2、~T期MRI诊断准确性分别为88.71、77.42和88.71%。直肠癌局部浸润的MRI征象与病理T分期间相关性较强(r一0.725,P<0.001)。直肠癌侵犯肠周径程度与病理T分期呈中等正相关(r一0.699,P3、ToevaluatetherelationshipbetweentheMRIsignsoflocalin—filtrationandpathologicalstagingofrectalcancer.MaterialsandMethodsSixty-twocasesofpathologicallyconfirmedrectalcancerunderwentMRscanbeforeoperation.3.0TMRsignswereanalyzedandclassified.Thenthestagingwa4、smadeaccordinglyandcomparedwithhistopath0logicalTstaging.ResultsIn62cases,theoveralldiag—nosticaccuracyofTstagingwas77.4,MRIdiagnosticaccuracyof≤T2~T4stag—ingwas88.71%,77.42and88.71,respectively.TherelationshipbetweentheMRsignsoflocalinvasionandthepathol5、ogicalTstagingwasastrongcorrelationpositive(r一0.725,P6、ftheextentofthecircumferenceinvasionsofrectalcancerareconductive收稿日期:2010-0t-28totheTstagingofrectalcancer.3.0TMR1withaphased—arraycoilisanaccurate修回日期:2010-04'09imagingtooltoevaluateTstagingofrectalcarcinoma.Thistechniqueishelpfulinplanningthesurgerypro7、grammetoensureacompleteremovalofthelateralspreadof中国医学影像学杂志2010年第18卷第5期thetumorandredUce】oca】recurrencerates.ChineseJournalofMedicalImaging2010,Vo1.18.No.5:430-434[KeyWords]rectalneoplasms;magneticresonanceimaging;neoplasmstaging直肠癌因转移和复发的危险性较大,而预后很癌患者进行8、了前瞻性的MR1分期研究,分析直肠癌差。成功的肿瘤切除主要依靠准确的肿瘤分期和适局部浸润的MRI征象与术后病理组织学肿瘤T分期合的外科技术。既往CT和直肠内超声检查(tran—的关系。srectalultrasonography,TURS)为直肠癌分期提供1材料与方法了有效的手段,但有一定的局限性。近年来,随着MRI设备和技术的改进,特别是相控阵线圈的应1.1临床资料纳入标准:术前未接受放、化疗且有用_1],其优势逐渐显现。国内采用3.OT
