| BackgroundIn recent years,as the conception of Precision Medical was proposed,the research of disease diagnosis,personalized and precise treatment became a hot topic in the field of radiography.Multiple-slice spiral computed tomography has many significant advances,including fast and convenience,high image quality,high resolution,and non-invasive scanning,which has made it popular in clinical application.Nowadays there are too many research about hepatic artery,but the research that how tumors affect hepatic vein and Three-dimensional reconstruction of metastasis and cancer embolus are less.In clinical work,there are so little Three-dimensional images that MSCTA is essential and helpful to take for clinical diagnosis and treatment.ObjectivesTo study the clinical significance of this technique for liver diseases diagnosis and treatment,by using Three-dimensional reconstruction of hepatic vein and portal vein via64-slices MSCT to observe the change of diameters of all branches of hepatic vein and portal vein.MethodsA total of 255 cases including 143 patients with non-liver cancer and 112 patients with liver cancer were tested by 64-slices MSCT,who were all collected in CT department of Xinxiang central hospital from January 2014 to December 2015.The original image data of all patients were uploaded to the workstation and processed by using multi-level reconstruction,maximum intensity projection and volume reproducibility.The obtained data is carried for the three-dimensional reconstruction of the portal vein and hepatic veinon the workstation.Diameters of left,middle and right hepatic veins,hepatic portal vein,left and right branch of portal vein,splenic vein,and superior mesenteric vein were measured by using optimal cross-sectional images and multi-dimensional reconstruction images.Then some post-processing software were used to make different transparent combinations of HCC tumors,portal vein,hepatic vein and liver,and show the spatial relationships among them and also variations of hepatic vein and portal vein.Statistical analyses of the data were performed by using student's t-test via SPSS 13.0 software,measurement data was indicated as mean ± standard deviation(x ±s),P<0.05 was considered statistically significant.ResultsIn the non-liver cancer patients group,the average diameters of right,middle and left hepatic veins,hepatic portal vein,left and right branch of portal vein,splenic vein,and superior mesenteric vein were(7.4±1.6)mm,(6.3±1.3)mm,(6.8±1.4)mm,(11.7±1.8)mm,(8.4±0.9)mm,(9.3±1.1)mm,(7.8±1.2)mm,(9.9±1.5)mm,respectly.The corresponding average diameters of liver cancer patients group were(7.3±1.2)mm,(6.4±0.9)mm,(6.8±1.0)mm,(13.7±1.7)mm,(9.8±1.0)mm,(10.1±1.3)mm,(9.0±1.2)mm,(11.7±1.6)mm,respectly.The result of statistical analyses of the data by using student's t-test showed that there was not significant difference between normal patients and liver cancer patients in diameters of right,middle and left hepatic veins.However,patients with liver cancer have larger diameters in all branches of portal vein than non-liver cancer patients(P<0.05).In the male non-liver cancer patients group,the average diameters of hepatic portal vein,left and right branch of portal vein,splenic vein,and superior mesenteric vein were(12.3±1.8)mm,(8.5±0.9)mm,(9.4±1.1)mm,(7.9±1.2)mm,(10.4±1.5)mm,respectly;The corresponding average diameters of female non-liver cancer patients group were(11.6±1.7)mm,(8.2±0.9)mm,(9.1±1.1)mm,(6.8±1.5)mm,(9.4±1.4)mm,respectly.The result of statistical analyses of the data by using student's t-test showed that there was significant difference between the twogroups(P<0.05).In the male liver cancer patients group,the average diameters of hepatic portal vein,left and right branch of portal vein,splenic vein,and superior mesenteric vein were(13.6±1.7)mm,(9.9±1.1)mm,(10.3±1.3)mm,(9.1±1.4)mm,(12.2±1.4)mm,respectly;The corresponding average diameters of female liver cancer patients group were(11.5±1.7)mm,(9.0±1.2)mm,(9.5±1.3)mm,(9.0±1.3)mm,(9.1±1.4)mm,respectly.The result of statistical analyses of the data by using student's t-test showed that there was significant difference between the two groups(P<0.05).Among 255 patients,there were 20 hepatic vein variations cases and 25 portal vein variations cases,of which 15 cases were type II,8 cases were type III,1 case was type IV.ConclusionThere was not significant difference between normal patients and liver cancer patients in diameters of hepatic veins.Patients with liver cancer have larger diameters in all branches of portal vein than non-liver cancer patients.Male patients with liver cancer or non-liver cancer have larger diameters in all branches of portal vein than female liver cancer or non-liver cancer patients,which can be used to support clinical disease diagnosis. |
