OBJECTIVE
The aim of this study was to demonstrate the MR characteristics of secondary hemochromatosis (transfusional versus erythropoietic).
MATERIALS AND METHODS
Magnetic resonance images of five patients with transfusional (n = 3) or erythropoietic (n = 2) hemochromatosis were reviewed.
RESULTS
The liver of all patients had low signal intensity in all pulse sequences. The spleen had low signal intensity in all patients with transfusional iron overload, but normal signal intensity in erythropoietic hemochromatosis, which had similar MR findings to idiopathic hemochromatosis. However, the pancreas had variable signal intensity.
CONCLUSION
On MRI the signal intensity of the spleen may allow distinction between transfusional and erythropoietic hemochromatosis.
目的
本研究的目的是展示继发性血色素沉着症（输血性与促红细胞生成性）的磁共振成像（MR）特征。
材料与方法
回顾了5例输血性（n = 3）或促红细胞生成性（n = 2）血色素沉着症患者的磁共振图像。
结果
所有患者的肝脏在所有脉冲序列中均呈低信号强度。脾脏在所有输血性铁过载患者中呈低信号强度，但在促红细胞生成性血色素沉着症中信号强度正常，其MR表现与特发性血色素沉着症相似。然而，胰腺的信号强度有所不同。
结论
在磁共振成像上，脾脏的信号强度可用于区分输血性和促红细胞生成性血色素沉着症。
