我们使用动脉自旋标记磁共振成像(ASL-MRI)评估受孕残留产物(RPOC)的血供，以阐明这种方法的临床可行性。材料和方法采用脉冲-连续ASL序列和回声平面成像(EPI)采集。连续10名RPOC患者入选。所有ASL图像均进行了目测和半定量评估，并与多普勒超声(US)和动态增强MRI(DCE-MRI)结果进行了比较。结果16次扫描中，技术成功率为93.7%(15/16)。一个失败的案例被排除在分析之外。6例患者在RPOC上显示相当高的信号，而3例患者未显示异常信号。仅多普勒超声未能发现血管增多的病例有2例，仅ASL-MRI未能发现的有3例。ASL-MRI和DCE-MRI的半定量之间存在显著的线性相关。6例ASL-MRI呈高信号的患者治疗后均行MRI随访。结论ASL-MRI对RPOC的评价在临床上是可行的，治疗后的疗效可以用来评价。然而，相对于传统成像的临床优势仍不清楚，需要评估。
ObjectivesWe evaluated the vascularity of retained products of conception (RPOC) using arterial spin-labeling magnetic resonance imaging (ASL-MRI) to clarify the clinical feasibility of this approach.Materials and methodsA pulsed-continuous ASL sequence with echo-planar imaging (EPI) acquisitions was used. Ten consecutive patients with RPOC were enrolled. All ASL images were evaluated visually and semiquantitatively and compared with the findings of Doppler ultrasound (US) and dynamic contrast-enhanced MRI (DCE-MRI).ResultsThe technical success rate was 93.7% (15/16 scans). One failed case was excluded from the analysis. Six patients showed quite high signals over RPOC, while three patients showed no abnormal signals. Doppler US alone failed to detect the hypervascular area in two cases, and ASL-MRI alone failed in three. A significant linear correlation was found between semiquantitative values of ASL-MRI and DCE-MRI. All six patients showing high signals on ASL-MRI underwent follow-up MRI after therapy. High signals in five patients decreased visually and semiquantitatively, while one patient showed signal increases.ConclusionEvaluation of RPOC using ASL-MRI was clinically feasible and response to therapy could be evaluated. However, the clinical advantages over conventional imaging remain unclear and need to be evaluated.
