The Value Of Bronchial Artery Morphology Within Lesion In Lung Cancer Diagnosis

Methods 230 cases were examined with thin-section enhanced MSCT. Three-dimensional images of bronchial arteries were processed at the workstation. Spatial anatomical characters of the bronchial arteries using volume rendering(VR) and multiplanar reconstruction(MPR) or maxium intensity projection(MIP) were observed. Chest CT scans were analyzed retrospectively and jointly by 2 chest radiologists with 5years of experience in chest radiology. The decisions on the CT findings of the morphology of bronchial arteries were reached by consensus.The difference of the morphological characteristics of bronchial artery between lung cancer and non-neoplastic lesions test by the chi-square test.Results 193 cases were evaluated, and bronchial arteries was displayed clearly in VR. Lung cancer group 141 case bronchial arteries is display (73%), and non-lung cancer group 52 case bronchial arteries is display (27%).25 case showed thickening bronchial artery within the mass in lung cancer group and 13case showed in non-lung cancer group.92 case in lung cancer group bronchial arteries is showed thinner and 14 case in non-lung cancer.The treatment of bronchial artery slim factor reference value for the diagnosis of lung cancer by the chi-square test.Conclusion The CT angiography could visualized the features in mass clearly.The morphology of bronchial arteries in tumor to identify and demonstrate the lung cancer have a value for the diagnosis of lung cancer. Objective To evaluate the value of bronchial artery morphology within tumor in lung cancer diagnosis and the basic signs of lung cancer in central lung cancer.Method 193 case between June 2006 to February 2011,were defined as those that involved a lobar or segmental bronchus(Exclusion criteria:Heart failure caused by contrast failure. Scan range is too small doesn't meet the requirements. BA can't evaluate because of significant artifacts.The case of one side lung resection.)All case were confirmed by biopsy,surgery,diagnosis or treatment bronchoscope. All case were analyzed retrospectively and jointly by two chest radiologists with 5 years of experience in chest radiology.The feature of the lesion which include morphology, intenal structure, interface characteristics, bronchial arterial trait within the lesions, characteristics of airway wall, using volume rendering(VR) and multiplanar reconstruction(MPR) or maxium intensity projection(MIP) were observed. The decisions on the CT findings were reached by consensus. The chi-square test of the various signs used to select the factor that difference in lung cancer and non-neoplastic lesions group.The logistic regression analysis used to evaluate the value of various signs after chi-square test.Result 193 cases were examined with thin-section enhanced MSCT. Lung cancer is 124 case,and non-neoplastic lesions group is 69 case. Sign of abnormal vascular enhancement within the mass, airway wall thickening, spherical,necrosis, cavity, lobulation signs, speculation signs, pleural indentation and wide base lesions associated with pleural is displayed.There is no difference in pleural indentation sign,speculation sign in this group by chi-square test.Gender,age, thinner bronchial artery within the mass, airway wall thickening and lobulation signs in the lesion have Independent value in the diagnosis of lung cancer in this group.The sensitivity of diagnostic tests in parallel in the lung cancer diagnosis is 99.5%,and specificity is 25.13%. The sensitivity of series of diagnostic tests in the lung cancer diagnosis is 3.86%,and specificity is 99.98%. Result First, thinner bronchial artery within the mass that involved a lobar or segmental bronchus can serve as an important sign. Second,the diagnostic characters of the abnormal vascular enhancement within the mass, airway wall thickening and lobulation signs can improve the diagnostic efficiency of combined.
