 Good morning to you all. I'm Abiyo Singh Benz and I'm going to discuss the topic, the role of CT imaging, exion and coroner for diagnosis of chronic pancreatitis. That's right, introduction. Chronic pancreatitis is characterized by relentless inflammatory and fibrotic changes of the gland, eventually leading to exocline and endocrine dysfunction. It can severely impair the quality of life besides life-saving acute and long-term complications. The current incidence ranges from 4.4 to 14 per 1 lakh people with prevalence of 76.9 to 52.4 per 1 lakh people. Male predominance by a factor of 1.5 to 4.6 and a median survivor of 20 years is there. Ames to study the role of CT for diagnosis of chronic pancreatitis. Methods CT pancreas protocol, the CT pancreas protocol serves as an outline for a dedicated examination of the pancreas. It is usually conducted as a biophysic contrast study. The methods, the research study was conducted at the radio-diagnosis department of our super specialty hospital, the CT machine used in this procedure work with its 128th slide CT. CT pancreas protocol, protocol CT for solid organ involved different time phases based on IV contrasts reaching a particular structure, different processing options. Contrast related factors, negative oral contrasts, distance of stomach and the duodenum, better contrast between bowel and solid organs. IV contrasts is usually iodine based, volume and concentration is 1.5 to 1.8 meter per kilogram of 300 mg per ml. Rate is 2 to 5 ml per second. There are different phase basics are there. In non-contrast phase, it is where is the contrast seen, it is usually seen in the plane contrast or pre-contrast. Early arterial phase is usually seen in arteriogram. Then there is pancreatic, parankymen phase also known as lead arterial phase. We can see the contrast in the portal vein but it is not seen in the hepatic vein. Then there is the portal venous phase which is predominantly seen, the contrast is predominantly seen in the portal veins beginning to appear in the hepatic vein and in the IVC. Then the last is the lead phase, only fibrous structure, the liver etc. are focused. Then there is the timing of the CT pancreas protocol, the timing for acquisition. In non-contrast phase, it is usually 0 seconds. Early arterial phase, it is usually 15 seconds. Then there is pancreatic, parankymen phase also known as lead arterial phase. It is from 35 to 45 seconds. And then there is portal venous phase that is 60 to 70 seconds. In this diagram, we can see that it is the CT axial image of the pancreas. And in this image, we can see the pancreas in the midline. The pancreas, we can see there is a calcific, there is a calcific foci seen embedded in the pancreatic body region which is well visualized in this axial CT scan. And we can see in this image, we can see the pancreatic duct has been dilated mainly in the body and in the proximal tear region with the atrophic of the pancreas in mostly in its tear region. And this is the coronal image of the same patient. In this also, we can see the atrophicization of the pancreas with the calcification in the pancreatic head and the dilatation of the main pancreatic duct. Then the features of chronic pancreatitis are as follows. That is pancreatic fibrosis, fibrotic paranchymal tissue enhances on late phase, pancreatic duct dilatation with loss of tapering in the tear, irregularities of the margins of the pancreatic duct with alternating areas of stenosis and dilatation, side blood dilatation, cystic areas in pancreas, panchymal loss and atrophy, calcification and sore formation. Then there is modified Cambridge classification on CT. They are grading done here, 0 is normal, grade 1 is equivocal, grade 2 is mild, in grade 2 mild, there are the following features, 2 or more of the following, pancreatic duct dilatation 2 to 4 mm, duct irregularity, variation 1 to 2 mm, side branches of normality, 3 or more, heterogeneous paranchymal, cystic changes, 10 mm or less in size. Third is moderate pancreatitis, it is the features of mild plus MPD is dilated more than 4 mm. Then there is the last and the most severe form, the grade 4. It is moderate plus 1 on most stones, strictures, panachymal calcification of cysts more than 10 mm or there are severe duct irregularities, which we can see. Then the complications of chronic pancreatitis are as follows. Pseudosis formation, it is the most common complication. Vascular complication including cortal vein or spraining vein thrombosis without certain splenic liver infarcts. Then there are internal pancreatic pistura, obstruction of different part of GIT. In this CT axial image, we can see the pseudosis formation in the axial CT, having the pseudosis formation and also incidental finding of right hydrouretronephrosis is seen. By conclusion, diagnosis of chronic pancreatitis continues to present a clinical challenge. However, recent guidelines have brought much needed direction and clarity to this endeavor. In this review, we emphasize the role of CT in imaging chronic pancreatitis and its various complications. Overall, the CT remains the best screening tool for detection of chronic pancreatitis with diagnostic performance equal to or better than MRI. Thank you.
