Abstract

This study evaluated whether temporal changes from the dynamic late phase to the hepatobiliary phase using gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid supported liver tumor classification. A total of 147 patients with 165 lesions (hepatocellular carcinoma [HCC], metastases, and hemangiomas) underwent 3.0 T MRI. Quantitative liver lesion contrast (Q-LLC) and its rate of change (%) at 3, 10, and 15 min postcontrast were analyzed. Tumors were stratified according to albumin-bilirubin (ALBI) grade. For ALBI grade 1, the Q-LLC significantly differed at 3 min and 10 min (P < 0.05). Q-LLC increased over time, and the rate of change was the lowest in HCC, followed by metastases, and was the highest in hemangiomas. Significant differences in the rate of change were observed among tumor types for ALBI grade 1 (P < 0.01). These findings suggest that the Q-LLC rate of change may aid in liver tumor classification, particularly in patients with preserved liver function.

基于磁共振成像肝胆相衬时间变化的肝脏病变分类：初步研究。

本研究使用钆-乙氧基苄基-二乙烯三胺五乙酸评估从动态晚期到肝胆期的时间变化是否支持肝肿瘤分类。共147例165个病变（肝细胞癌、转移瘤和血管瘤）接受3.0 T MRI检查。分析定量肝病变对比（Q-LLC）及其在对比后3、10、15 min的变化率（%）。根据白蛋白-胆红素（ALBI）分级对肿瘤进行分层。对于1级ALBI， Q-LLC在3分钟和10分钟时差异显著(P
