[Differential diagnosis of angiodysplasias using angiography and CT with special reference to the MR tomographic aspects].
The basic prerequisite for a rational therapy of angiodysplasia is differentiated diagnostics, especially the differentiation between arteriovenous malformations, haemangiomas, and venous malformations. Angiography reveals the arterialisation, arteriovenous fistulas, CT infiltrations of bone and soft-tissue. MRT demonstrates completely the extent of haemangiomas because of its bright signal intensity in the T2-weighted images. Hence, differentiation of malignant vessel tumours and malformations with rapid blood flow is possible, because the signal intensity is much lower in MRT. The three supplementary methods allow a correct diagnosis of angiodysplasia.
