lüll Post-treatment imaging of liver tumours Schima W; Ba-Ssalamah A; Kurtaran A; Schindl M; Gruenberger TCancer Imaging 2007[Oct]; 7 Spec No A (Special issue A): S28-36In the past few years, great improvements have been made to achieve local tumour control of primary liver malignancies and liver metastases. For hepatocellular carcinoma (HCC), transarterial chemoembolisation (TACE) and tumour ablation techniques, including percutaneous ethanol injection (PEI), radiofrequency ablation (RF), and laser-induced interstitial thermotherapy (LITT) have been developed. For colorectal liver metastases, surgery is still the standard technique in localised disease, although percutaneous RF ablation has gained considerable acceptance. In patients with widespread disease, chemotherapy with new drugs offers improved survival. Contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) are the modalities of choice to evaluate treatment response. The present review demonstrates imaging findings of complete and incomplete tumour control after intervention as well as the imaging spectrum of complications. Imaging guidelines according to the World Health Organization and Response Evaluation Criteria In Solid Tumors (RECIST) for assessment of chemotherapy response are presented.|*Magnetic Resonance Imaging[MESH]|*Tomography, X-Ray Computed[MESH]|Antineoplastic Agents/therapeutic use[MESH]|Carcinoma, Hepatocellular/*pathology/therapy[MESH]|Catheter Ablation[MESH]|Chemoembolization, Therapeutic[MESH]|Contrast Media[MESH]|Humans[MESH]|Liver Neoplasms/*pathology/therapy[MESH]|Neoplasm Metastasis/diagnosis[MESH]|Neoplasm Recurrence, Local/diagnosis[MESH]|Treatment Outcome[MESH] |
