“…An extrapancreatic finding can be assessed on the basis of the CT scan (cholecystolithiasis, choledocholithiasis, vein thrombosis and ascites) or other abnormalities in the abdominal cavity. MRI provides very similar results [14][15][16][17] .…”

Diagnosis and treatment of acute pancreatitis is a complex interdisciplinary team problem. Without knowledge of classification and the current opinion of other experts on this disease, the radiologist cannot be an adequate partner in this team. Nonetheless, the radiologist has a very important position, primarily ‘thanks to’ computed tomography (CT) in diagnosis and fading of the disease and the possibilities offered by minimally invasive treatment of early and late complications of this disease. A turning point from the viewpoint of diagnosing acute pancreatitis was first marked by Balthazar’s classification and then establishing the CTSI (severity index for the disease based on CT findings), proposed by Balthazar as well. Radiologists’ increasingly more active approach to drainage of acute fluid collections and pseudocysts in patients with acute pancreatitis as well as some possibilities for percutaneous treatment of necroses has led to a reassessment of surgeons’ attitudes. A persistent problem is the correct indication and timing of CT scans and the drainage itself. In their concise communication, the authors present data from the literature and summarize their own experience. They highlight the most common mistakes, especially in the indication and timing of individual methods. Finally, they present their views on a practical approach to the use of CT and percutaneous drainage in these patients.

“…(1) T1-weighted imaging with fat suppression improves the delineation of pancreatic borders and the pancreas itself, and it additionally has important value in evaluation of pancreatic hemorrhage and hemorrhagic complications of acute pancreatitis [7,8] ; (2) T2-weighted imaging has significant advantage in demonstrating fluid-filled lesions in or around the pancreas and the pancreatic ducts. Fat-suppressed T2-weighted imaging is additionally helpful for evaluating the mild forms of acute pancreatitis [18,20] ; and (3) MRCP has an excellent capability of allowing noninvasive evaluation of pancreatic ducts, side-branches and the whole extrahepatic biliary tract, and it provides few respiratory artifacts or susceptibility effects [7] . Furthermore, after the intravenous administration of contrast agent, the dynamic contrast-enhanced MRI (e.g.…”

“…Advantages for using MRI in patients with acute pancreatitis are as follows: (1) it is a diagnostic imaging method without radiation hazard; (2) it is particularly useful in patients who cannot receive iodinated contrast material owing to allergic reactions or other contraindications; (3) MRCP has the unique capability of providing noninvasive images of pancreatic parenchyma and pancreatic duct integrity, and it has the advantage of demonstrating possible communication of a pancreatic pseudocyst with pancreatic ducts [8,15] ; (4) MRI has a potential advantage over CT in detecting bile duct lithiasis and pancreatic hemorrhage of pseudocysts or pseudoaneurysm, which can help plan surgery; (5) nonenhanced MRI seems to be more accurate and reliable for the early assessment of severity and prognosis of acute pancreatitis than is contrast-enhanced CT [12,16,17] ; and (6) non-enhanced MRI is superior to CT for depiction and confirmation of mild forms of acute pancreatitis [18] . Nevertheless, there are several limitations for using MRI in this disease.…”

Acute pancreatitis is characterized by acute chemical injury of the pancreatic parenchyma and peripancreatic tissue. The increased frequency of death in acute pancreatitis is directly correlated with the degree and progress of pancreatic necrosis. Moreover, the occurrence of some local complications in acute pancreatitis, such as pancreatic hemorrhage, peripancreatic abscess or large pseudocyst, and pseudoaneurysm, could influence the choice of treatment for these patients. Magnetic resonance imaging (MRI) can be used to help evaluate the presence and degree of pancreatic necrosis, and is crucial for identifying complications of acute pancreatitis and predicting prognosis. The purpose of this article is to describe MRI techniques for acute pancreatitis, to review the spectrum of pancreatic and peripancreatic patterns, as well as to survey various complications secondary to acute pancreatitis on MRI. The role of MRI in the initial evaluation and staging of acute pancreatitis is emphasized.

“…In patients in whom the diagnosis is unclear, as the signs of acute pancreatitis are unequivocal on CT and many other acute abdominal processes can also be detected using this method. There is some evidence, however, that MR imaging may be slightly superior in this subgroup of patients [63]. 2.…”

“…Magnetic resonance imaging is comparable to CT in its capacity to diagnose acute pancreatitis and to provide precise information regarding the severity of the disease [47,63,64]. The MRI findings using T2-weighted sequences and contrast enhanced T1-weighted sequences are comparable to CT and therefore an analogous terminology may be applied (Figs.…”

Acute pancreatitis is defined as an acute inflammatory process of the pancreas with variable involvement of peripancreatic tissues or remote organ systems. This article reports the current classification, definition and terminology, epidemiology and etiology, pathogenesis and pathological findings, clinical and laboratory findings, and finally imaging findings of acute pancreatitis with emphasis on cross-sectional imaging modalities such as ultrasound, computed tomography, and magnetic resonance imaging.
