Contrast agents in medical imaging are advanced tools used in computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound. These agents allow doctors to detect abnormalities inside the body and diagnose various conditions. So, do contrast agents in medical imaging cause side effects?

Facial nerve palsy, also known as peripheral seventh cranial nerve palsy, is a condition in which a patient partially or completely loses movement in the muscles on one side of the face. The condition occurs when the facial nerve (cranial nerve VII) is damaged. To detect and diagnose facial nerve damage, doctors may order MRI (Magnetic Resonance Imaging) or CT (Computed Tomography) scans.
