摘要
目的探讨磁共振成像(MR I)联合磁共振血管造影(MRA)和胰胆管造影(MRCP)对胰头癌诊断的价值。方法对42例胰头癌患者进行MR I、MRA和MRCP检查,并与术中探查结果及手术方式行对比分析。结果42例胰头癌患者中MRCP和MRA显示癌肿未侵犯邻近组织、血管者24例,癌肿压迫邻近门静脉、肠系膜上静脉者5例,侵犯或浸润邻近血管者10例,远处器官转移者3例。与术中探查结果相符者35例,准确率达89.7%(35/39)。行胰十二指肠切除术者28例,行内引流术者11例,3例行介入治疗,手术切除率为66.7%(28/42)。结论MRCP和MRA对胰头癌患者术前肿瘤转移和周围组织浸润,尤其是对肿瘤血管浸润可明确显示,其影像学结果对病变程度的估计及指导临床治疗决策有重要价值。
Objective To study the value of magnetic resonance imaging （MRI） combined with magnetic resonance angiography （ MRA ） and magnetic resonance cholangiopancreatography （MRCP） in the preoperative diagnosis of patients with carcinoma of head of pancreas. Methods Forty-two patients were examined by MRI, MRCP and MRA. The results were compared with the intraoperative exploration findings and operative procedures. Results The MRCP and MRA results of 42 cases demonstrated that peripancreatic tissues and blood vessels were not invaded in 24 cases, while portal vein and superior mesenteric vein were invaded by the tumor in 5 cases, and peripancreatic vessels were infiltrated in 10 eases, and 3 cases were detected with organ metastasis. Thirty-five of forty-two cases were consistent with the intraoperative exploration findings, and the accurate rate was 89.7%. Pancraticoduodenectomy was performed in 28 patients, internal drainage in 11 and interventional therapy in 3 cases. The resection rate was 66. 7%. Conclusions The results of MRCP and MRA could definitely demonstrate the preoperative organ metastasis and peripancreatic organization invasion, especially blood vessel infiltration. So the imaging results played an important role in estimating the level of the process and guiding the treatment.
