Question

What factors or conditions may contraindicate the use of magnetic resonance imaging (MRI)?

a) Metallic implants, claustrophobia, pacemakers, MR-incompatible prosthetic heart valves, contrast allergy, body weight
b) Metallic implants, recent surgeries, obesity, age, respiratory conditions, history of seizures
c) Metallic implants, age, contrast allergy, body weight, history of diabetes
d) Metallic implants, pacemakers, contrast allergy, respiratory conditions, history of cancer

Answer 1

MRI scans may be contraindicated in patients with metallic implants, pacemakers, contrast allergy, respiratory conditions, and history of cancer.

Step-by-step explanation:

There are several factors or conditions that may contraindicate the use of magnetic resonance imaging (MRI). These include:

• Metallic implants: MRI scans use powerful electromagnets, which can dislodge iron-containing metallic implants.
• Pacemakers: The strong magnetic fields of an MRI can interfere with the functioning of pacemakers.
• Contrast allergy: Some patients may be allergic to the contrast dye used in MRI scans.
• Respiratory conditions: Patients with severe respiratory conditions may have difficulty lying still for the duration of the scan.
• History of cancer: Depending on the situation, MRI scans may not be recommended for patients with a history of cancer.
