Abstract

Chronic pancreatitis (CP) is a chronic progressive process which can cause irreversible damage to both the exocrine and endocrine systems of pancreas. There are various imaging modalities available to evaluate CP of which ultrasonography ( USG), computed tomography (CT), and magnetic resonance imaging (MRI) are most commonly used. USG is used as a screening modality which can show various changes of CP and its complications. However, the information obtained from USG can be limited because of the patient’s body habitus. CT is the workhorse modality which can provide comprehensive information and it is the best modality to detect calcification. MRI, on the other hand, is excellent in demonstrating the pancreatic parenchyma and the ductal system. Alcohol-related pancreatitis is the commonest cause which can show gland atrophy, ductal dilatation, and calcifications. Other less common causes include hereditary and genetic mutation–related pancreatitis. There are other special types of pancreatitis such as autoimmune pancreatitis and groove pancreatitis that have characteristic features on imaging.
