Computed Tomography-Guided Pancreatic Biopsy (CT-Guided Pancreatic Tissue Sampling)

Why This Test Is Done

Your doctor may recommend a CT-guided pancreatic biopsy if imaging tests (such as CT scans or MRI) show suspicious areas in your pancreas. These areas could indicate conditions like pancreatic cancer, benign tumors, or chronic pancreatitis. The biopsy helps narrow down the diagnosis by collecting tissue samples for further laboratory analysis.

How the Procedure Works

During the procedure, you’ll lie on your stomach or side while a contrast dye is injected into your bloodstream to highlight the pancreas on the CT scan. A needle guided by real-time imaging is then inserted into the pancreas to collect tissue samples. You may feel pressure or discomfort but should not feel pain during the procedure. Local anesthesia is used to numb the area.

Preparation

You’ll likely need to fast for several hours before the procedure, depending on your doctor’s instructions. Inform your doctor about any medications you’re taking, especially blood thinners, as they may need to be temporarily stopped. You may also be asked to wear a hospital gown and remove jewelry or clothing that could interfere with imaging.

What to Expect After the Procedure

After the biopsy, you’ll be monitored for a short time to ensure there are no immediate complications. You may experience mild soreness or bruising at the biopsy site, which can be managed with pain relievers. Avoid heavy lifting or strenuous activity for a few days. Follow your doctor’s instructions regarding diet, activity, and any signs of infection or bleeding.
