“…MD-CT can determine pancreatic and extrapancreatic inflammation, but contrast enhancement must be used (27). However, enhancement material has been reported to aggravate AP, and it can also lead to worsening renal failure related to AP (28).…”

Background/Aims: The aim of this study was to measure the apparent diffusion coefficient (ADC) values detected by diffusion-weighted imaging (DWI) in acute pancreatitis and compare them with computerized tomography (CT) findings in acute pancreatitis subgrouped by the Balthazar classification. Materials and Methods: The study population included 50 patients diagnosed with clinical pancreatitis who were evaluated with both multidetector CT and magnetic resonance imaging (MRI) within 24 h of clinical presentation. We calculated pancreatic ADC values obtained from DWI (b=0 and b=1000 mm

“…Plane CT can show the changes in inflammation around the pancreas, but cannot detect necrotizing pancreatitis without the use of enhancement material [17] . However, enhancement material has been reported to aggravate acute pancreatitis [18] and it is hard to employ enhanced CT in patients with renal failure due to severe acute pancreatitis. At present, CT is the only available diagnostic imaging method of acute pancreatitis.…”

Diffusion-weighted imaging (DWI) is an established diagnostic method of acute stroke. The latest advances in magnetic resonance imaging (MRI) technology have greatly expanded the utility of DWI in the examination of various organs. Recent studies have revealed the usefulness of DWI for imaging of the liver, kidney, ovary, and breast. We report a patient with acute pancreatitis detected by DWI and discussed the efficacy of DWI in diagnosing acute pancreatitis. A 50-year old man presented with a primary complaint of abdominal pain. We performed both DWI and computed tomography (CT) for this patient. The signal intensity in a series of DWI was measured and the apparent diffusion coefficient (ADC) values were calculated to differentiate inflammation from normal tissue. Two experienced radiologists evaluated the grade of acute pancreatitis by comparing the CT findings. Initially, the pancreas and multiple ascites around the pancreas produced a bright signal and ADC values were reduced on DWI. As the inflammation decreased, the bright signal faded to an iso-signal and the ADC values returned to their normal level. There was no difference in the abilities of DWI and CT images to detect acute pancreatitis. However, our case indicates that DWI can evaluate the manifestations of acute pancreatitis using no enhancement material and has the potential to replace CT as a primary diagnostic strategy for acute pancreatitis.

“…According to the Atlanta Classification, most pancreatic abscesses arise at least 4 weeks after onset of symptoms 4 , although others diagnose 'pancreatic abscesses' after 1 50,152 , 2 153,154 or 3 86,146,147 weeks. Interestingly, when performing operative necrosectomy Adjacent to the pancreatic bed is a large collection with predominately fluid-like attenuation (white arrows).…”

Results: A total of 447 articles was assessed, including 12 guidelines and 82 reviews. Alternative definitions of predicted severity of acute pancreatitis, actual severity and organ failure were used in more than half of the studies. There was a large variation in the interpretation of the Atlanta definitions of local complications, especially relating to the content of peripancreatic collections. Conclusion:The Atlanta definitions for acute pancreatitis are often used inappropriately, and alternative definitions are frequently applied. Such lack of consensus illustrates the need for a revision of the Atlanta Classification.

Potential Harmful Effect of Iodinated Intravenous Contrast Medium on the Clinical Course of Mild Acute Pancreatitis

Abstract: Hypothesis: A worse clinical outcome might be expected in patients with acute pancreatitis (AP) who receive intravenous contrast medium for a nondynamic contrast-enhanced computed tomographic (CECT) study early during hospital admission.
