[Functional vascular investigation]

Having confirmed that functional vascular investigations arouse great interest, the author has tried to sketch the profile of the "functionalist". He, like the radiologist, is a specialist who should be thoroughly acquainted with: 1. Vascular anatomy and its anomalies. 2. Electronics, so that he can recognize the limits of the apparatus he uses. 3. Circulatory physiology, so that he is able to identify the parameters being explored. 4. Above all, he must be a clinician and fully aware of the problems caused by venous and arterial pathology. These conditions fulfilled, communication between the doctor and his patient will be fruitful.
