A patient arrives for an imaging appointment and reports having had a hip replacement surgery with metal implants. Which imaging modality should be avoided to prevent potential complications?
Computed Tomography (CT) scan
X-rays
Ultrasound
Magnetic Resonance Imaging
Magnetic Resonance Imaging (MRI) uses powerful magnetic fields and radio waves to create detailed images of the body. Patients with certain metal implants cannot have an MRI because the strong magnetic field can potentially cause the metal implants to move or heat up, posing a risk to the patient. This is why an MRI should be avoided in patients with metal implants unless specifically confirmed to be MRI-safe by the manufacturer. Conversely, other imaging modalities, such as a CT scan, X-ray, or ultrasound, do not use magnetic fields and are generally safe for patients with metal implants.
