[Comparative study of Hexabrix and Lipiodol UF in sialography].

Many new lipid- and water-soluble contrast media can be used in sialography, the three main criteria of choice being the cost, the quality of filling, particularly of the parenchyma, and its evacuation and clinical tolerance. Duroliopaque possesses very similar physicochemical properties to those of Lipiodol UF, but a sufficiently satisfactory filling of the parenchyma is not obtained. Comparison of Lipiodol UF and Hexabrix in parotid and submaxillary contrast imaging showed good clinical tolerance for both products, but improved parenchymatous filling with Lipiodol UF. However, the more effective glandular evacuation with Hexabrix makes this the product most suitable at the present time for morphologic exploration of salivary glands.
