Clinical application of dynamic CT

10 patients with primary pulmonary cancer were performed using dynamic CT scanning with dynamic curve and obtained radiograms were analized with computer. Blood is supplied usually via a bronchial artery to primary pulmonary cancer. But we could be analyzed four types on blood suppling to the primary pulmonary cancer which are via aorta, pulmonary artery, aorta and pulmonary artery and non classified type. This technique was able to suggest of effectiveness of radiotherapy with analyzing of exist of center necrosis of the tumor. Therefore we radiotherapists and radiation oncologists were able to avoid radiation-induced pulmonary pneumonia and pulmonary fibrosis especially in high aged patients. We recommended to take a this technique as preirradiative examination for patients with pulmonary cancer because of avoiding of no available radiotherapy. (author)
