【摘要】Objective To investigate the predictive value of diffusion-weighted (DW) magnetic resonance imaging (MRI) for invasiveness of hilar cholangiocarcinoma (HC).Methods The retrospective casecontrol study was conducted.The clinicopathological data of 65 HC patients who were admitted to the Sun Yat-sen Memorial Hospital from January 2012 to November 2017 were collected.Patients received DW MRI before treatment,and 2 senior imaging doctors analyzed imaging data and measured the apparent diffusion coefficient (ADC) for the primary lesions of HC.Observation indicators:(1) MRI situations of HC;(2) relationship between ADC and clinicopathological factors;(3) receiver operator characteristic (ROC) curve analysis;(4) treatment and follow-up situations.According to patients' conditions,treatment plans were done within 2 weeks after MRI and patients underwent radical resection of HC.Follow-up using telephone interview was performed to detect tumor recurrence up to December 2017.Measurement data with normal distribution were represented as (x)±s,and comparisons between group and among group were respectively analyzed using the t test and one-way ANOVA.Spearman's rank correlation was performed to analyze the
