Role of Multi-detector row helical CT In Diagnosis of Acquired pancreatic diseases
Raymond Adly Nazmy Farag;
Abstract
MDCT has gained a great role in clinical imaging practice in a short time. Its major advantages are fast image acquisition and improved resolution. In spite of the advent of other imaging modalities CT is still the gold standard for the evaluation of pancreatic pathology.
MDCT scanning allows quick and accurate diagnosis and staging of pancreatitis. MDCT can assess the degree of involvement and enables detection of complications including development of pseudocysts, abscess, necrosis, hemorrhage, and vascular occlusion.
Acute pancreatitis can be a mild, self-limiting disease or can be severe with significant patient morbidity and mortality. The severity of the patient’s condition is judged based on clinical, laboratory, and imaging criteria. CECT is the imaging modality of choice for evaluation of pancreatitis. It can evaluate pancreatic morphology, detect pancreatic necrosis, and depict retroperitoneal complications, and used to stage the severity of inflammation.
CT staging and CT severity index have proved to be a reliable indicator of disease severity, having shown an excellent correlation with the risk of death and the development of local and systemic complications in this population.
Mortality of acute pancreatitis is dependent on the development of potentially lethal complications that can coexist and occur at any time following an acute attack. The early detection and objective evaluation of these complications by clinical and imaging methods lead to specific treatment options in the continuous attempt to decrease mortality rates in acute pancreatitis.
Imaging plays an important role in the management of patients who have acute pancreatitis. CT and trans-abdominal ultrasound are useful to confirm the diagnosis of acute pancreatitis and to rule out other causes of acute abdomen such as gastrointestinal perforation, acute cholecystitis, acute aortic dissection, and mesenteric artery occlusion. Clinically, all these entities can mimic acute pancreatitis. In established cases of acute pancreatitis, contrast enhanced CT (CECT) is considered the criterion standard for evaluating morphologic changes of the disease, particularly in the assessment of pancreatic necrosis. CECT has become an integral part of the new classification system.
In chronic pancreatitis, contrast-enhanced multidetector CT (MDCT) is well established to assess ductal changes, calcifications, the form and shape of the pancreatic gland, and potential concomitant conditions such as pseudocysts. This also enables multiplanar, curved reconstructions for a high resolution display of the total gland and the course of the duct.
Pancreatic cancer is the 10th common malignancy and the 4th largest cancer killer in adults. Surgery offers the only chance
