The liver tumors represent a major public health issue. Among the imaging techniques, ultrasonography remains an important diagnostic method, taking into consideration its large availability, the non-invasive and repetitive characteristics and the low cost. Its current limits can be surpassed, at least at some extent, by using some new techniques such as the 3D ultrasonography. 3D ultra-sonography provides several advantages: increases the efficiency

Diseases of the biliary and pancreatic ducts are often difficult to diagnose. Although transcutaneous ultrasonograpy, computer tomography and magnetic resonance greatly improved in performance, two major problems have not been completely solved yet: first, the differentiation of malignant and benign bile duct strictures, and, second, the assessment of the resectability of carcinomas underlying biliary strictures. Ultrasound probes can be inserted

Endoscopic ultrasonography (EUS) is a diagnostic method that aims to detect and stage tumors of the pancreas more accurately. It has a high predictive role regarding tumor resectability. Aim. The present paper aims to assess the diagnostic accuracy of radial EUS in the staging of pancreatic cancer as well as the role of EUS to predict tumor resectability. Material and methods. 30 patients (22 males, 8 females, mean age 61 ± 12 years) with pancreatic

Hepatocellular carcinoma is one of the five most common cancers worldwide. Experimental and clinical data indicate that in human hepatocellular carcinoma (HCC) tumor progression is associated with angiogenesis and that an increase in microvascular density is associated with a poor prognosis. Ultrasound is an attractive modality for imaging angiogenesis because of the ease with which it can be repeated without exposing the patient to any risk. The

Hepatocellular carcinoma (HCC) is one of the neoplasic diseases that meet the requirements to become the target of surveillance in a screening program: it is a frequent condition; it has a high rate of mortality; it affects a very well defined at risk population (chronic liver diseases patients). This population can be closely followed-up using an ultrasonography method (US). Therefore, the improvement of the screening and surveillance system for

The purpose of this study is to characterize the evolution of the liver diseases towards hepatocellular carcinoma (HCC), by finding the relevant textural features obtained from ultrasound images, which accurately surprise the changes of the liver tissue in the context of this evolution. For the computation of the textural features, the following methods are used: first and second order statistics, edge-based statistics, fractal-based methods and

The study aimed to identify the presence of steatosis and differentiate between insignificant and significant steatosis in non-alcoholic fatty liver disease (NAFLD). Thirty three patients with NAFLD proven by liver biopsy and evaluated in order to stratify the degree of steatosis were studied. The computerized processing of the data of the ultrasonic image (attenuation coefficient - LS7 slope), and a biological marker (adiponectin) were evaluated.

We report the prevalence, histological aspect, endoscopic treatment and follow-up of colonic polyps of 2 cm or larger and of laterally spreading tumors (LSTs) in an eastern European country. Methods. All consecutive colonoscopies carried out over a 1-year period (3,856) in the Endoscopy Department of the 3rd Medical Clinic Cluj-Napoca were evaluated. Fifty-two polyps and 12 LSTs of ? 2cm diameter were found. Size, location and histological aspect

Ultrasonography is a simple method in diagnosing nonalcoholic steatohepatitis (NASH), providing useful information, but it is subjective and does not accurately differentiate between steatosis grades. The computerized processing of the data that comprises the ultrasonic image might transform ultrasonography into an objective examination. We aim to study the performance of the quantitative evaluation of the ultrasound beam behavior into the liver

The purpose of this study is to find the relevant features in order to detect the forerunner and early stages of the hepatocellular carcinoma (HCC); thus, we aim to characterize the evolution of the liver diseases towards hepa-tocellular carcinoma (HCC), by detecting the relevant textural features obtained from ultrasound images, which accu-rately surprise the changes of the liver tissue in the context of this evolution. For the computation of the
