RESUMEN
Objective To evaluate the examination of non-small-cell lung (NSCLC) vein formation and the dynamic characteristics of blood stream through enforced SCT scanning for the research on and clinical diagnosis of tumor.Methods Double period enhanced SCT scanning was done to 152 NSCLC cases identified pathologically.Makes the color coding the tumour blood stream irrigation chart,the analysis blood stream irrigation characteristic.Compare the enforced morphologic manifestation of cancer focus with histology and analyze their pertinence.Results The enforced CT peak value (PV) of the low differentiation is bigger than that of the medium differentiation,which is bigger than the high differentiation.63 cases are 45-70 HU,78 cases are 20-45 HU and 11 cases are 10-20 HU.67 case are of abnormal arteriola; 23 cases are of abnormal hemal sinus development; 35 cases are pistil-like.Conclusion Accurately examining and quantifying cancer focus vein formation according to SCT double period enforced scanning is of high guiding value in the enactment of the plan for treating NSCLC and the comprehensive treatment of tumors.
