Computed Tomography Image under Artificial Intelligence Algorithm to Evaluate the Nursing and Treatment Effect of Pemetrexed Combined Platinum-Based Chemotherapy on Elderly Lung Cancer

Figure 5

Changes in lung cancer CT images before and after chemotherapy. Male, 79 years old, patient with lung cancer. (a) Before chemotherapy, the CT image showed the distribution of nodular soft tissue density masses at the posterior and lower right hilum (the size was about 0.8 cm in diameter, the edges were slightly under-rectified, and there was no obvious swollen lymphoma in the mediastinum). (b) After chemotherapy, CT images showed that the posterior and lower right hilum nodules were significantly smaller than before treatment, with a diameter of about 0.4 cm, blurred edges, reduced right lung volume, and no obvious lymphadenopathy in the mediastinum.
