A provider orders an imaging study for a patient who reports persistent chronic headaches and occasional dizziness. To obtain detailed images of the brain to rule out possible structural causes, which of the following imaging studies should the medical assistant prepare the patient for to best provide the needed information?
Magnetic Resonance Imaging (MRI) produces high-resolution images of soft tissues, making it the ideal modality for evaluating structural abnormalities in the brain that may explain chronic headaches and dizziness. A CT scan can image brain anatomy but is less sensitive to subtle soft-tissue changes and exposes the patient to ionizing radiation. Standard X-rays are primarily for bone visualization and provide almost no detail of intracranial structures. Ultrasound waves are largely blocked by the adult skull, so this modality is not suitable for routine brain imaging.
