Abstract
Image-guided HCC tumor ablation provides curative treatment in properly selected patients or appropriate therapeutic options whenever surgical techniques are precluded. Tumor response assessment post ablation is important in determining treatment success and future therapy. Computed Tomography (CT) and Ultrasound (US) play important roles in patients‘ follow-up post liver thermal ablation therapies.
The aim of this study was to evaluate the role of computed tomography for evaluation and follow up of hepatocellular carcinoma after Microwave ablation.
This prospective study was carried out on 30 patients radiologically proved with hepatocellular carcinoma, in the Diagnostic Radiology and Medical Imaging Department at Tanta University Hospitals and Liver Institute at Kafr-Elsheikh.
The main results of the study revealed that: ● Triphasic CT imaging arterial phase revealed homogenous enhancement lesions in 46.7% of patients and heterogeneous enhancement in 53.35% of patients. All the lesions showed early washout in portovenous and delayed phases with patent portal vein in all patients. ● The diameter of ablated area was different according to duration of ablation. The applications of 60 W for 8-10 minutes produced ablation zones with a size of 3.5-4 x 4.7-5.2cm while applications of 60 W for 10-15 minutes produced ablation zones with a size of 4.5 - 5.5 x 5.6-6.5 cm. ● Triphasic CT was performed after 1 month and revealed that the success rate was 93.8% for tumors measuring ≤ 3cm 92.9% for tumors measuring 3-5cm.
