Abstract:
Objective To discuss the applied value of MSCT in the interventional treatment of hepatic metastases (HMs). Methods 23 cases HMs were treated by interventional treatment before it MSCT plain scan was performed first,and then dual-phase dynamic contrast-enhanced scanning and reconstruct angiography. Results 78 lesions were found by plain scan,and 102 lesions in the arterial phase and 105 lesions in the portal venous phase were found by contrast-enhanced scan,dynamic contrast-enhanced CT scanning was superior to detecting lesion of diameter <1cm (P<0.05). CT scanning showed that plain scan showed low-density foci; and according to the number of enhanced lesions,enhancede scanning showed enhancement for the edge of the ring,diffuse enhancement,heterogeneous enhancement,and no enhancement respecfly. Vascular remodeling showed that all eases could show the hepatic artery three grade below through MSCTA,eompletely conformed to the DSA,the indication rate was 100%;14 cases could show the hepatic artery four grade above,with 60.9% indication rate. Portal vein showed that all cases could show the branches of intrahepatic portal vein four grade below through MSCTA; DSA hepatic arteriography could show the portal vein indirectly,but most of the intrahepatic branches three grade below couldn't show clearly. Conclusion MSCT dynamic contrast-enhanced scan could improve the detection rate of HMs,and dynamic contrast-enhanced scanning was superior to the detection rate then plain scan,high-qulity imagy of hepatic artery and portal vein could be reconsructed by fast dynamic contrast-enhanced scanning,and compared with DSA,it had the advantage of operat more easily and non-invasive,so as be a guide in the interventional treatment of HMs.
