摘要
目的:比较磁共振肝脏容积加速采集成像(MRI-LAVA)序列与增强CT检查在肝脏结节性病变诊断中的效能。方法:选取2020年1月至2022年1月该院收治的40例肝脏结节性病变患者为研究对象,所有患者均进行MRI-LAVA序列、增强CT及病理检查。以病理检查结果作为诊断肝脏结节性病变的“金标准”,比较MRI-LAVA序列与增强CT检查在肝脏结节性病变诊断中的效能,以及对直径≤3 cm病灶的检出率。结果:病理检查结果显示,40例肝脏结节性病变患者中,恶性35例,良性5例;MRI-LAVA序列检查诊断恶性34例,良性4例;增强CT检查诊断恶性27例,良性3例;MRI-LAVA序列检查诊断肝脏结节性病变的灵敏度、准确度均高于增强CT检查,差异有统计学意义(P<0.05);病理检查结果共检出病灶60处,其中直径≤3 cm病灶38处,>3 cm病灶22处;MRI-LAVA序列检查共检出病灶54处,其中直径≤3 cm病灶34处,>3 cm病灶20处;增强CT检查共检出病灶41处,其中直径≤3 cm病灶24处,>3 cm病灶17处;MRI-LAVA序列检查对直径≤3 cm病灶的检出率高于增强CT检查,差异有统计学意义(P<0.05)。结论:MRI-LAVA序列检查在肝脏结节性病变诊断中的效能和对直径≤3 cm病灶的检出率均高于增强CT检查。
Objective:To compare efficacies of magnetic resonance liver rapid volume imaging(MRI-LAVA sequence)and enhanced CT in diagnosis of liver nodular lesion.Methods:40 patients with liver nodular lesions admitted to this hospital from January 2020 to January 2022were selected as the research objects.All patients underwent MRI-LAVA sequence,enhanced CT and pathological examination.Using the results of pathological examination as the“gold standard”,the efficacies of MRI-LAVA sequence examination and enhanced CT examination in the diagnosis of liver nodular lesions and the detection rates of the lesions with diameter≤3 cm were compared.Results:The pathological examination showed that among the 40 patients with liver nodular lesions,35 were malignant and 5 were benign.The MRI-LAVA sequence examination indicated that 34 cases were malignant and 4 cases were benign.The enhanced CT examination suggested 27 cases were malignant and 3 cases were benign.The sensitivity and the accuracy of MRI-LAVA sequence in the diagnosis of liver nodular lesions were higher than those of enhanced CT examination,and the differences were statistically significant.A total of 60 lesions were detected by pathological examination,including 38 lesions with diameter≤3 cm and 22 lesions with diameter>3 cm.54 lesions were detected by MRI-LAVA sequence,including 34 lesions with diameter≤3 cm and 20lesions with diameter>3 cm.41 lesions were detected by enhanced CT examination,including 24 lesions with diameter≤3 cm and 17 lesions with diameter>3 cm.The detection rate of MRI-LAVA sequence examination for the lesions with diameter≤3 cm was higher than that of enhanced CT examination,and the difference was statistically significant(P<0.05).Conclusions:The efficacy of MRI-LAVA sequence in the diagnosis of liver nodular lesions and the detection rate of lesions≤3 cm in diameter are higher than those of enhanced CT.
