Comparison of three methods of measuring liver blood flow.

Liver blood flow was measured by dynamic 99Tcm-sulfur colloid accumulation and indocyanine green disappearance in 5 subjects, and by 99Tcm-sulfur colloid accumulation and 133Xe-wash-out in 7 subjects. Results obtained by the 99Tcm-sulfur colloid and indocyanine green methods were closely comparable, whereas the flow values estimated by the two isotope methods did not correlate well.
