CTICasesCardiac Hemochromatosis
Imaging findings
Cardiac MRI with multi-echo gradient echo sequences shows diffuse myocardial iron deposition, evidenced by rapid T2* signal drop-out and a calculated T2* value of 9.5 ms. The liver also appears jet black, indicating severe hepatic iron overload.
Key takeaways
Cardiac MRI T2* quantification is essential for diagnosing and monitoring cardiac hemochromatosis. Rapid signal drop-out and T2* values below 16 ms are indicative of significant myocardial iron deposition, with liver involvement often more severe and detectable earlier.
