目的 评估分析MRI增强序列对胆管细胞癌的诊断价值.方法 回顾性分析17例经病理证实的胆管细胞癌患者,均经CT增强检查和MRI T1-VIBE增强序列扫描,分析2种检查方法中的各种影像学征象,分别记录病变的位置、数目、大小、强化程度、胆管扩张程度,观察邻近动脉、门静脉受侵、门静脉内瘤栓情况,重点观察两种不同的检查方法对于病变的显示效果. 结果 MRI TlVIBE图像的肿瘤与无肿瘤肝脏组织的对比明显优于CT图像.肝内病变边界T1-VIBE增强序列更加清晰,1例病灶内可见出血,1例可见门脉左支内瘤栓;肝门部病变和肝外胆管病变VIBE增强序列显示胆管壁病变范围更加清晰;11例多发病灶者中9例VIBE序列较CT显示增多.结论 MRI TlVIBE序列能够更加清晰全面的评价胆管细胞癌的各种类型的病变,在临床诊疗过程中具有重要的诊断价值,应作为常规检查.
目的 評估分析MRI增彊序列對膽管細胞癌的診斷價值.方法 迴顧性分析17例經病理證實的膽管細胞癌患者,均經CT增彊檢查和MRI T1-VIBE增彊序列掃描,分析2種檢查方法中的各種影像學徵象,分彆記錄病變的位置、數目、大小、彊化程度、膽管擴張程度,觀察鄰近動脈、門靜脈受侵、門靜脈內瘤栓情況,重點觀察兩種不同的檢查方法對于病變的顯示效果. 結果 MRI TlVIBE圖像的腫瘤與無腫瘤肝髒組織的對比明顯優于CT圖像.肝內病變邊界T1-VIBE增彊序列更加清晰,1例病竈內可見齣血,1例可見門脈左支內瘤栓;肝門部病變和肝外膽管病變VIBE增彊序列顯示膽管壁病變範圍更加清晰;11例多髮病竈者中9例VIBE序列較CT顯示增多.結論 MRI TlVIBE序列能夠更加清晰全麵的評價膽管細胞癌的各種類型的病變,在臨床診療過程中具有重要的診斷價值,應作為常規檢查.

Objective To evaluate contrast-enhanced MRI sequence for diagnosing cholangiocarcinoma.Methods Cholangiocarcinoma was confirmed by surgery and pathology in 17 cases,all underwent preoperative CT and MRI T1-VIBE scan with contrast-enhancement sequence.We retrospectively analyzed imaging signs in two scan methods,including lesion position,number,size,enhancement degree,expansion degree of bile duct,invasion of adjacent artery and portal vein,and portal vein tumor thrombosis.The differences on detecting lesions between two methods were compared.Results The contrast to noise ratio (CNR) between tumor and liver tissue in MRI T1-VIBE images was obviously superior to that in CT images.Peripheral lesion boundary in T1-VIBE enhanced images was clearer than CT.One hemorrhage lesion was shown in T1-VIBE images,and tumor thrombosis was visible in the left branch of portal vein in 1 case.Bile duct wall lesions in T1-VIBE enhanced images was more evident than CT in hilar cholangiocarcinoma and extrahepatic cholangiocarcinoma.The VIBE enhanced images find more lesions in 9 out of 11 multiple focus cases,compared with CT images.Conclusions Contrast-enhanced MRI T1-VIBE sequence can give more comprehensive and clear evaluation on cholangiocarcinoma,and has important clinical diagnostic values.
