摘要:
目的 探讨磁共振动态增强（DCE-MRI）联合磁共振弥散加权成像（DWI）对肝占位性病变的诊断价值。方法 选取2022年12月-2023年12月安福县人民医院收治的61例肝占位性病变患者，其中良性病变患者48例，恶性病变患者13例，依次进行DCE-MRI与DWI检测，比较良、恶性病变患者的表观弥散系数（ADC）、速率常数（Kep）值，以手术病理结果为金标准，分析DCE-MRI、DWI及其联合检测对良、恶性肝占位性病变的诊断效能，统计其对不同肝占位性病变疾病的诊断准确性。结果 恶性肝占位性病变患者的ADC值低于良性肝占位性病变患者，Kep值高于良性肝占位性病变患者（P＜0.05）。DCE-MRI联合DWI对良、恶性肝占位性病变的诊断敏感度、特异度、准确性高于其单独检测（P＜0.05）。DCE-MRI联合DWI对不同肝占位性病变的诊断准确性均高于其单独检测（P＜0.05）。结论 DCE-MRI联合DWI在肝占位性病变检测中具有较高诊断价值。
Abstract:
Objective To explore the diagnostic value of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) combined with diffusion weighted imaging (DWI) in hepatic space-occupying lesions. Methods A total of 61 patients with hepatic space-occupying lesions admitted to Anfu County People’s Hospital from December 2022 to December 2023 were selected, including 48 patients with benign lesions and 13 patients with malignant lesions. DCE-MRI and DWI were performed in turn. The apparent diffusion coefficient (ADC) and rate constant (Kep) values of patients with benign and malignant lesions were compared. Taking the results of surgical pathology as the gold standard, the diagnostic efficacy of DCE-MRI, DWI and their combined detection on benign and malignant hepatic space-occupying lesions was analyzed, and the diagnostic accuracy of different hepatic space-occupying lesions was counted. Results The ADC value of patients with malignant hepatic space-occupying lesions was lower than that of patients with benign hepatic space-occupying lesions, and the Kep value was higher than that of patients with benign hepatic space-occupying lesions (P<0.05). The sensitivity, specificity and accuracy of DCE-MRI combined with DWI in the diagnosis of benign and malignant hepatic space-occupying lesions were higher than those of single detection (P<0.05). The diagnostic accuracy of DCE-MRI combined with DWI for different hepatic space-occupying lesions was higher than that of single detection (P<0.05). Conclusion DCE-MRI combined with DWI has high diagnostic value in the detection of hepatic space-occupying lesions.
