Purpose:To analyze relative factors of radiation pneumonitis (RP) and investigate the relationship between the features of HRCT and prognosis of RP. Materials and methods:Analysis of HRCT Manifestations in 86 cases suffered from RP in 580 patients who received radiation therapy for chest tumors as to related to prognosis. Results: Seven relative factors of RP were sumed up. According to appearance of HRCT,RP could be classified into fours types: type of patch and exudation, type of consolidation, and type of atelectasis and fibrosis.
