PURPOSEWe aimed to evaluate the benefit of adding CT texture analysis on conventional CT features ofbenign adnexal cystic lesions, especially in identifying mucinous cystadenoma.METHODSThis retrospective study included patients who underwent surgical removal of benign ovarian cysts (44 mucinous cystadenomas, 32 serous cystadenomas, 16 follicular/simple cysts and43 endometriotic cysts) at our institution between January 2015 and November 2017. TheCT images were independently reviewed by an abdominal radiologist (reviewer 1) and a resident (reviewer 2). Both reviewers recorded the conventional characteristics and performedtexture analysis. Based on reviewer 1’s results, two decision trees for differential diagnosiswere developed. Reviewer 2’s results were then applied to the decision trees. The diagnosticperformances of each reviewer with and without the decision trees were compared.RESULTSSeveral conventional features and texture analysis parameters showed significant differences between mucinous cystadenomas and other benign adnexal cysts. The first decision treeselected septum number and thickness as significant features, whereas the second decisiontree selected septum number and the mean values at spatial scaling factor (SSF) 0. Reviewer1’s performance did not change significantly with or without the use of the decision trees.Reviewer 2’s interpretations were significantly less sensitive than reviewer 1’s interpretations(p = 0.001). However, when aided by the first and second decision trees, Reviewer 2’s interpretations were significantly more sensitive than reviewer 1’s interpretations (86.4%, p < 0.001;72.7%, p = 0.001).CONCLUSIONThis study suggests the benefit of CT texture analysis on conventional images to differentiatemucinous cystadenoma from other benign adnexal cysts, particularly for less experiencedradiologists
