摘要:
目的探讨腹部MRI动态增强扫描（DCEI）结合弥散加权成像（DWI）技术对肝脏良恶性肿瘤的鉴别诊断价值。 方法回顾性分析2019年3月~2020年3月我放射科核磁室同北京大学第一医院核磁室合作检查64例（91个病灶）肝肿瘤患者的临床资料，经手术病理证实为恶性病灶61个、良性病灶30个。患者均行MRI DCEI及DWI检查，观察肝脏病灶在上述序列上的表现特征，评估MRI DCEI联合DWI对肝脏良恶性肿瘤的鉴别诊断价值。 结果恶性病灶中DCEI表现为快进快出、DWI呈高信号者占比大于良性病灶（P < 0.05）。DCEI联合DWI诊断灵敏度、准确度高于DCEI、DWI单独诊断（P < 0.05）；特异度与DCEI诊断差异无统计学意义（P>0.05），但高于DWI（P < 0.05）。 结论良性、恶性肝肿瘤DCEI、DWI表现特征具有差异，DCEI联合DWI诊断肝肿瘤可显著提高诊断准确度和灵敏度，对肝肿瘤良恶性鉴别诊断有重要价值。 Abstract:ObjectiveTo explore the differential diagnostic value of abdominal MRI dynamic contrast-enhanced imaging (DCEI) combined with diffusion- weighted imaging (DWI) on benign and malignant liver tumors. MethodsThe clinical data of 64 patients (91 lesions) with liver tumors from March 2019 to March 2020 in our hospital were retrospectively analyzed. Sixty-one malignant lesions and 30 benign lesions were confirmed by surgical pathology. All patients were given MRI DCEI and DWI, and the features of findings of liver lesions in the above sequences were observed, and the differential diagnostic value of MRI DCEI combined with DWI on benign and malignant liver tumors was evaluated. ResultsThe proportion of patients with fast in and fast out in DCEI and high signal in DWI of malignant lesions was higher than that of benign lesions (P < 0.05). The sensitivity and accuracy of DCEI combined with DWI were higher than those of DCEI or DWI (P < 0.05). The specificity was not significantly different from that of DCEI (P>0.05), but it was higher than that of DWI (P < 0.05). ConclusionThe features of DCEI and DWI findings are significantly different in benign and malignant liver tumors. DCEI combined with DWI can significantly improve the diagnostic accuracy and sensitivity in the diagnosis of liver tumors. -
