看到hyperdense liver density，聯想：Amiodarone toxicity, Iron deposition, Glycogen storage disease, Gold therapy(現在少), thorotrast (現在少)

  • Amiodarone therapy: 心律不整用藥，可能會有心臟病史。除hyperdense liver外，也可能伴隨有lower lung ILD, 以及focal lung infiltrates with increased attenuation.
  • Iron deposition: 可能成因有口福攝取太多，多次輸血，血液疾病（thalassemia, sideroblastic anemia）, primary hemochromatosis. 除高亮度外，可能可以發現hepatic enlargement, cirrhosis。
  • Glycogen storage disease: type I and IV有關。

***從MRI 來看

  • Primary hemochromatosis: liver, myocardium anf pancreas T2WI 比較暗，
  • Secondary hemochromatosis: liver and splen T2WI 暗
  • Glycogen storage disease: T1WI 亮

***其他注意事項：看到hyperdense liver 想到HCC and angiosarcoma 比例可能會上升，特別要注意有無tumor


Ans: amiodarone therapy
