Effectiveness of contrast enhanced ultrasound examination after radiofrequency ablation liver metastasis

Purpose: Estimate of contrast enhanced ultrasound examination (CUS) after radiofrequency ablation (RFA) liver metastasis. Material and methods: 10 patients (7 male and 3 female) after radiofrequency ablation liver metastasis under CUS control using “SonoVue”. Patients age ranged from 46 to 77 years (M= 62). 9 patients had colorectal liver metastasis; one has nodular form of hepatocellular carcinoma. Prior RFA for detect and size calculation of liver metastasis standard US (Philips IU-22 Matrix) in B-mode and duplex mode had been done as well as contrast enhanced CT (GE Discovery HD750) or MRI (GE Optima MR450w).…
