The magnetic resonance imaging (MRI) features of sponges retained postsurgically in three patients are described. MRI depicted these as well-defined round masses, which were of low signal intensity on T1-weighted images and very high signal intensity on T2-weighted images. We scrutinized these masses on T2-weighted images. MRI revealed the low-signal-intensity structures to have wavy, striped, and/or spotted appearances, which raised the suspicion that they might be retained surgical sponges within mass lesions.
描述了3例患者术后留存海绵的磁共振成像（MRI）特征。MRI将这些显示为边界清晰的圆形肿块，在T1加权图像上呈低信号强度，在T2加权图像上呈非常高的信号强度。我们在T2加权图像上仔细观察了这些肿块。MRI显示低信号强度结构呈波浪状、条纹状和/或斑点状外观，这引发了怀疑，即它们可能是肿块病变内留存的手术海绵。
