摘　　要：目的分析磁共振成像(MRI)评估面部填充术后填充物移位外渗的临床价值。方法选取本院58例接受过面部填充聚丙烯酰胺水凝胶(PAHG)手术病例,均在术后复查时接受MRI检查,比较T2加权成像对比频率选择饱和法(T2WI fs)、短时间反转恢复(STIR)序列、水脂分离技术(IDEAL)PAHG显示率、PAHG移位外渗检出率、主观图像质量评分、客观指标[信噪比(SNR)与对比噪声比(CNR)]。结果总共填充84处,49处出现PAHG移位外渗,STIR、IDEAL对PAHG显示率、PAHG移位外渗检出率明显高于T2WI fs(P<0.05),STIR与IDEAL对PAHG显示率、PAHG移位外渗检出率比较无显著差异(P>0.05);STIR、IDEAL图像质量评分显著高于T2WI fs(P<0.05),STIR与IDEAL比较无显著差异(P>0.05);IDEAL、STIR的SNR、CNR显著高于T2WI fs(P<0.05),且IDEAL显著高于STIR(P<0.05)。结论面部填充术后MRI检查中,与T2WI fs、STIR相比,IDEAL脂肪抑制效果较好,可以更好检出PAHG移位外渗情况。Objective To analyze the clinical value of magnetic resonance imaging(MRI)in evaluating displacement and extravasation of filler after facial filling.Methods A total of 58 patients who had undergone facial filling with polyacrylamide hydrogel(PAHG)in the hospital were selected.All of them received MRI at postoperative reexamination.The display rates of PAHG,the detection rates of PAHG displacement and extravasation,subjective image quality scores,and objective indicators[signal to noise ratio(SNR)and contrast to noise ratio(CNR)]using T2-weighted imaging with fat suppression(T2WIfs),short-tau inversion-recovery(STIR)sequence and IDEAL(Iterative Decomposition with Echo Asymmetry and Least squares estimation)fat-water imaging were compared.Results A total of 84 sites were filled,and 49 sites showed PAHG displacement and extravasation.The display rates and detection rates of PAHG displacement and extravasation using STIR and IDEAL were significantly higher than using T2WI fs(P<0.05),but there was no significant difference between STIR and IDEAL(P>0.05).Image quality scores of STIR and IDEAL were significantly higher than those of T2WI fs(P<0.05),but there was no significant difference between STIR and IDEAL(P>0.05).SNR and CNR of IDEAL and STIR were significantly higher than those of T2WI fs(P<0.05).SNR and CNR of IDEAL were significantly higher than those of STIR(P<0.05).Conclusion In MRI examination after facial filling,IDEAL has better fat suppression effect compared to T2WI fs and STIR,and can better detect PAHG displacement and extravasation.
