“…In contrast, intense enhancement is very uncommon in pancreatic ductal adenocarcinomas due to their desmoplastic composition. They typically appear as a uniformly nonenhancing mass on CT examinations [15,16] . Therefore, these two entities may be reliably distinguished.…”

“…The outer rim of the colorectal metastasis has the same enhancement as normal pancreatic tissue, while the inner area has no enhancement at all, due to a large central necrosis. [15,16] . This points to the conclusion that large metastasis from colorectal carcinoma with central necrosis might be differentiated from primary adenocarcinoma.…”

The introduction of contrast-enhanced ultrasonography (CEUS) has led to major improvements in the diagnostic capabilities of ultrasound (US). The innovative use of CEUS for study of the pancreas has created the need for a definition of the most frequent dynamic features of solid and cystic masses. CEUS is less expensive compared to computed tomography and magnetic resonance imaging and is able to significantly improve the accuracy of US, allowing better characterization and staging of pancreatic pathologies.

“…Klinisch relevante (prognosebestimmende) Pankreasmetastasen sind selten [117,155]. Sekundäre maligne Pankreastumoren liegen in Feinnadelpunktions-und Obduktionsstatistiken bei < 10% [156][157][158][159][160] Eine Vielzahl anderer Tumoren kann im Pankreas beobachtet werden, sie sind aber selten.…”

GALLBLADDER: Ultrasound has become widely accepted for the diagnosis of gallbladder disease. Sensitivity for cholecystolithiasis is approximately 100%. Cholezystitis including its acute and chronic complications is also a domain of ultrasound techniques. An obstruction of the bile ducts and its localization are easily recognized. Clarifying the etiology is yet another question far more difficult to answer. Ultrasound contrast agents have proven to be useful for clarification of biliary tumors. Gallbladder polyps are well detectable. Adenomas of > 1 cm are an indication for surgery, the detection of a vessel at the polyps' base by color duplex ultrasound is helpful. Gallbladder carcinomas as a disease of the older age with few early symptoms are usually detected at a late stage when the liver is already infiltrated. BILE DUCT SYSTEM: Even with the most modern equipment the sensitivity for choledocholithiasis is still largely dependent on the examiner's expertise und differs between 25% and 100%. Endosonography is more efficient (94-100%). Primary sclerosing cholangitis shows bile duct dilation like "a string of pearls" and typical perihepatic lymph node enlargement. Differentiation from early cholangiocarcinoma is difficult. PANCREAS: In diagnostic imaging of the pancreas ultrasound stands at the beginning of a diagnostic cascade. In contrast to other competing examinations it can be repeated at any time and without X-ray exposure. The informative value, though, is largely dependent on the examiner's expertise. Usually, a CT scan is additionally performed when ultrasound examination is incomplete or limited through examination condition or if doubts on diagnostic accuracy arise. In cases of acute pancreatitis, especially the assessment and follow-up of complications (exudation, necrosis, pseudocysts, vascular complications, and obstructive effects) are precious. Ductal adenocarcinoma seems to be less vascularized in comparison to the surrounding tissue, while endocrine tumors and macro- and microcystic adenoma are rather hypervascularized.
