“…Areas of pancreatic necrosis do not show contrast enhancement. Some authors have suggested that the presence of superadded infection in acute pancreatic or peripancreatic collection may show diffusion restriction 37 ; however, this is not universally accepted, and infection is often proven by aspiration.…”

Imaging of the pancreas is often challenging because of its retroperitoneal location and unique set of pathologies. Conventional imaging modalities, such as transabdominal and endoscopic ultrasonography (EUS), computed tomography (CT), and magnetic resonance imaging (MRI), are well described in the literature. However, with modern demand for functional and molecular information from imaging studies, newer imaging modalities and modifications of existing modalities are developed. MRI is widely used as a problem-solving tool in pancreatic pathologies. Magnetic resonance cholangiopancreatography (MRCP) is an excellent technique for the depiction of the pancreatic ductal or biliary ductal pathologies. Newer modification of MRI including secretin MRCP, advanced diffusion-weighted imaging (DWI), perfusion imaging, and tissue composition analysis (fat and fibrosis quantification) add to the arsenal of MRI of the pancreas. In this review, we discuss the evolution of MRI of the pancreas and clinical application of advanced MR sequences.

“…The CT scan can determine the extent of area involved by the necrosis and can give precise details about the exact site, amount, possible communication and structures in the proximity. High resolution contrast enhancement MRI through its ability to define the composition of the necrotic collection (liquid content, necrotic sediment, clotted blood, big size debris) is useful to select the best technique for the drainage, and hence, increases the chances of effective drainage[104]. The MRI is 67% sensitive and 97% specific in detecting the presence of a superimposed infection in the pancreatic fluid collections, which gives a weaker diffusion coefficient ( P = 0.031).…”

Incidence of acute pancreatitis seems to be increasing in the Western countries and has been associated with significantly increased morbidity. Nearly 80% of the patients with acute pancreatitis undergo resolution; some develop complications including pancreatic necrosis. Infection of pancreatic necrosis is the leading cause of death in these patients. A significant portion of these patients needs surgical interventions. Traditionally, the “gold standard” procedure has been the open surgical necrosectomy, which is now being completed by the relatively lesser invasive interventions. Minimally invasive surgical (MIS) procedures include endoscopic drainage, percutaneous image-guided catheter drainage, and retroperitoneal drainage. This review article discusses the open and MIS interventions for pancreatic necrosis with each having its own respective benefits and disadvantages are covered.

“…35 Finally, DWI can also be useful in the evaluation of pancreatic/peripancreatic collections, as lower ADC values (as a result of cellular debris) can be indicative of superadded infection. 31,36 Quantification of T 2 signal using T 2 mapping (Supplementary Material 1) in acute pancreatitis has not been reported to date, but typically increased pancreatic/peripancreatic T 2 signal ( Figure 2) has the potential to yield useful quantitative markers.…”

MRI plays an important role in the clinical management of pancreatic disorders and interpretation is reliant on qualitative assessment of anatomy. Conventional sequences capturing pancreatic structure can however be adapted to yield quantitative measures which provide more diagnostic information, with a view to increasing diagnostic accuracy, improving patient stratification, providing robust non-invasive outcome measures for therapeutic trials and ultimately personalizing patient care. In this review, we evaluate the use of established techniques such as secretin-enhanced MR cholangiopancreatography, diffusion-weighted imaging, T 1, T 2* and fat fraction mapping, but also more experimental methods such as MR elastography and arterial spin labelling, and their application to the assessment of diffuse pancreatic disease (including chronic, acute and autoimmune pancreatitis/IgG4 disease, metabolic disease and iron deposition disorders) and cystic/solid focal pancreatic masses. Finally, we explore some of the broader challenges to their implementation and future directions in this promising area.

Added value of diffusion-weighted magnetic resonance imaging for the detection of pancreatic fluid collection infection

Abstract: • DW improves MR diagnostic accuracy to detect infection of PFC • Infected PFCs show lower ADC compared to non-infected ones (P < .031) • DW-MR images are easy to interpret especially for non-experienced radiologist.
