The Guidance Value of Multi-slice Spiral CT Angiography to Director the Intubatton in TACE to Treat Liver Cancer

Objective To discuss the guidance value of multi-slice spiral CT angiography(MSCTA) to the intubatton in the transcatheter arterial chemoembolization(TACE).Material and Methods The hepatic arterial phase MSCTA were performed in eighty patients on a Toshiba Aquilion sixteen slice spiral CT scanner.Maximum intensity projection(MIP),volume reconstruction technique(VRT) were used to reconstruct the hepatic vessels,and to display the hepatic tumor vascular.All the cases were compared with digital substraction angiography(DSA),which compared the class of branches,origination,and configuration of hepatic artery and tumor vascular;the clamp of abdominal aorta and celiac trunk;all of these directly infect the intubatton.We would study the accord between MSCTA and DSA,And analyse the guidance value of multi-slice spiral CT angiography to director the intubatton in TACE.Results The displaying rates of the two class hepatic artery in regulation blood by MIP and VRT were respectively 97.5% and 95%.The displaying rates of MIP and VRT to three class hepatic artery were respectively 96.25%、75%.Between MSCTA and DSA,there are no significantly statistic differences in displaying two class hepatic artery;but in displaying three class hepatic artery there were significantly statistic differences between VRT and DSA;no significantly statistic differences between MIP and DSA.MSCTA display twenty cases of hepatic tumor parasitic blood supply;eighteen cases of hepatic vascular variance;comparing with DSA twenty-four and twenty-one cases,rate of positive was respectively eighty-three dot three percent and eighty-five dot seven percent.There were no significantly statistic differences in discovering hepatic tumor parasitic blood supply.The clamp of abdominal aorta and celiac trunk which MSCTA display,there were four cases straitness in arrowy planes,three cases overly left-leaning in coronary planes;all that MSCTA demonstration were all consistent to DSA.Conclusion Multi-slice spiral CT angiography can exhaustively and three-dimensionally display the anatomy origin and track of hepatic tumor vascular,and can discover the hepatic tumor parasitic blood supply,clearly display the clamp of abdominal aorta and celiac trunk,which all are highly consistent to DSA.MSCTA has a guidance value to director the intubatton in TACE.
