ObjectiveTo compare the predictive value of Balthazar computed tomography severity index (CTSI), Modified computed tomography severity index (MCTSI) and extrapancreatic inflammation on CT (EPIC) in patients diagnosed as acute pancreatitis with organ dysfunction based on the revised Atlanta classification. MethodsThe clinical data of patients diagnosed as acute pancreatitis from December 2013 to January 2014 were analyzed retrospectively. Four imaging score systems (CTSI, MCTSI, EPIC, and local complications) and two clinical score systems were assessed with ROC and AUC. Results①There were no statistical significances in the age, gender, time after onset of symptoms to CT scanning in 54 patients (P > 0.05).②CTSI, MCTSI, EPIC, and local complications were good independent predictors of organ dysfunction in the early phase (P < 0.05), while BISAP and NJSS were not (P > 0.05). ConclusionCT scoring systems can accurately evaluate organ dysfunction of acute pancreatitis in the early phase.
ObjectiveTo explore the imaging manifestations of posttransplantation lymphoproliferative disease (PTLD) for making a further understanding of this disease and its imaging diagnosis. MethodsBy the method of litera-ture review, the imaging manifestations of PTLD in the abdomen, thorax, head and neck, and central nervous system were summarized, respectively, and also the epidemiologic features, pathogenesis and pathologic classification were reviewed. ResultsPTLD is a spectrum of lymphoproliferative diseases following transplantation mainly caused by Epstein-Barr virus and immunosuppressive therapy with different pathologic types.Lesions at imaging examinations may be the first clue to diagnose, and the appearance of PTLD at imaging can vary depending on the region. ConclusionImproving the cognition of PTLD and the imaging features plays a pivotal role in identifying the presence of disease, guiding tissue sampling, and evaluating response to treatment.
