The appearance of pancreatic cancer relative to normal pancreatic tissue may be hypoechoic, isoechoic or hyperechoic on transabdominal ultrasound. An ill defined hypoechoic mass is seen infiltrating into a bright pancreatic parenchyma in majority of the cases. This may be accompanied by pancreatic and biliary duct dilatation. Endoscopic Ultrasound (EUS) has a higher resolution than transabdominal ultrasound, due to the small distance between the endoscope and pancreas through the wall of the duodenum. EUS plays an important role in the preoperative staging of pancreatic cancer and also has a high efficacy in the detection of tumors smaller than 2 cm, for local T and N staging, and prediction of vascular invasion. Moreover, EUS-guided fine needle aspiration biopsy (FNA) is the best modality for obtaining a tissue diagnosis.

Transabdominal Ultrasound

Endoscopic Ultrasound (EUS)

Advantages of EUS are as follows:[4][5]

Drawbacks of EUS are as follows: [6]

  • EUS is also operator-dependent; hence its value varies with physician expertise.
