目标。本研究的目的是描述5例胰腺局灶性脂肪置换的典型CT和化学移位MRI表现，并评价其在胰腺局灶性脂肪置换诊断中的价值。结论：胰腺内可见局灶性低密度病变的CT表现和与化学移位相反的MRI信号强度降低有助于鉴别胰腺局灶性脂肪置换与真正的胰腺肿瘤。因此，这些影像表现避免了胰腺局灶性脂肪置换患者的侵入性诊断程序和手术。
OBJECTIVE. The purpose of this study was to describe the typical CT and chemical shift MRI findings and to evaluate their usefulness in the diagnosis of focal fatty replacement of the pancreas in five patients.CONCLUSION. The presence of a perceptible focal low-attenuation lesion in the pancreas on CT and the reduction in signal intensity of the lesion on the opposed phase of chemical shift MR images are useful for differentiating focal fatty replacement of the pancreas from true pancreatic neoplasm. Therefore, these imaging findings obviate invasive diagnostic procedures and surgery in the care of patients with focal fatty replacement of the pancreas.
