[Computer tomography in the detection of hemochromatosis].
Computed tomography (CT) was performed to estimate the density of the hepatic and splenic parenchyma in 18 patients with hemochromatosis. The mean CT density was 79 +/- 21 Hounsfield units compared with 61 +/- 9 (p < 0.01) in 31 controls without hepatic disease. Increased density above 79 Hounsfield units was found in eight patients out of 18 (44%). The highest density (125 Hounsfield units) was found in a patient with a serum ferritin of 6500 micrograms/l. There was an association between CT density and serum ferritin (r = 0.72, p < 0.01). The difference in density between liver and spleen gave better discrimination between patients and controls: 12 of 18 (67%) showed an increased difference in density between liver and spleen. We conclude that CT represents a non-invasive alternative to liver biopsy in cases where the latter is contraindicated. However, CT is not sensitive when serum ferritin is below 1,000 micrograms/l.
