Arthrography
Alternative names
Dynamic joint radiography. Dynamic radiography of the joints.
Definition
Arthrography consists of obtaining radiological images of the joint to be studied using an ionizing radiation emitting source (X-rays), a fluoroscopy or continuous ionizing radiation emitting source, an iodinated contrast medium, a monitor and a computer.
Unlike the simple joint radiography that uses a single ionizing radiation emitting source by means of which static radiological images of the joint studied are obtained; Arthrography also uses a fluoroscopy or continuous ionizing radiation source, which allows obtaining dynamic or moving images of the joint studied.
Preparation for the study.
Arthrography does not require prior preparation but the signing of an informed consent by the patient will be requested.
The patient must undress the anatomical area under study and remove their personal items, especially jewelry and metal objects.
You should avoid making sudden movements of the joint studied for the first 24-48 hours after the study.
What does it feel like during and after the study?
The study is painless for the patient except for the discomfort of the administration of contrast and / or local anesthetic (slight pain in the area of administration or inside the joint)
The patient may have an allergy to the local anesthetic and / or the contrast used during the study. In the case of presenting a skin rash, itching or respiratory distress during the study, it should be indicated to the radiology technician immediately.
The first hours after the study, the joint studied may present mild pain and inflammation that usually resolves in a few hours with the application of local ice and an analgesic or an anti-inflammatory by mouth.
Study risks
The arthrographic study, in general, does not imply a significant risk to health.
The embryo, fetus and children are more susceptible to radiation, so in these cases unnecessary studies should be avoided. Pregnant or suspected pregnant women (including those with an IUD) should avoid the study as much as possible and should tell the radiology technician that she is pregnant before performing it.
The patient may have an allergy to the contrast used during the study. Severe anaphylactic reaction is rare.
Skin or intra-articular inflammation / infection may occur after administration of contrast and / or local anesthetic.
Study contraindications
The patient should consult with his doctor before carrying out the study in case of:
- Pregnancy and breastfeeding.
- allergy to the contrast or local anesthetic used in the study.
- Take some kind of medication.
