cancer staging framework provides with better information of the disease and guides in planning treatment modalities. The purpose of this research is to review the available information about the radiological characteristics, imaging techniques and staging of lung cancer. The lung staging has three salient characteristics, tumour, node and metastasis also staging play a critical role in diagnosis and treatment plan. Combination of computed tomography and positron emission tomography undoubtedly improve the mediastinum nodal stage and reduce the number of ineffective interventions thus considered the most productive imaging method. Complete staging should be performed along with the computed tomography in lung cancer patients as a considerable volume growth, a measure of malignancy, has been demonstrated to positively connect with a minimum diameter rise over time. Quality treatment depends on the accurate staging among lung cancer patients. The significance of radiological characteristics, staging and imaging techniques of lung cancer is highlighted in literature through various studies and research although more clinical trials in future can be beneficial.
