Abdominal imaging is associated with many potential uses for the different phases of contrast CT.The majority of abdominal and pelvic CT's can be performed using a single-phase, but the evaluation of some tumor types (hepatic/pancreatic/renal), the urinary collecting system, and trauma patients among others, may be best performed with multiple phases.
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. [2] 99% of the pancreas is exocrine and 1% is endocrine.
Acute exudative pancreatitis on CT scan Calcified pancreatic duct stones with some free intra-abdominal fluid. The differential diagnosis for pancreatitis includes but is not limited to cholecystitis, choledocholithiasis, perforated peptic ulcer, bowel infarction, small bowel obstruction, hepatitis, and mesenteric ischemia.

Computed tomography of the abdomen and pelvis, performed as a contrast CT, here presented in the sagittal, en:Coronal planecoronal and axial plane, with 3 mm slice thickness. It shows normal anatomy, with no injuries. The subject is a 21 year old male who had blunt trauma to the upper abdomen during motocross.
Pancreas anatomy. The Desjardins' pancreatic point or Desjardins' point is the point on the surface of the abdomen above the head of the pancreas. It is located approximately 5-7 cm off the navel on the line running from it to the right armpit. It is named after the French surgeon Abel Desjardins . [1] [2]
A minority of people with pancreatic divisum may develop episodes of abdominal pain, nausea or vomiting due to acute or chronic pancreatitis. The presence of pancreas divisum is usually identified with cross sectional diagnostic imaging, such as endoscopic retrograde cholangiopancreatography (ERCP) or magnetic resonance cholangiopancreatography ...
The pancreatic duct is generally regarded as abnormally enlarged if being over 3 mm in the head and 2 mm in the body or tail on CT scan. [9] Pancreatic duct or parts of pancreatic duct can be demonstrated on ultrasound in 75 to 85% of people. [10] Pancreatic ductal carcinoma is a common form of pancreatic cancer.
A pancreatic pseudocyst is a circumscribed collection of fluid rich in pancreatic enzymes, blood, and non-necrotic tissue, typically located in the lesser sac of the abdomen. Pancreatic pseudocysts are usually complications of pancreatitis , [ 5 ] although in children they frequently occur following abdominal trauma .
