Pancreatitis is the inflammation of the pancreas, a gland located behind the stomach that produces enzymes for digestion and hormones like insulin. When the pancreas becomes inflamed, these digestive enzymes can activate while still inside the pancreas, irritating its cells and causing swelling and pain. The condition can be acute, appearing suddenly and lasting for days, or it can be chronic, developing over many years. While it can be a serious condition, many cases are mild and resolve with supportive care.
Symptoms of acute pancreatitis often include gradual or sudden pain in the upper abdomen that may radiate to the back, sometimes accompanied by fever, nausea, and vomiting. In many instances, the condition is first identified when a person seeks care for this severe abdominal pain. Common causes include gallstones blocking the bile duct and heavy alcohol consumption, though in some cases, the specific cause may not be identified. Chronic pancreatitis may present with similar symptoms or may only be discovered after it has led to other issues like weight loss or digestion problems.
An MRI is a powerful, non-invasive imaging tool that plays a key role in evaluating the pancreas. It provides detailed pictures of the gland, its ducts, and the surrounding tissues without using radiation. For pancreatitis, an MRI can help identify the presence of inflammation, detect gallstones, assess the extent of any damage to the pancreas, and visualize complications such as fluid collections (pseudocysts) or blocked ducts. This detailed view helps doctors confirm the diagnosis, understand the severity of the condition, and plan the most appropriate course of action.

Frequently asked questions
What is the difference between acute and chronic pancreatitis?
Acute pancreatitis comes on suddenly and usually lasts days. Chronic pancreatitis develops over many years and can gradually damage the gland. Many acute cases are mild and settle with supportive care, while chronic pancreatitis is more likely to affect digestion over time.
What causes pancreatitis most often?
Gallstones blocking the bile duct and heavy alcohol consumption are the two most common causes. In some cases the specific cause is never identified.
Would I know if I had pancreatitis?
Acute pancreatitis usually announces itself — pain in the upper abdomen that may radiate to the back, often with nausea, vomiting or fever. Chronic pancreatitis can be quieter, and is sometimes only recognised after it has led to weight loss or digestive problems.
Can an MRI diagnose pancreatitis?
MRI shows the pancreas, its ducts and the surrounding tissues in detail without using radiation. It can identify inflammation, detect gallstones, assess how much damage has occurred, and reveal complications such as fluid collections.
Is pancreatitis serious?
It can be, and sudden severe abdominal pain should always be assessed promptly. Many cases are mild, but because the condition ranges widely in severity, it is one to manage with a clinician rather than watch at home.
