Diagnostic effectiveness of infusion hepatic angiography. A comparison with the conventional technique.

The diagnostic effectiveness of infusion hepatic angiography was evaluated in 72 patients with various liver diseases, who also had conventional hepatic angiography. In a comparison of the two techniques, the infusion study was found diagnostically essential in 4 patients (6%), and afforded improved diagnosis in 52 others (72%). In 13 patients (18%), it gave equivalent information; and in 3 patients (4%), less information than the conventional technique. Infusion hepatic angiography is a useful complementary technique in anatomical liver diagnosis, especially in its ability to improve upon the diagnostic accuracy of the capillary phase of hepatic angiography.
