Advanced diagnostic imaging of pancreatic cysts by multidetector computed tomography.

ABSTRACT

Nowadays, increasing use of cross sectional imaging especially multi-detector computed tomography causes greater detection of pancreatic cysts. The differentiation between pancreatic pseudocyst and cystic pancreatic neoplasm is essential in determining the proper treatment and prognosis. Typical imaging findings of benign pancreatic cystic lesion, especially in the asymptomatic patient, can be refined through imaging follow up. Fast scanning time and the thin slice of multidetector computed tomography provides a high resolution of image quality, less motion artifact and multi-planar reformation. It is a non invasive technique and entails few complications. However, in an atypical imaging pattern or if suggestive of malignant in nature, further investigation with endoscopic retrograde cholangiopancreatography (ERCP) with fine needle aspiration (FNA) for tissue diagnosis or cytology can aid in definite diagnosis.
