Objective To evaluate DSA feature, the value, efficacy and side effect, survival time of microcathereter superselective catherization intervenetional treatment on liver metastases cancer. Methods 60 cases with liver metastases cancers were cannulated through common femoral artery by seldinger technique. If the artery was lack, second radiography was given through superselective hepatic artery. On the base of DSA feature of liver metastases, all the patients were divided into two groups: superselective- catherization group and nonsuperselective-catherization group. There were 30 patients in each group respectively. Microcathereter was used in the former to "embed" the tumor vessel and "siphonal" technique was used in the later. Compared the changes of the two groups in volume, the deposit of iodized oil in liver matastases after treating one month and the changes of ALT, ALB, TBIL in blood. The efficacy and side effect were compared in two groups. The survival time and DSA feature of using microcathereter were also analyzed. Results The DSA feature and efficacy of superselective-catherization group was better than that of non-superselective-catherization group, the side effect was mild and the survival time was longer than the former. Conclusion Microcathereter superselective catherization to treat liver metastases cancer has better efficacy, artery radiography, lighter side effect and can prolong the survival time.

Objective:To investigate the value of MRI and MSCT in TNM staging of laryngocarcinoma.Method:Thirty-seven patients with laryngocarcinoma were underwent by contrast enhanced scan and muhiplanar reconstruction.Thirty-five patients with laryngocarcinoma were underwent contrast enhanced muhislice spiral CT,which of them were done by MPR.There are 28 cases which were scan by MRI and MSCT in the two former nd we contrasted the accuracy rating in laryngeal manifestation of abnormality.In the former two groups,we observed them the variability in the aspect of lymphaden metabasis and TNM staging.Result:In all 28 cases,the MRI had better accuracy rating in displaying the parts of preepiglottic space,larynx side interspace,lingual root,eck tissue,vocal cord.In the TNM staging,there was no difference in stage one in accuracy rating,as the stag stepping up,the accuracy rating of MRI had became better.The last result was that the two methods had difference in staging.In the two methods,MSCT had better sensitivity,specificity and accuracy rating.Conclusion:RI and MSCT had good accuracy rating in TNM staging,MRI has better accuracy rating in some of laryngeal,but as the lymphaden metabasis,the MSCT was better.There were variability in staging,and the MRI was better.

OBJECTIVE: To investigate the value of MRI and MSCT in TNM staging of laryngocarcinoma. METHOD: Thirty-seven patients with laryngocarcinoma were underwent by contrast enhanced scan and multiplanar reconstruction. Thirty-five patients with laryngocarcinoma were underwent contrast enhanced multislice spiral CT, which of them were done by MPR. There are 28 cases which were scan by MRI and MSCT in the two former and we contrasted the accuracy rating in laryngeal manifestation of abnormality. In the former two groups, we observed them the variability in the aspect of lymphaden metastasis and TNM staging. RESULT: In all 28 cases, the MRI had better accuracy rating in displaying the parts of preepiglottic space, larynx side interspace, lingual root, neck tissue, vocal cord. In the TNM staging, there was no difference in stage one in accuracy rating, as the stag stepping up, the accuracy rating of MRI had became better. The last result was that the two methods had difference in staging. In the two methods, MSCT had better sensitivity, specificity and accuracy rating. CONCLUSION MRI and MSCT had good accuracy rating in TNM staging, MRI has better accuracy rating in some of laryngeal, but as the lymphaden metastasis, the MSCT was better. There were variability in staging, and the MRI was better.
