Abstract:
Imaging guidance techniques for percutaneous ablation could be provided by fluoroscopy, US,CT and MR.The choice between them offen depends on the skill and preference of the operator and also the availability.CT can provide accurate three dimensional(3D)anatomical information,contrast enhancement will better delineate the lesion and assess its vascularity and 3D restruction techniques would further highlight the surrounding vascular structure and organs in order to prevent damages during puncture.MSCT is thus eminently suitable for percutaneous tumor ablation guidance procedures,including pure ethanol injection (PEI),microwave coagulation therapy(PMCT),interstitial laser photocoagutation(ILP),radio-frequency(RF), electrochemotherapy(ECHT)and so on.In recent years,CT-guided radioactive seed implantation technique in treating lung tumor,pancreatic cancer and metastasis was reported with good clinical effects of minimal damage and few complications.Some investigators reported that there were no significant differences in the tumor necrosis rate,cumulative recurrence and cumulative survival rate between PEI alone and PEI combined TACE for small tumor,however,combined therapy of PEI and TACE has better efficacy in treatment of tumor larger than 3 cm compared to only one therapeutic technique.Therefore,combination of interventional therapies may be more suitable for treatmemt of larger tumors.(J Intervent Radiol,2007,16:793-795)
