X-ray infiltration - Definition

Ask a question


Infiltration is an injection technique of different products near a nerve root or in a joint whose intended effect is the reduction of pain. They can be made using specific benchmarks when the targeted areas are superficial or injection points are easily identifiable. But in the case of deeper areas, as may be the case at the hip for example, they can be performed under radiological control: this is called ultrasound-guided or radio-controlled infiltration if the location method uses X-rays (X-rays, CT scan) or ultrasound (sonography).
