目的探討在3.0 T MRI中運用氫質(zhì)子波譜成像(1H-MRS)技術(shù)評估脂肪肝治療效果的可行性。方法收集臨床確診并治療的脂肪肝患者26例，分別于治療前、治療后3和6個月各行1次 1H-MRS檢查，測得 1H-MRS的水峰峰值和脂肪峰峰值、水峰峰下面積和脂肪峰峰下面積，計算肝細胞相對脂肪含量1(RLC1)及相對脂肪含量2(RLC2); 同期測量患者的甘油三酯、γ-谷氨酰轉(zhuǎn)肽酶、腹圍及體重指數(shù)，將其擬合成臨床脂肪肝指數(shù)(fatty liver index，F(xiàn)LI)。以FLI為參照標準，對不同時間點 1H-MRS所測得肝臟脂肪含量進行統(tǒng)計學(xué)分析。結(jié)果采用配伍設(shè)計的方差分析，治療前、治療后3和6個月的RLC1、RLC2值比較差異有統(tǒng)計學(xué)意義(P lt;0.05); 用SNK法做兩兩檢驗，治療前RLC1、RLC2值均分別明顯高于治療后3個月或治療后6個月的RLC1、RLC2值(P lt;0.05)。RLC1、RLC2與FLI進行秩相關(guān)性分析，均呈正相關(guān)性(r=0.476，P lt;0.001; r=0.475，P lt;0.001)?？煽啃苑治鲲@示，治療前的組內(nèi)相關(guān)系數(shù)均≥0.75，可重復(fù)性好。結(jié)論1H-MRS定量分析評估脂肪肝治療效果具有可行性，并且是一種無創(chuàng)的定量監(jiān)測方法。
