The ultrasound scan is a diagnostic technique which uses ultrasound (sounds which the human ear cannot hear) not radiation, so it is completely harmless. In the last 20 years there have been spectacular technical advances, obtaining a high capacity for tissue discrimination.
On the other hand it is a technique that is carried out in real time, so we can interact with the patient, asking questions, seeing the structure in movement, etc.
In general, this technique is usually associated with the study of the abdomen or pregnancy, but this is only a small part of what it is used for. It has great value in the study of the locomotor apparatus, soft tissue (breast, thyroid, testicles, etc.) and the nervous system, etc.
Using the Doppler effect which detects the movement of structures (on which are based the radar cameras on our roads) we can carry out a reliable morphological and functional study of our cardiovascular system.
Furthermore, apart from its diagnostic ability per se, it serves as a guideline for carrying out invasive diagnostic procedures (punctures and biopsies, etc.) and therapeutic procedures (infiltrations, drainages, etc.).
