Abstract:
Objective:To explore the differential diagnostic value of abdominal diffusion-weighted imaging (DWI) combined with serum alpha fetoprotein (AFP), des-gamma-carboxyprothrombin (DCP), and the ratio of γ-glutamyl transpeptidase to alanine transaminase (GTP/ALT) in the diagnosis of benign and malignant liver tumors.Methods:Ninety liver tumor patients admitted to the Chenzhou First People′s Hospital from February 2020 to May 2022 were selected, including 48 malignant tumors and 42 benign tumors, and were divided into malignant group and benign group. The imaging findings of routine magnetic resonance imaging (MRI) and DWI examination were analyzed for two groups of patients. We compared the apparent diffusion coefficient (ADC) values, serum AFP, DCP levels, and GTP/ALT between two groups of patients. The diagnostic value of DWI, individual and combined detection of various serological indicators for malignant tumors was analyzed using receiver operating characteristic (ROC) curves.Results:There were significant differences in MRI and DWI imaging manifestations between the malignant and benign groups of patients. The ADC values and ADC index of patients in the malignant group at different b values of 50, 400, and 800 s/mm 2 were lower than those in the benign group, and the differences were statistically significant (all P<0.05). The serum AFP, DCP, and GTP/ALT of patients in the malignant group were higher than those in the benign group, and the differences were statistically significant (all P<0.05). The ROC curve analysis results showed that the sensitivity and specificity of DWI combined with serum AFP, DCP, and GTP/ALT in diagnosing liver malignant tumors were higher than those of DWI alone and each serological indicator alone. Conclusions:The combination of DWI, serum AFP, DCP, and GTP/ALT has high sensitivity and specificity in diagnosing liver malignant tumors, and has certain clinical value in distinguishing between benign and malignant liver tumors.
