Are the thickness and ADC values reliable to evaluate pancreas in children? A retrospective MRI study

摘要

Abstract Purpose To define the pancreatic thickness on the transverse plane and apparent diffusion coefficient (ADC) values at multiple anatomical locations in the normal pancreas of children and to evaluate inter-rater and intra-rater reliability.Methods Two reviewers measured the thickness and ADC values of the pancreas at four locations obtained from two different 1,5 Tesla MRI scanners MAGNETOM Symphony (Siemens Medical Systems, Erlangen, Germany) and Signa HDxt(GE Healthcare, Milwaukee, WI, USA). Measurements were made based on 190 retrospective MRI examinations. Patients were distributed among ten age groups for thickness measurements and three age groups for ADC measurements between 0 and 18?years.Results The thickness measurements from each segment of the pancreas were significantly correlated with patient age, height and weight (p?
