摘要:
目的：比较磁共振成像技术中快速平衡稳态采集（FIESTA）和单次激发快速自旋回波（SSFSE）序列在胎盘植入中的应用价值，为胎盘植入产前诊断序列选择提供参考。方法：选取佛山市第一人民医院2018年1月~2018年12月收治的35例胎盘植入作为研究对象，患者均采用FIESTA和SSFSE序列检查胎盘植入情况。比较两种序列图像质量，直接与间接征象，两种序列检查诊断价值。结果：FIESTA序列扫描对胎盘子宫轮廓和分界、图像信噪比显示情况优于SSFSE序列扫描，差异均有统计学意义（P<0.05）；FIESTA序列植入型、粘连型及穿透型等直接征象检出率高于SSFSE序列，仅植入型检出率差异具有统计学意义（P<0.05），胎盘内部存在低状信号、胎盘内部实质不匀信号、胎盘内部变粗变多血管影等间接征象检出率低于SSFSE序列，仅胎盘内部存在低状信号检出率差异具有统计学意义（P<0.05）；以手术病理检查结果作为金标准，FIESTA序列与SSFSE序列联合检出植入型、粘连型及穿透型灵敏度、特异度、准确度均高于单一序列。结论：在胎盘植入患者检查中，FIESTA序列对胎盘子宫情况显示清晰，影像质量优异，但两者在直接与间接征象检出上各有优势，两种序列联合可以有效提高胎盘植入诊断价值。
Abstract:
Abstract: Objective To compare the application value of fast imaging employing steady-state acquisition (FIESTA) and single-shot fast spin-echo (SSFSE) sequences of magnetic resonance imaging in placenta increta for providing a reference for the selection of prenatal diagnostic sequence of placenta increta. Methods Thirty-five patients with placenta increta who were admitted to the First People’s Hospital of Foshan City from January to December 2018 were selected as subjects. The patients were examined for placenta increta with FIESTA and SSFSE sequences. The image quality, direct and indirect signs and the diagnostic value were compared between two kinds of sequences. Results The contour and boundary between the placenta and the uterus as well as image signal-to-noise ratio obtained by FIESTA sequence were better than those obtained by SSFSE sequence (P<0.05). The detection rates of the direct signs of the implanted, adhesive and penetrating types by FIESTA sequence were higher than those obtained by SSFSE sequence, but only the difference in the detection rate of implanted type was statistically significant (P<0.05). However, FIESTA sequence was inferior to SSFSE sequence in the detections of indirect signs inside the placenta such as low signals, uneven signals of the parenchyma and the thickening and increased vascular shadows, but the statistical difference was only found in the detection rate of low signals inside the placenta (P<0.05). With the results of surgical pathological examination as the golden standard, the sensitivities, specificities and accuracy rates of FIESTA sequence combined with SSFSE sequence were higher than single sequence for the detection of implanted, adhesive and penetrating types of placenta increta. Conclusion The placenta and uterus in patients with placenta increta can be clearly displayed by FIESTA sequence, and the image quality is excellent. FIESTA and SSFSE sequences have their own advantages in the detection of direct and indirect signs. The combination of two sequences can effectively improve the diagnostic value for placenta increta.
