[Angiodynography: initial experiences with a new sonographic method].

Abstract

Angiodynography is a further development of Duplex sonography and a new, non-invasive imaging method that places no stress on the patient and enables simultaneous sonomorphological diagnosis of the organs and soft parts as well as their blood supply. Experience to date has shown that the angiodynographic vascularisation pattern is a diagnostic criterion in the clarification of circumscribed thyroid changes. If thyroid findings appear to be unclear, e.g. in case of scintigraphic cold nodes, angiodynography can be used with success as a complementary method. It can also help to classify findings in focal lesions of the liver. Information on functional parameters are supplied for differentiating arterial and venous vascular processes. They are easier to apply, more rapid and more accurate than with Duplex sonography. A drawback is the limited depth of penetration (5 MHz transducer). Angiodynography can be appreciated quickly and easily. It appears to be not only a complement to conventional examination methods but may even replace established diagnostic methods in solving certain problems.
