Role of ultrasound guidance in the diagnostic and interventional procedures of pancreatic lesions

Dr. Sanjay Jha, Dr. Rakesh Mehra

Abstract :

Ultrasound (US) is an important diagnostic tool for the evaluation of the pancreas. It is also a fundamental imaging technique to guide percutaneous interventions for several pancreatic diseases like fluid aspiration and drainage, invasive diagnosis by means fine–needle aspiration and core–needle biopsy, tumour ablation by radiofrequency, microwaves, irreversible electroporation, cryoablation, and high–intensity focused US. Technical improvements, such as contrast media and fusion imaging, have recently increased precision and safety and reduced procedure–related complications. New techniques for the ablation of pancreatic tumours, such as contrast–enhanced US and multimodality fusion imaging, have been recently developed and have elicited a growing interest worldwide. The purpose of this article is to review the most up–to–date role of US in percutaneous procedures for pancreatic diseases, also focusing on new techniques and applications.
