PDFAbstract
Objective To investigate the application value of contrast-enhanced multislice spiral CT (MSCT) in judging the feasibility of excision of lung cancer. Methods The contrast-enhanced MSCT images of 68 patients with non-small cell lung cancer (NSCLC) diagnosed by operation or biopsy in our hospital from August 2014 to August 2016 in were retrospectively analyzed and were compared with results of operation. Results The coincidence rates of contrast-enhanced MSCT in evaluating pulmonary hilar and mediastinal great vessel invasion and mediastinal lymph node metastasis with the results of operation were 86.76% and 83.82%, the consistency was satisfying (Kappa=0.68, 0.61), the sensitivities were 77.78% and 80% respectively, the specificities were 90% and 86.05% respectively. The coincidence rate of contrast- enhanced MSCT in evaluating feasibility of excision of NSCLC with the results of operation was 79.41%, the consistency was satisfying (Kappa=0.57), sensitivity was 85.37%, and specificity was 70.37%. Conclusion Contrast-enhanced MSCT can reflect the invasion of blood vessels and mediastinal lymph node metastasis, providing objective data for the doctors to judge the resectability of NSCLC.
