Magnetic resonance imaging (MRI)
Description
- Magnetic resonance imaging is a noninvasive procedure that identifies tissues, tumors, and vascular abnormalities.
- It is similar to CT scanning but provides more detailed pictures.
Preprocedure interventions
- Remove all metal objects from the client.
- Determine whether the client has a pacemaker, implanted defibrillator, or other metal implants such as a hip prosthesis or vascular clips because these clients cannot have this test performed.
- Remove intravenous fluid pumps during the test.
- Provide precautions for the client who is attached to a pulse oximeter because it can cause a burn during testing if coiled around the body or a body part.
- Provide an assessment of the client with claustrophobia.
- Administer medication as prescribed for the client with claustrophobia.
- Determine whether a contrast agent is to be used and follow the prescription related to the administration of food, fluids, and medications.
- Instruct the client that he or she will need to remain still during the procedure.
