Lung diseases must be identified and treated in its early stages, otherwise it will lead to a serious irreversible condition. Interstitial Lung Diseases, presence of lung nodules etc. are most common but very difficult in identifying in its preliminary stages. Identification of the diseases at an earlier stage helps a lot in fast recovery of the patient. Early stage detection can be achieved by combining various detection methods to find the presence of abnormality. Advantage is that anyone in the many existing imaging systems, identifies the occurrence of the abnormality in its earlier stage. So by using different imaging schemes it is possible to identify the disease. This can be tested with available data bases and existing results. The accuracy of the same can be evaluated to a certain extent. Here the paper tries to compare existing systems that are popular for the same and introduce a combinational system that may lead to an exponential growth in the applications of medical imaging techniques. The early detection and diagnosis of lung nodules can be done with the help of medical imaging systems.
