Reporting 3 cases of hemangiomas of the maxillo-facial area the authors describe, proper use, of RBc scintigraphy, CT with contrast media, MR, angio-MR. Comparing these methods it will results that RBc scintigraphy is a very useful method in a screening phase providing data concerning kind of blood flow, morphology of lesions and also detecting unknown lesions by total body scanning. CT imaging with contrast media is a useful method in a presurgical phase providing the exact anatomical limits of the lesions especially when involving bone tissue. MR imaging provides precise anatomic limits specially for low flow lesions; it also provides a vascular map of the arterial afferent vessels in high flow vascular lesions, without any use of ionogenic radiations. For these reasons MR is advisable in pediatric age and allergic patients. Super-selective embolization, sclerosant therapy and surgery therapy are indicated for treatment of high flow and low flow hemangiomas.
