“…Rickes et al evaluated the accuracy of CEUS for the diagnosis of AP severity, considering CE-CT as the reference method, and they found out that CEUS had 82% sensitivity (Se), 89% specificity (Sp), 95% positive predictive value (PPV), and 67% negative predictive value (NPV) for diagnosing severe AP, with a much lesser cost than CE-CT [15]. Similar results were obtained by other authors, CEUS Se and Sp ranging from 86 and 97%, respectively [16], to 90.3 and 98.8%, respectively (97.4% accuracy) [17].…”

Transabdominal ultrasound (US) is the first-line imaging method used to diagnose pancreatic lesions, but contrast techniques are needed to differentiate among inflammatory and malignant lesions, as well as between pseudocysts and cystic tumors. Contrast-enhanced (CE) ultrasonography has been proven to be a useful tool in this regard with performance similar to contrast-enhanced computer tomography/magnetic resonance imaging (CT/MRI), being also safer and nonirradiant. According to the EFSUMB guidelines on the nonhepatic use of contrast-enhanced ultrasound (CEUS), this method is useful to improve characterization of ductal adenocarcinoma; to differentiate between pseudocysts and cystic tumors; to differentiate vascular (solid) from avascular (liquid/necrotic) components of a lesion; to better define the dimensions and margins of a lesion, including its relationship with adjacent vessels; and to help the choice for a next imaging technique.

“…Una vez que el riñón ha sido identificado (transductor posicionado medialmente), el duodeno puede ser visualizado adyacente a la pared abdominal. Alternativamente, el páncreas puede ser detectado por la vena pancreático duodenal, que se encuentra paralela al duodeno descendente (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13).…”

This study describes the ultrasonographic techniques currently used in the evaluation of the canine pancreas. Ultrasonography was the first method to enable direct visualization of the pancreas in humans and it has been subsequently applied to animals. Currently, it is the method of choice for pancreatic evaluation and is essential as a diagnostic tool in the detection of abnormalities, especially tumors. Innovative equipment technology has led to the emergence of techniques complementary to B-mode ultrasound; such as Doppler, elastography, and contrast-enhanced ultrasonography, which have enabled more accurate diagnosis. Doppler provides information on vascular architecture and the hemodynamic aspect of blood vessels in multiple organs. ARFI elastography provides detailed images of the alterations detected by conventional examination (qualitative method) and assists in differentiating between benign and malignant processes (quantitative method). Microbubble contrast agents determine parameters related to homogeneous and heterogeneous filling of organs with microbubbles, mainly nodular areas, thus defining high and low intensity patterns. Keywords: B-mode, Doppler, elastography, microbubbles (Source: CAB). RESUMENEste estudio describe las técnicas ecográficas frecuentemente utilizadas para evaluar el pancreas del perro. La ecografía fue el primer método que permitió la visualización directa del páncreas en seres humanos y que luego se aplicó en animales. Es actualmente el método de elección para la evaluación del páncreas y es esencial como herramienta diagnóstica en la detección de anomalías, especialmente tumores. La tecnología innovadora de los equipos, llevó a la aparición de técnicas complementarias al modo B, tales como Doppler, elastografía, ecografía de contraste, que han permitido realizar diagnósticos más precisos. El Doppler proporciona información sobre la arquitectura vascular y aspectos hemodinámicos de los vasos sanguíneos en múltiples órganos. La elastografía ARFI ofrece imágenes detalladas de las alteraciones detectadas en exámenes convencionales (método cualitativo) y ayuda a diferenciar entre procesos benignos y malignos (método cuantitativo). Los agentes de contraste con microburbujas permiten determinar parámetros relacionados con el llenado homogéneo o heterogéneo de los órganos, principalmente áreas nodulares, definiendo, por tanto, patrones de alta o baja intensidad.Palabras clave: modo B, Doppler, elastografía, microburbujas (Fuente: CAB).

“…Some Authors have described that a low MI at CEUS shows hyperenhancement in focal and diffuse autoimmune pancreatitis and allows the differential diagnosis with ductal adenocarcinoma (which does not hyper-enhance). 66 Role of pancreatic endoscopic ultrasound EUS represents a new mild invasive technique of imaging that combines the advantages of B-mode ultrasound with those of endoscopy. Thanks to the proximity of EUS transducer to the organs of interest, the images obtained are frequently more accurate and more detailed than the ones obtained by traditional ultrasound.…”

Acute pancreatitis is an inflammatory disorder of the pancreas characterized by abdominal pain and elevation of pancreatic enzymes in the blood. The pathogenesis is complex and partly unknown and the evolution is often unpredictable. Many efforts have been made to define this disease and its complications and to classify different grades of severity in order to formulate prognostic scores that could guide the physician in choosing the optimal therapeutic setting and procedures. The management of the patient with pancreatitis is not always optimal and differs among internist, gastroenterologist or surgeon. We think that a patient with clinical suspicion of acute pancreatitis is admitted to medical or surgical department depending on the availability of beds and not according to evidence-based medicine. The aim of this monograph is to identify the optimal management of patients with acute pancreatitis admitted to hospital.

Contrast-enhanced ultrasound in the staging of acute pancreatitis

Abstract: CEUS is comparable to CT in detecting pancreatic necrosis as well as predicting its clinical course. Therefore, when CT is contraindicated CEUS may be a valid alternative.
