[Imaging studies in the diagnosis of haemangiomas and vascular malformations].

The diagnosis of haemangiomata and cutaneous vascular malformations is based on clinical history and physical exploration. Imaging studies might be necessary to clarify and confirm the diagnosis, and in order to analyse the extent of the lesions by permitting an evaluation of their non-visible component as well as the affection of neighbouring structures. Finally, they also play an important role when it comes to planning and directing treatment, whether surgical or endovascular. The imaging techniques employed for haemangiomas and vascular malformations include: plain films ultrasound (Doppler), computerised tomography (Angio-CT), magnetic resonance (Angio-MR) and the angiographic techniques (arteriography, phlebography).
