Possibilities of contrast- enhanced ultrasound (CEUS) for evaluation of the success of percutaneous treatments of malignant liver lesions using special perfusion software

Aim: Using new perfusion software for evaluation of the success of percutaneous treatments of malignant liver tumor lesions with CEUS. Material and methods: Retrospective analysis of 79 patients (66 male, 13 female; 30 – 84 years) with 140 malignant liver lesions (size 9 mm-10 cm). The lesions were metastases in 45 cases and HCC lesions in 95 cases. The success of percutaneous interventional treatments (IRE n = 40; RFA n = 33; MWA n = 36; TACE n = 31) was evaluated by CEUS with perfusion imaging using special perfusion software. CEUS was performed after bolus injection of 1 – 2.4 ml of sulfur hexafluoride microb…
