Implication

Randomized trial assesses liver iron quantification using MRI in patients with liver iron overload, suggesting its potential as an alternative to biopsy.

Key Points

The aim is to evaluate the effectiveness of magnetic resonance imaging for diagnosing and quantifying liver iron overload.
Prospective MRI performed on 77 patients with and without liver iron overload.
Liver iron concentration determined via liver biopsy and biochemical analysis.
Signal intensity ratios and T2 relaxation times calculated using spin-echo and GRE sequences.
Liver-to-tissue signal intensity ratios correlated more strongly with liver iron concentration than T2 relaxation time.
Achieved high sensitivity (94%) and specificity (90%) with a liver-to-fat ratio threshold of 1.
Quantification of iron was accurate for concentrations between 80-300 mumol/g; above this, quantification was ineffective due to signal loss.
