Conventional two-dimensional (2-D) texture parameters serve as the "gold standard" of texture analysis. The authors compared a new stochastic model, based on autoregressive periodic random field models (APRFM) with conventional texture analysts (CTA) parameter, which were defined as measures of the co-occurrence matrix, i.e., entropy, contrast, correlation,(More)
Squamous cell carcinoma of the liver arising from a non-parasitic cyst is a rare entity of a primary liver tumor with an unfavourable prognosis. We report a case of a patient with a cyst in the right lobe leading to upper abdominal symptoms and respiratory discomfort. Malignancy was not suspected from the clinical findings or repeated cytological(More)

BACKGROUND Biliary complications are significant source of morbidity after liver transplantation (LT). Cholangiography is the gold standard for diagnosis and specification of biliary complications. OBJECTIVES Detailed analyses of ultrasound (US) as a safe imaging method in this regard are still lacking. Therefore we analyzed systematically the diagnostic(More)
BACKGROUND Hepatic artery embolisation (HAE) in patients with hereditary haemorrhagic telangiectasia (HHT) is controversial because of the associated complications and unproven long-term benefit. We present our results in 20 such patients over a time span of 17 years. METHODS Staged HAE was performed using polyvinyl alcohol (PVA) particles and coils.(More)
Being the biggest inner organ of humans, the liver contributes decisively to metabolism. Hereby, liver activities result from reactions on ingestion and digestion and are assumed to influence the acoustical properties of the liver tissue. In this work we present initial results of the investigation of aforementioned reactions by observing the liver in-vivo(More)
