ABSTRACT
Objective To explore the correlation between dual energy imaging indices,microvessel densi-ty(MVD),vascular endothelial growth factor(VEGF)and lung cancer lymph nodes metastasis and its practical sig-nificance by applying dual source CT(DSCT)dual energy imaging.Methods 62 cases of non-small cell lung can-cer(NSCLC)were underwent DSCT dual energy imaging and divided into groups with and without lymph node me-tastasis according to the results of pathology.The expressions of MVD and VEGF were detected as well.All the indi-ces were compared between the two groups. Results(1)The differences between the lung cancer lymph node groups in the iodine concentration,normalized iodine concentration(NIC),spectrum curve of arterial phase,MVD and VEGF were statistically significant(P<0.05).(2)The iodine concentration,NIC and spectrum curve of arte-rial phase were positively correlated with MVD and VEGF.Conclusion Iodine concentration,NIC,and spectrum curve of arterial phase of DSCT dual energy imaging can be regarded as part of the important indices for preopera-tive diagnosis of lymph node metastasis of NSCLC.
ABSTRACT
Objective To study the curative effect of CT-guided percutaneous acetic acid injection(PAI)combined with transcatheter arterial chemoembolization(TACE)in the treatment of primary heaptocellular carconima.Methods 52 cases with primary heaptocellular carconima were divided into two groups.26 cases were treated with TACE and PAI,combined group comparing with other 26 cases treated with TACE group.Results Decrease of AFP,shrinkage of tumor mass and survival rate of 1-2 years of the combined group and TACE group were 78.3% vs 50.0%,65.4%(17/26) vs 38.5%(10/26)and 73.1%(19/26),52.6%(10/19) vs 57.7%(15/26),33.3%(5/15),respectively;with statistical significance(P
