ABSTRACT
Objective To investigate the treatment values of precise target delineation of chest MRI for lung cancer Methods From August 2011 to February 2015 , 45 non-small cell lung cancer patients were given chest CT scans and MRI scans before radiotherapy , and then active target tumor delineation , then related influencing factors were analyzed. Results All patients completed CT scans and MRI positioning. For patients that it was difficult to identify lung tissue lesions caused by lung cancer through CT , their MRI imaging showed high signal and the boundaries between the tumor and surrounding normal tissue became relatively clear. Meanwhile , 20 patients of borders were diagnosed by CT , while 25 by MRI; 36 patients with lymph node metastasis were diagnosed by CT while 40 by MRI. The difference was statistically significant (P<0.05). Univariate logistic regression analysis showed that pathological type and atelectasis were the influence factors for CT and MRI tumor target delineation differences (P<0.05), and multivariate logistic regression analysis showed the atelectasis was the main factor (P<0.05). Conclusion Compared with CT, breast MRI can precisely delineate target to improve the accuracy of target localization before radiotherapy. It can help determine lymph node metastasis and avoid the impact of atelectasis then ensure the accuracy of radiotherapy.
