MRI对女性盆腔胃肠道间质瘤与子宫附件肿瘤的鉴别诊断价值
Diagnostic value of MRI in differentiating gastrointestinal stromal tumors and uterine adnexal tumors in female pelvis
摘要
Abstract
Objective To explore the diagnostic value of MRI in differentiating between gastrointestinal stromal tumors and uterine adnexal tumors in female pelvis.Methods Imaging data were retrospectively collected from 42 patients admitted for pelvic mass and diagnosed with gastrointestinal mesenchymal tumor or uterine adnexal tumor by postoperative pathology in some hospital from 2016-2022,including 12 patients with gastrointestinal stromal tumor and 30 patients with uterine adnexal tumor composed of 20 ones with malignant epithelial tumors of the ovary,5 ones with ovarian sex cord-stromal tumors and 5 ones with exophytic uterine fibroids.The tumor blood vessels and normal ovarian structures were observed,and the positive rates of tumor vascular display were calculated;the location distribution of the cystic portions of gastrointestinal stromal tumors and ovarian malignant epithelial tumors was inspected;gastrointestinal stromal tumors and uterine adnexal tumors were compared in terms of conventional MRI signs including cystic or solid mass,morphology,signal characteristics and pelvic lymph nodes,and the accuracy,specificity and sensitivity of MRI for differentiating between gastrointestinal stromal tumors and uterine adnexal tumors were calculated with the postoperative pathological results as the gold standard.SPSS 26.0 software was used for statistical analysis.Results The overall display rate of tumor vascular was 80.9%,and the display rates being 75%,100%,60%and 40%for pelvic gastrointestinal stromal tumors,ovarian malignant epithelial tumors,ovarian sex cord-stromal tumors and exophytic uterine fibroids,respectively.A significant difference was found in the locations of the cystic portions between pelvic gastrointestinal stromal tumors and ovarian malignant epithelial tumors(P<0.001),while no significant differences were observed in other conventional MRI signs between the two groups(P>0.05).MRI demonstrated an overall diagnostic accuracy of 95.2%,with a sensitivity of 100%and a specificity of 83.3%.Conclusion MRI shows clearly the normal ovarian structure,ovarian vascular bundles and tumor MRI signs and has high rates for tumor vascular display,which is of great value for differentiating between gastrointestinal stromal tumors and uterine adnexal tumors in female pelvis.[Chinese Medical Equipment Journal,2025,46(9):60-64].关键词
