Conventional Imaging Upon presenting symptoms of abdominal pain or back pain, a common symptom of pancreatic adenocarcinoma, an abdominal x-ray or lumbar x-ray to may be performed. This exam would be performed as a preliminary image to rule out what is causing the pain; but it is not a preferred modality for diagnostic purposes. The radiographic appearance of the pancreas may show calcifications, which can be a symptom of chronic pancreatitis but not necessarily adenocarcinoma (T. Williams, personal communication, October 14, 2015).
Transabdominal Ultrasound
Initially when a patient presents with jaundice or abdominal pain, an ultrasound is frequently considered the first-line diagnostic tool. The ultrasound provides a non-ionizing imaging of the pancreas and can typically show if dilation of the pancreatic duct and/or dilation of the common bile duct is present, also known as the double duct sign (E. Lee & J. Lee, 2014). The two most common causes of a radiographic appearance of the double duct sign is carcinoma of the head of the pancreas and carcinoma of the ampulla of Vater (Goel, 2015). The ability to visualize this sign provides answers as to why the jaundice and abdominal pain is present and calls for further investigation to potentially diagnose the patient with pancreatic adenocarcinoma (E. Lee & J. Lee, 2014). US may also show a hypoechoic mass with irregular margins that can be typically appreciated as pancreatic adenocarcinoma (E. Lee & J. Lee, 2014; Pietryga &
