The evaluation of enhanced CT combined with MRI of TACE surgery for primary liver cancer
增强CT和MRI在原发性肝癌TACE术后的疗效评估

摘要

目的 分析增强CT联合磁共振ADC值定量评价原发性肝癌TACE术后价值。方法 回顾性收集2020年5月-2023年5月行TACE术的40例患者资料，患者均接受增强CT联合磁共振ADC值定量评价，对比治疗效果。结果 患者术后ADC值变化、对比增强比（CER）、信号比（SIR）以及病灶直径较术前有显著变化，差异统计学意义（P﹤0.05）。而在不同b值下的ADC值比较上，术前以及术后2周、术后2月均有显著变化，差异有统计学意义（P﹤0.05）。结论 增强CT联合磁共振ADC值定量评价可了解术前术后ADC值变化，有利于区分肿瘤坏死病灶和评价治疗效果。

Abstract

Objective To analyze the quantitative evaluation of enhanced CT combined with magnetic resonance ADC values for the postoperative value of TACE in primary liver cancer.
Methods Retrospective collection of data from 40patients who underwent TACE surgery from May 2020 to May 2023. All patients underwent quantitative evaluation of enhanced CT combined with magnetic resonance ADC values, and the treatment effects were compared.
Results There were significant changes in postoperative ADC values, contrast-enhanced ratio (CER), signal-to-noise ratio (SIR), and lesion diameter compared to preoperative levels, with statistical significance (P<0.05). In terms of comparing ADC values under different b values, there were significant changes before surgery, as well as at 2 week and 2 month after surgery, and the differences were statistically significant (P<0.05).
Conclusion  s The quantitative evaluation of ADC values using enhanced CT combined with magnetic resonance imaging can understand the changes in ADC values before and after surgery, which is beneficial for distinguishing tumor necrosis lesions and evaluating treatment efficacy.
